Introduction
Mechanical defects related mainly to brakes, tires, wheels, and coupling devices are a determining factor in more than 10% of heavy vehicle accidents. They also cause a significant loss of
productivity in the transportation of goods and passengers industry. Yet, most of those defects
could be detected during a proper inspection of the vehicle before it is used.
Either the driver or a person designated by the operator must perform the vehicle inspection in
order to ensure that it complies with the standards in effect. The Highway Safety Code specifies
that all heavy vehicles must have been checked within the previous 24 hours, otherwise a new
“circle check” must be carried out.
The purpose of the circle check is to ensure that:
• the principle components of the vehicle are in good condition;
• the vehicle’s owner and operator are informed of the repairs to be made;
• no vehicles with major defects are operated on our roads.
The ultimate objective is to improve safety for all road users.

What is the circle check?
•
The circle check is a sight and sound inspection of
the accessible components of a vehicle that makes
it possible to:
• detect defects as early as possible;
• quickly notify the owner and operator of any
defects detected;
• prevent the vehicle from being operated when
its condition poses a risk of an accident or a
breakdown.
•
Important! Drivers must carry out these
inspections safely.
Vehicles subject to a circle check
Road vehicles with a gross vehicle
weight rating (GVWR)1 of 4,500 kg
or more
For example:
• Ambulances;
•
•
•
•
•
•
•
•
•
•
Cement mixers;
Tank trucks
Fire trucks;
Straight-body trucks;
Snow removal trucks;
Vans;
Pickup trucks;
Trailers;
Semi-trailers;
Road tractors;
Emergency response vehicles;
Equipment transport vehicles (compressors, well
drills, concrete pumps, cranes mounted on a truck
chassis).
Combinations of road vehicles
that include at least one vehicle
with a GVWR or 4,500 kg or more
For example:
• A pickup truck with a GVWR of less than 4,500 kg
to which is hitched a trailer or semi-trailer with
a GVWR of 4,500 kg or more;
1. GVWR (or gross vehicle weight rating) = net weight + maximum load capacity.
A pickup truck with a GVWR of 4,500 kg or
more to which is hitched a trailer or semi-trailer
with a GVWR of less than 4,500 kg;
• A pickup truck with a GVWR of 4,500 kg or
more to which is hitched a trailer or semi-trailer
with a GVWR of 4,500 kg or more (each
vehicle in the combination has a GVWR of
4,500 kg or more).
•
Since the entire vehicle combination is
subject to the circle check, both vehicles
must be inspected – not only the vehicle
with a GVWR of 4,500 kg or more.
Buses, minibuses and tow trucks
(regardless of GVWR)
For example:
•
Motor coaches;
•
Minibuses;
School buses;
Paratransit minibuses;
• City buses;
• Tow trucks (all types).
•
Heavy vehicles required by an emergency service
or in the event of a disaster;
•
Farm tractors;
•
Farm machinery (e.g. combine-harvesters);
Road vehicles with a GVWR
of less than 4,500 kg transporting
dangerous substances and
requiring the display of safety marks
•
Farm trailers (e.g. a hay trailer owned by a farmer
and used for farming purposes);
•
Heavy vehicles used by a natural person for
personal ends, i.e. other than for commercial
or professional purposes (e.g. a truck used to
move household belongings, a motor home, etc.);
•
Straight-body trucks with two or three axles
used to:
•
•
Vehicles or combinations of vehicles (automobiles,
pickup trucks, etc.) requiring the display of safety
marks, for example:
–– transport unprocessed farm, forest or fishery
products, provided the driver is also the
producer, or
Vehicles exempt from
a circle check
•

Tool vehicles
–– Graders,
–– Loaders,
–– Back hoes,
–– make the return trip, provided the truck is
either empty or used to transport products
mainly used in the operation of a farm,
forest or fishery.
vehicle be driven if the circle check has not been
carried out within the regulatory time frame.
Who is required to perform the
circle check?
The driver must perform the circle check of the
vehicle he or she is driving.
The circle check can also be performed by a person
designated by the operator. In that case, the
operator becomes accountable for the circle check
and the driver may accept or refuse the report.
• If the driver accepts the report
He or she makes sure that the circle check is
valid (carried out within the previous 24 hours)
and co-signs the report to acknowledge it.
Accepting the report does not render the driver
accountable for the circle check, but the driver
must keep the report up to date and record
any defects observed during the trip.
•
If the driver refuses the report
The driver must perform a new circle check and
fill out a new report.
Is the circle check mandatory?
The circle check is mandatory for all vehicles
subject to this inspection. Therefore, a driver cannot
drive a vehicle and an operator cannot let a

•
The person designated by the operator can
be a driver. In that case, it is important that
the circle check report indicate that this
driver performed the circle check as the
person designated by the operator.
Particularities for buses,
minibuses, tow trucks
and emergency vehicles
In the case of a bus, a minibus, a tow truck or
an emergency vehicle, the driver can accept and
co-sign the circle check report completed by the
previous driver, even if the latter person is not a
person designated by the operator to carry out the
circle check.
•
If the driver accepts the report
He or she makes sure that the circle check is
valid (carried out within the previous 24 hours)
and co-signs the report to acknowledge it.
Accepting the report then renders the
driver accountable for the circle check
carried out by the previous driver, as it was
not carried out by a person designated by the
operator. The driver must also keep the report
up to date and record any defects observed
during the trip.
If the driver refuses the report
The driver must perform a new circle check and
fill out a new report.
When must the circle check be
performed?
Before getting behind the wheel, drivers must
make sure that a circle check of their vehicle
was completed within the previous 24 hours.
If this is not the case, a new circle check must
be performed.2
However, if the circle check was not performed by
a person designated by the operator, the driver
must perform a new circle check, even if one was
completed within the previous 24 hours, as the
driver cannot co-sign the circle check report.
Note that this rule does not apply to buses, minibuses, tow trucks and emergency vehicles, as the
driver can co-sign the circle check report completed
by the previous driver, even if that driver is not a
person designated by the operator to perform the
circle check.
2. In the case of buses, minibuses and emergency vehicles, Saturdays, Sundays and statutory holidays are not taken into account in the 24-hour period following the last circle check, on the condition that
the vehicle remains parked on those days.
a new circle check and thus assume responsibility
for it.
When they are at the wheel, drivers must
organize their activities so as to be able
to perform a new circle check before
the prescribed 24-hour period expires. For
example, for a circle check completed at
7:00 a.m. on June 12, the driver must
perform a new circle check before 7:00 a.m.
on June 13 otherwise he or she will be
prohibited from driving the vehicle.
Vehicles used by
more than one driver
Buses, minibuses, tow trucks
and emergency vehicles
As indicated in the section entitled “Who is
required to perform the circle check?”, if the circle
check was performed by a person designated by
the operator, each driver must read the report,
make sure the circle check was performed within
the previous 24 hours, co-sign the report if he
or she accepts it and be sure to keep it updated.
If a driver refuses the circle check performed
by the designated person, he or she must perform
11
If the circle check was performed by a driver who
is not a person designated by the operator,
successive drivers can accept the circle check
report and co-sign it or perform a new circle
check. If the driver co-signs the report, the driver
at the wheel of the vehicle is accountable for
the circle check performed by the previous driver.
The driver must also keep the report up to date
and report any defects observed during the trip.
Other vehicles subject
to the circle check
When a vehicle is used by more than one driver,
each driver must perform a circle check before
getting behind the wheel. However, if the circle
check was performed by a person designated by
the operator, the other drivers can simply co-sign
the report if they accept it.
In the event that a driver refuses a circle check
report completed by a person designated by the
operator, he or she must perform a new circle
check and complete a new report. All subsequent
drivers will also have to do so because the most
recent circle check was not performed by a person
designated by the operator.
If the circle check is not performed by a person
designated by the operator, a driver who once
again uses a vehicle for which he or she has
performed a circle check within the previous
24 hours is not required to complete a new circle
check report. However, the driver must make sure
that the report he or she has completed is on
board the vehicle and that it still accurately
reflects the vehicle’s condition. Therefore, when
another driver has used the vehicle in the meantime, it is recommended that the driver perform a
new circle check or read the other driver’s circle
check report in order to update his or her report if
any defects have been detected since he or she
completed the report.

Vehicles used by team drivers
When the vehicle is used as a team, the following
method is recommended if the operator has not
designated one of the drivers to perform the circle
check: the first driver performs the circle check
and fills out the circle check report; the relief
driver performs a new circle check and fills out a
new report before getting behind the wheel. Both
reports remain valid for a period of 24 hours.
If the operator has designated one of the drivers
to perform the circle check, the other driver can
read the report before getting behind the wheel
and either:
•
co-sign the report if he or she accepts it; or
•
perform a new circle check and fill out a new
report if he or she refuses it.
Motor coaches used
by team drivers
When preparing to take the wheel, the relief
driver can co-sign the first driver’s circle check
report if he or she accepts it, even if the preceding
driver was not designated by the operator to
perform the circle check. In such a case, the driver
behind the wheel is accountable for the circle
check performed by the preceding driver. The driver
must also keep the report up to date and record
any defects observed during the trip.
If the driver is unable to determine whether
a problem is actually a defect, he or she
should nevertheless report the problem
to the operator, who will then make the
necessary verifications.
Who is responsible for reporting
defects detected during the
trip?
Drivers are responsible for reporting defects
detected during the trip, even if the circle check
was performed by a person designated by the
operator.
Special considerations
Drivers:
•
the road test is carried out within a 15-kilometre
radius from the location where the vehicle is
being repaired;
•
the vehicle is not carrying any goods, except
the equipment with which it is permanently
fitted;
•
the vehicle is not carrying any passengers,
other than those involved in the road test;
•
the most recent circle check report or job card
is on board the vehicle.
•
are in the best position to detect symptoms
of unusual behaviour in their vehicle;
•
must always be able to carry out an inspection
of their vehicle and recognize the defects
normally detected during a circle check.
Road tests
For a road test, the circle check is not required if
all of the following conditions are met:
Fire department vehicles
The circle check for a fire department vehicle must
have been performed within 24 hours of the
vehicle leaving or returning to the fire station.
When the vehicle stays in the fire station, the
circle check must be performed at least once
every 7 days.
Buses or minibuses used
for urban transit and operated
by a public transit authority
This particularity only applies when the following
conditions are met:
•
the circle check is performed by a person
designated by the operator;
•
the vehicle is a bus or minibus used for urban
transit and operated by a public transit authority.
Lists of defects
What is a list of defects?
•
48 hours, if the vehicle remains parked indoors
for this entire period;3
The list of defects is a checklist that enumerates
the components to inspect and the defects that
can be detected on a vehicle. It is used to
determine whether defects noted during a circle
check are minor or major.
•
24 hours from the time the vehicle is called into
service.
There are three lists of defects that must be used
during the circle check.
The circle check remains valid for either of the
following periods, whichever comes first:
List 1
Heavy vehicles, other than
those covered by lists 2 and 3
List 2
Buses (other than motor
coaches), minibuses and trailers hauled by a bus, minibus
or motor coach
List 3
Motor coaches exclusively4
Must the list of defects always
be on board the vehicle?
Operators are required to:
The list of defects is mandatory and must always
be on board the vehicle.
•
place the applicable list of defects on board
every heavy vehicle under their responsibility;
•
make sure the driver keeps the list on board the
vehicle.
3. Saturdays, Sundays and statutory holidays are taken into account in the 48-hour period from the time the circle check was performed if the vehicle remains parked indoors on those days. This rule only
applies to circle checks performed by a person designated by the operator for that purpose for buses and minibuses operated by a public transit authority and used for urban transit.
4. If a motor coach is not subject to a preventative maintenance program (PMP) recognized by the Société de l’assurance automobile du Québec, the driver must make sure to have on board the report of
the inspection specific to motor coaches and List 3. The owner must complete this report every 12,000 km or every 30 days, whichever comes first, and place the report on board every motor coach under
his or her responsibility.

Drivers are required to:
•
•
make sure the list of defects that applies to the
heavy vehicle under their responsibility is and
remains on board the vehicle;
surrender the list to any peace officer who asks
for it.
Is the format for the list of
defects regulated?
The operator must provide a list of defects in the
format prescribed by the Regulation respecting
safety standards for road vehicles. They cannot
change the texts, the order in which the defects
are presented or the numbering. They can,
however, add elements in the section entitled
“Specific inspections required by the operator”.
Sample compliant lists are appended to this guide.
Mechanical component

designate performs the circle check;
Categories of defects
Minor Defects
A minor defect does not pose an immediate
threat to the safety of the driver or other
road users, but can deteriorate quickly
in certain cases. A vehicle with a minor
defect is prohibited from being operated if
repairs are not performed within 48 hours.
–– ensuring all mandatory components are
inspected.

Drivers:
–– performing the circle check, unless they accept
the circle check and co-sign the report;
>> from the person designated by the
operator,
>> from the preceding driver (buses, minibuses, tow trucks and emergency vehicles);
–– reporting any defects noted during the trip.
Major Defects
A major defect poses an immediate threat to
the safety of the driver and other road users.
A vehicle with a major defect is prohibited
from being operated.
Principal components to inspect
during a circle check
The circle check covers the various components of
a vehicle, namely:
1. Coupling devices
2. Frame and cargo body
3. Heater/defroster
4. Driver controls
5. Steering
6. Windshield wiper/washer
7. Emergency material
8. Headlights and lights
9. Tires
10. Doors and other openings
11. Glass and mirrors
12. Wheels, hubs and fasteners
13. Seat
14. Suspension
15. Fuel system
16. Exhaust system
17. Electric brake system
18. Hydraulic brake system
19. Pneumatic brake system
20. Passenger transport
15
Vehicles are not necessarily equipped
with all the components referred to in
the list of defects (e.g. hydraulic brakes).
In such cases, the components do not have
to be inspected. However, when certain
components with which a vehicle must be
equipped are missing, their absence constitutes a defect that must be reported.
If the driver detects a defect that does not
appear on the list, or if the driver is informed
of such a defect, it is recommended that
the driver enter the defect in the circle
check report and report it to the operator,
who can have the repairs made and
prevent the situation from deteriorating.
When and how should a defect
be reported?
Presence of defects
What to do if a defect
is detected?
Minor defects
Owners must maintain their heavy vehicles in
good mechanical condition. They must therefore
be informed of any defect so that it can be corrected
and maintain the right to operate the vehicle.
A minor defect must be entered in the circle
check report and reported to the operator
before the next circle check or within 24 hours,
whichever comes first.
What defects must be reported?
It is recommended that a minor defect be
reported as soon as possible.
• The sooner the operator is informed, the more
quickly the repairs can be made. In some cases,
the defect can even be repaired before the
vehicle is taken back out on the road.
Drivers must report any defect that appears in the
list of defects that applies to the vehicle they are
driving, regardless of whether the defects are
minor or major.

•
Drivers must comply with the notification time
frame requirements if another driver then gets
behind the wheel of the vehicle. The first driver
must have reported the minor defect before
the next circle check.
Owners’ responsibilities when a
defect is detected
Owners must correct any defect of which they
have been informed.
•
A major defect must be entered in the circle
check report and immediately reported to
the operator. A vehicle with a major defect is
prohibited from being driven or operated.
Operators’ responsibilities when
a defect is reported
When operators receive a copy of a circle check
report that includes a defect, they are required to:
•
The circle check report must be filled out during
every circle check, even if no defects are detected.
Minor defect
Owners have 48 hours to have the necessary
repairs made in order to maintain the right to
operate the vehicle.
Major defects
When must it be filled out?
Major defect
The vehicle is prohibited from being operated
as long as the necessary repairs have not been
made.
Circle check report
•
sign the copy of the circle check report;
What is a circle check report?
•
immediately inform the owner of the defect;
•
send the owner a copy of the circle check report.
A circle check report is a document that allows the
driver or the person designated by the operator to
inform the operator of the results of the inspection
and, if applicable, the defects detected. The report
also attests to the validity of the circle check.
I drive within a 160-km radius. Do I have
to fill out a circle check report? Yes, it is
mandatory under all circumstances.
Who fills out the
circle check report?
The person who performs the circle check must
fill out the circle check report and enter his or
her observations.
Where must it be kept?
Keeping the completed and valid circle check
report on board the vehicle is mandatory; the
vehicle cannot be put into operation if this report
is not on board the vehicle.
What are the operators’
obligations?
•
the vehicle’s licence plate number or the unit
number found on the registration certificate;
Operators must make sure that the person who
performs the circle check enters all the
required information in the report.
• They must make sure that the driver keeps
the circle check report on board the vehicle.
• They must not allow the vehicle to be
operated if the circle check report is not on
board the vehicle.
•
the operator’s name;
•
the date and time at which the circle check was
performed;
•
the municipality or location on the road where
the circle check was performed;
•
any defects noted during the trip;
•
any defects noted during the circle check.
If no defect was noted, this must be indicated
as well;
•
the name of the person who performed the
circle check (printed legibly);
When must the report be sent to
the operator?
•
a declaration, signed by the driver or the
person who performed the circle check,
attesting that the vehicle was inspected in
accordance with applicable requirements;
Drivers must send the original copy of the circle
check report to the operator no later than 20 days
after it is completed.
•
if the driver did not personally perform the
circle check, his or her signature to attest that
he or she read the report and accepted it;
•
What are the owners’
obligations?
When a vehicle is used by an operator who is not
the owner of the vehicle, the owner must obtain a
copy of the circle check report.
What information must the
circle check report contain?
The circle check report can be presented in various
forms (a sample model is appended to this guide),
but must contain the following information:
•
17
the odometer reading.
You should use the licence plate number if
you are travelling outside Québec, as some
jurisdictions do not accept the unit number.

Québec carriers operating on the territories of other
Canadian jurisdictions benefit from reciprocity as
regards the circle check. Regulations in effect in
Québec on this subject comply with National
Safety Code (NSC) Standard 13 prescribed by
the Canadian Council of Motor Transport
Administrators.
There may, however, be some differences
concerning minor and major defects, and it is
the operator’s responsibility to be aware of
those differences.

Inspection Methods
What method should be used
to perform the circle check?
The methods presented in this guide allow you to
perform a circle check quickly, effectively and
safely. However, there is no mandatory method.
What is important is to:
19
•
choose a safe place on flat terrain;
•
remain vigilant to avoid falls and injuries;
•
adopt a position that provides you with a good
view of the accessible components provided for
in the circle check;
•
remain attentive throughout the circle check to
clues that may indicate a defect (e.g. traces of
fluid on the ground, audible air leaks).
Using the same inspection routine may help
you save time and make sure you don’t forget
anything.
What material should
be used to perform
the circle check?
Moreover, since the applicable list of defects must
be kept on board the vehicle, drivers can use it as
a checklist as they perform the circle check. Thus,
the numbers that appear in parentheses in each
of the following methods refer to the lists of defects and enable drivers to identify minor or major
defects.
•
A flashlight;
•
A clean rag;
•
A hammer.

BRAKE.
the low pressure warning devices (19.1,
19.2, 19.A)
If the low pressure warning devices are not
already in operation, pump the brake pedal a
few times to lower the air pressure in order to
determine, using the pressure gauge, the air
pressure at which the warning devices (buzzer,
light, visual) are activated. They must activate
before the air pressure in the system drops to
less than 380 kPa (55 psi).
If the low pressure warning devices are in
operation when the vehicle is started, this
check can be carried out without further lowering
the pressure. You must make sure that the air
pressure is equal to or above 380 kPa (55 psi)
when the warning devices switch off.

19.B)
While the engine is idling and the air compressor
is operating, fully depress the brake pedal and
keep it fully depressed. Watch the pressure
gauge and make sure the compressor can
reach and maintain air pressure of at least
620 kPa (90 psi).
• the pressure regulator (stopping the compressor) (19.3)
While the air compressor is still in operation, let
the engine run and make sure the compressor
switches off when the air pressure is between
805 kPa (117 psi) and 945 kPa (137 psi).
•
During this step, the engine can be run at a
slightly higher RPM (approximately 1,000 RPM)
in order to increase the air pressure a little
more quickly.
STOP THE ENGINE and check:
• for leaks and the pressure in the brake
system (19.4, 19.C)
Press on the brake pedal and keep it depressed
while checking for air leaks (visible on the pressure gauge or audible).
RESTART THE ENGINE and check:
•
the pressure regulator (starting the compressor) (19.3)
While watching the pressure gauge, slowly
lower the air pressure until the compressor
switches back on. Make sure it switches on
before the air pressure reaches 550 kPa (80 psi).
–– Try to delicately move the vehicle forward by
shifting the transmission into a forward gear
(or the highest gear that lets you move the

If your vehicle is equipped with drum
brakes with self-adjusting brake levers,
a simple procedure allows you to make
sure that the play compensation or the
space between the brake linings and
the drum is optimal. To follow this
procedure, when the brakes are cold,
you must:
1.Release the parking brakes.
2.Bring the system up to maximum air
pressure (120 psi).
3.Fully depress the brake pedal for
five seconds and then release it
completely.
4.Carry out this procedure four or five
times in a row to ensure the play
compensation is complete.

Inspections related to the pneumatic brake system
are identified in blue in the text below.
START THE ENGINE and RELEASE THE PARKING
BRAKE.
Check:
• the low pressure warning devices (19.1,
19.2, 19.A)
If the low pressure warning devices are not
already in operation, pump the brake pedal a
few times to lower the air pressure in order to
determine, using the pressure gauge, the air
pressure at which the warning devices (buzzer,
light, visual) are activated. They must activate
before the air pressure in the system drops to
less than 380 kPa (55 psi).
If the low pressure warning devices are in
operation when the vehicle is started, this
check can be carried out without further lowering the pressure. You must make sure that the
air pressure is equal to or above 380 kPa (55 psi)
when the warning devices switch off.
• the performance of the compressor (14.B,
19.B)
While the engine is idling and the air compressor
is operating, fully depress the brake pedal and
keep it fully depressed. Watch the pressure gauge
and make sure the compressor can reach and
maintain air pressure of at least 620 kPa (90 psi).
10. The vehicle must be equipped with at least three lamps, three reflectors or three flares, failure of which constitutes an offence.

•
the pressure regulator (stopping the compressor) (19.3)
While the air compressor is still in operation, let
the engine run and make sure the compressor
switches off when the air pressure is between
805 kPa (117 psi) and 945 kPa (137 psi).
During this step, the engine can be run at a
slightly higher RPM (approximately 1,000 RPM)
in order to increase the air pressure a little
more quickly.
STOP THE ENGINE and check:
•
for leaks and the pressure in the brake
system (19.4, 19.C)
Press on the brake pedal and keep it depressed
while checking for air leaks (visible on the
pressure gauge or audible).
RESTART THE ENGINE and check:
•
the pressure regulator (starting the compressor) (19.3)
While watching the pressure gauge, slowly
lower the air pressure until the compressor
switches back on. Make sure it switches on
before the air pressure reaches 550 kPa (80 psi).
Continue with the following inspections:
•
the accelerator (4.1, 4.A);
•
the parking brake (engaging and releasing)
(19.5);
•
the clutch control mechanism (if the vehicle is
equipped with a manual transmission) (4.1);
•
the power steering (5.B);
•
the service brake (19.D):
–– Drive forward slowly (by delicately and completely releasing the clutch pedal in the case
of a manual transmission) and check to make
sure the wheels are turning freely.
–– Turn the steering wheel to one side then the
other to make the wheels move to make sure
that the power steering is operating
properly.
–– Press on the clutch pedal (if applicable) and
the brake pedal to stop the vehicle. This will
allow you to make sure the service brake is
working properly, as well as the clutch in the
case of a manual transmission.
–– apply the parking brake.
–– With the transmission in neutral, press on
the accelerator without reaching the maximum RPM, and release the accelerator to
make sure the engine returns to idle.
–– Try to delicately move the vehicle forward by
shifting the transmission into a forward gear
(or the highest gear that lets you move the
vehicle forward in the case of a manual
transmission, e.g. by shifting into third gear).
Make sure the parking brake maintains the
vehicle stationary.
–– Release the parking brake.
Shift the transmission back into neutral, apply
the parking brake and check:
•
the engine’s exhaust system (exhaust gases
infiltrating the cab if there are holes in the
floorboard) (16.A);
•
the brake lights when safe installations allow
you to do so or with the assistance of a second
person (8.1, 8.B).
Fill out the circle check report.
If your vehicle is equipped with drum
brakes with self-adjusting brake levers,
a simple procedure allows you to make
sure that the play compensation or the
space between the brake linings and
the drum is optimal. To follow this
procedure, when the brakes are cold,
you must:
1.Release the parking brakes.
2.Bring the system up to maximum air
pressure (120 psi).
3.Fully depress the brake pedal for
five seconds and then release it
completely.
4.Carry out this procedure four or five
times in a row to ensure the play
compensation is complete.

Circle Check
(Mechanical Component)
38
Introduction
During the circle check, you must carry out a
sight and sound inspection of the accessible
components identified in the list of defects
that applies to the vehicle you are using.
These lists, which include all of the systems
and mechanical parts to inspect, are appended
to this document.
Systems
Each system (coupling, steering, etc.) is designated by a colour and a number. This number
corresponds to the one that appears in the list
of defects. Thus, system “1. Coupling Devices”
of the mechanical component corresponds to
the first system that appears on each of the
three lists; system “2. Frame and Cargo Body”
corresponds to the second system, etc.
Summary tables
The presentation of each system begins with
a table that summarizes the following points:
Parts covered
Parts covered by the circle check.
Defects
The minor and major defects that may affect
the parts covered. A number code (e.g. 1.1)
corresponds to a minor defect, whereas an
alphanumeric code (e.g. 1.A) corresponds to a
major defect. Areas shaded in grey means
that there are no defects affecting the part
covered by the inspection.
Vehicles subject to a circle check
If an “X” appears in a column, this part must
be inspected for the vehicle to which the list
applies. If the space is shaded in grey, there
are no parts to inspect.
Photos and illustrations
Photos and illustrations have been added
as examples to make everything easier to
understand.
Circle check report
Lastly, a sample circle check report is
appended to this guide. This document
attests to the validity of the circle check
and is used to inform the operator of the
results of the inspection and, if applicable,
any defects that have been detected.

Occupational Injury Prevention
This section presents the risks of occupational injuries to which individuals who carry out the circle
check are exposed and the various ways in which
they can be prevented.
In more than 80% of cases, occupational injuries to
heavy vehicle drivers occur while they are away
from the wheel of their vehicle. These accidents
occur when drivers climb down from the cab or as
they carry out various duties such as handling or
transferring cargo, performing a circle check, tarping
or securing the load.
It should be noted that drivers who have good
reasons to believe their vehicle has defects that
are likely to jeopardize their health and safety
can refuse to drive the vehicle, even if they are
pressured into doing so.
139
Refusing to perform work
Businesses under provincial
jurisdiction
Under section 12 of the Act respecting occupational
health and safety, a driver employed by a business
under provincial jurisdiction may refuse to drive a
vehicle he or she considers hazardous to his or her
health or safety:
“A worker has a right to refuse to perform particular work if he has reasonable grounds to believe
that the performance of that work would expose
him to danger to his health, safety or physical wellbeing, or would expose another person to a similar
danger.”
Businesses under federal jurisdiction
Under section 128 of the Canadian Labour Code,
Part II, a driver employed by a business under federal
jurisdiction can refuse to drive a vehicle he or she
considers hazardous to his or her health or safety:
“Subject to this section, an employee may refuse to
use or operate a machine or thing, to work in a
place or to perform an activity, if the employee
while at work has reasonable cause to believe that
a.the use or operation of the machine or thing
constitutes a danger to the employee or to another employee;
b.a condition exists in the place that constitutes a
danger to the employee;
c.the performance of the activity constitutes a
danger to the employee or to another employee.

Risks and how to prevent them
Inspections under the hood
Risks
•
Slipping caused by mud or ice in the bumper
footholds;
•
Falling while raising the hood;
•
Sustaining a back injury (while handling the hood,
slipping or falling);
•
Sustaining an injury from a dropping hood
or cab;
•
Sustaining burns while touching a hot component
in the engine compartment;
•
Sustaining a musculoskeletal injury as a result
of overexertion while raising the hood.
Engine compartment under the hood
• Before opening the hood, make sure the footholds (openings in the bumpers in most cases)
are free of any material that could cause your
foot to slip.
•
Before opening the hood, test its resistance
to opening as it could stick as a result of ice
or heat.
Prevention
When you unlatch the hood, lift each corner to
make sure it is not stuck. This will spare you the
excessive effort required to open a stuck hood.
14. Tilt the cab only if the inspection cannot be carried out using the panels provided for that purpose.
Once the hood is open, make sure it will stay in
that position.
• If possible, avoid climbing onto the tire to carry
out the inspection. Instead, find support on a
flat surface.
• While the engine is running, only carry out a
visual inspection. Never place your hand
between engine components to avoid sustaining
burns from a hot component or getting your
hand stuck in a belt.
•
Engine compartment under a tilt cab14
• Stay far enough back that you will not be hit by
the cab when tilting it open or shut.
• Block the cab if there is no safety mechanism to
prevent it from falling as a result of a pressure
burst.
Engine compartment with doors
•
Make sure the engine compartment doors are
completely open and locked in place.
Getting in and out of the vehicle
Risks
•
Falling and slipping that could cause back injuries,
sprains or contusions while climbing in or out of
the cab.
Prevention
•
As a point of support, choose a fixed object,
such as the grab handles, and avoid using the
steering wheel.
•
Make sure the running boards are free of any
slippery material (mud, ice, etc.).
•
Install non-skid running boards that are wide
enough to provide adequate foot support
(wider than 18 cm).
•
Apply the three-point support principle when
getting in or out of the cab.
•
Step down from the cab backward rather than
jumping out.
•
Avoid placing obstacles in the footrests (e.g. a
shoe brush).

142
Inspecting the vehicle’s exterior
•
Wear appropriate shoes or boots.
Prevention
Risks
•
If possible, wear reflective clothing when you
stop your vehicle on the side of the road.
•
•
Use a flashlight as needed to increase visibility
in the dark.
•
•
Being struck by a moving vehicle;
Falling while walking on a slippery or uneven
surface.
Prevention
•
•
Choose a location that is:
–– level and free of snow or ice;
–– well lit in order to see any uneven areas in
the ground;
–– sheltered from wind and traffic.
Apply the parking brake.
Hitching and unhitching
the semi-trailer
Risks
Sliding, falling or striking a fixed object while
unlocking the fifth wheel;
• Sliding and falling while;
–– climbing onto or down from platform providing access to the coupling device,
–– plugging in the lighting cable and the
connection lines;
• Sustaining an injury from overexertion while
turning the crank to raise the landing gear.
•
Use a hook that is long and curved enough to
avoid having to stretch or lose your balance
while unlocking the fifth wheel.
•
143
Install metal grating that extends to the base
of the fifth wheel when the lines cannot be
connected from the ground. This will provide
you with a flat, non-skid surface to stand on.
•
Consider installing handrails or handles that
will make it easier to use the “three-point
support” technique.
•
Position yourself parallel to the semi-trailer,
extending the leg closest to the trailer slightly
behind you for better support. Place the crank in
a position that will require the least amount of
effort to operate.
