SECTION 9 NEUTRALISATION OF RACES – SAFETY CAR
A compulsory riders briefing on these Regulations must be conducted by the Clerk of the Course
or his Deputy prior to any race in which the use of Safety Cars is intended. The Safety Cars if they
are to go on the track must be equipped with Yellow Flashing lights. The words “Safety Car” should
be clearly indicated on the back and the sides of the car. The Driver of the Safety Car should be the
holder of an ACU or FIM Clerk of the Course or Competition Licence for Road Racing, a MSA
Competition Licence or an ARDS Licence. All “Safety Car” drivers must be assisted in the car by a
Race Official who is in constant contact with the Clerk of the Course.
If during a race of 20 miles or more an incident other than rain puts at risk the safety of the
competitors and renders impossible the normal progress of the competition the Clerk of the Course
(Grade National A or above or of Grade National B with the prior individual approval of the Road
Race Committee) may decide to neutralize the race.
The following procedure will be adopted:
1.
A Red Flag with a White Diagonal Cross must be displayed at the selected Marshals Posts
during the whole of the neutralisation period.
2.
A White Board showing the words “Safety Car” will be displayed at the Start Line during the
whole of the neutralisation period.
3.
Riders must immediately slow down. Overtaking is forbidden. The Track Marshals will record
all infringements and report them to the Clerk of the Course.
4.
The pit lane exit will be closed to competitors.
5.
When the leading competitor approaches the start line at the end of the lap that the
neutralisation was decided a “Safety Car” equipped with two flashing Yellow Lights on the roof
will enter the track with two flashing lights switched on.
6.
The competitors will end up in single file behind the “Safety Car” without overtaking it.
7.
Competitors may now enter the pits but all other rules must be complied with.
8.
After stopping at the pits competitors must line up at the pit lane exit and must only rejoin
the circuit when instructed to do so by the official with a Green Flag or when the Green
Light at that location is switched on. These instructions will be given 10 seconds after the last
competitor in line behind the “Safety Car” has passed that point. Competitors must join the
back of the line and MUST NOT overtake. The pit lane exit will then be closed and competitors
must wait for the next lap.
292
ROAD RACING
AUTO CYCLE UNION HANDBOOK 2015
9.
During the last lap of the neutralisation period the “Safety Car” will switch off the Lights on the
roof to indicate to the competitors that the “Safety Car” will enter the pit lane at the end of that
lap and the race will resume.
10. When the “Safety Car” has left the track overtaking is forbidden up until the start line, where
a Green Flag will be waved and the Red Flag with the White Diagonal Cross immediately
withdrawn.
11. The pit lane exit will then be permanently re-opened.
12. The race will continue normally.
13. Unless otherwise decided by the Clerk of the Course, each lap completed by the “Safety Car”
will be counted as a race lap. A Board displaying the new actual number of laps remaining will
be displayed on the start line when the green flag is waved. If the race is eventually stopped
under SR 10.1 whilst the “Safety Car” is deployed the result will be according to the position at
the last completed lap before the “Safety Car” was introduced.
14. No Protest may be lodged against the decision of the Clerk of the Course regarding the number
of laps remaining in order to complete the race.
15. All other rules of the race must be observed.
16. Exceptions – Clubman Endurance races only
1. In Clubman Endurance races, the Clerk of the Course is authorised to deploy the Safety Car
at the earliest convenient moment irrespective of the position of each rider in the race.
2. A Fast Intervention Vehicle may be despatched immediately ahead of the Safety Car
3. No Protest may be lodged against the effect of any laps lost or gained in respect of Articles
16.1 and 16.2 mentioned above
SECTION 10 INTERRUPTION OF A RACE
10.1IF THE CLERK OF THE COURSE DECIDES TO INTERRUPT A RACE DUE TO CLIMATIC
CONDITIONS OR SOME OTHER REASON, THEN RED FLAGS WILL BE DISPLAYED AT
THE FINISH LINE AND AT ALL FLAG MARSHALS’ POSTS.
1.
Riders must immediately slow down and return to the pit lane, or as directed by the marshals
upon instructions from the Clerk of the Course.
2.
Only riders still racing when the red flag is displayed will be counted as finishers.
3.
The results will be the results taken at the last point where the leader had completed a full
lap without the red flag being displayed calculated as in the principle set out in the following
example:
Example of a race consisting of 30 laps:
If a Red Flag is shown when the leader is on his 10th lap after completing his 9th lap and all
other riders have not completed the 9th lap, then the race result will be 9 laps completed, and
the second part will consist of 21 laps.
Exception: if the race is interrupted after the chequered flag, the following procedure will apply:
4.
For all the riders to whom the chequered flag was shown before the interruption, a partial
classification will be established at the end of the last lap of the race.
5.
For all the riders to whom the chequered flag was not shown before the interruption, a partial
classification will be established at the end of the penultimate lap of the race.
6.
The complete classification will be established by combining both partial classifications as per
the lap/time procedure.
7.
If the results calculated show that less than three laps have been completed by the leader of the
race and by all other riders on the same lap as the leader, then the race will be null and void and
a completely new race will be run. If it is found impossible to re-start the race, then it will be
declared cancelled and the race will not count for any Championship.
8.
If three laps or more have been completed by the leader of the race, and all other riders on the
same lap as the leader, but less than two-thirds of the original race distance, rounded down to
AUTO CYCLE UNION HANDBOOK 2015

ROAD RACING
293
the nearest whole number of laps, then the race will be restarted. If it is found impossible to
restart the race, then the results will count and half points will be awarded in any Championship.
If the results calculated show that two-thirds of the original race distance rounded down to the
nearest whole number of laps have been completed by the leader of the race, then the race will
be deemed to have been completed and full Championship points will be awarded.
Exception: Where a race is interrupted at a meeting of below National Status the Clerk of the
Course is permitted to decide that the race has been completed or to run a new race over a
distance appropriate to the prevailing conditions.
SECTION 11 RE-STARTING A RACE THAT HAS BEEN INTERRUPTED
11.1IF A RACE HAS TO BE RE-STARTED, THEN IT WILL BE DONE AS QUICKLY AS POSSIBLE,
CONSISTENT WITH TRACK CONDITIONS ALLOWING. AS SOON AS THE RIDERS HAVE

laps of each rider at the time he crossed the finish line at the end of the last part of the race.
5.
Exception: Provisions of Article 10.10 may apply according to the status of the meeting. (The
discretion of the Clerk of the Course to decide at meetings of lower than National status).
SECTION 12 FINISH OF A RACE AND RACE RESULTS
12.1 FINISH OF A RACE

When the leading rider has completed the designated number of laps (or the designated time in
the case of Endurance) for the race, a Chequered Flag will be displayed at the finishing line.
12.2THE CHEQUERED FLAG
1.
After the Chequered Flag is displayed to the leading Rider no other Rider is permitted to enter
the track from the Pit Lane.
2.
If a Rider closely precedes the leader during the final lap before the finish line the Official
will show to the Riders and to the Leaders simultaneously the Chequered Flag and the Blue
Flag. This will indicate to the Leader that he has completed the race and to the Rider closely

294
4.
5.
ROAD RACING
AUTO CYCLE UNION HANDBOOK 2015
of the Rider whose Front Wheel leading edge crossed the finish line first. In the case of Ties, the
Riders concerned will be ranked according to the best lap times they achieved in the race.
Should the end of the race signal inadvertently or otherwise be displayed before the leading
rider completes the scheduled number of laps, or before the scheduled race time has been
completed, the race will be deemed to have finished.
If the chequered flag is given to the leader then a result will be drawn accordingly, but if the
chequered flag is given to a competitor other than a leader then the result will be taken when
the leader last crossed the start/finish line.
Should the end of the race signal be advertently delayed, the race will nevertheless be deemed to
finish at the correct moment and competitors be classified accordingly.
The Clerk of the Course may require machines to be presented for post Practice or Race
verification. Where this is required the Riders must be informed prior to the start of the
Practice or Race that they must attend the “Parc Ferme”.
12.3 RACE RESULTS
1.
When the Race has been completed as described above the Results will be based on the order in
which the Riders crossed the finish line and the number of laps that they have completed.
2.
When the Race has been declared completed by the Clerk of the Course following an
Interruption under Article 10.3, the result will be established according to the procedure
described in Articles 10.4–10.6 for a race interrupted after the Chequered Flag.
3.
In either of the cases described in 1) and 2) above. To be counted as a Finisher and be included
in the results a Rider must have completed 75% of the actual race distance. He must also have
crossed the finish line on the track and not in the Pit Lane within two minutes after the winner
and be in contact with his machine.
4.
A new Lap record can only be established during a race.
5.
Both for the Practice and for the Race, the lap time is the subtraction of the time between two
consecutive crossings of the finish line.

minimum First Aid Personnel).
An ambulance may act as a Medical Centre BUT if so it must be a vehicle in addition to the
minimum ambulance requirement.
4.
First Aid Personnel A person holding a current certificate of First Aid competency. (Where
an event is open to the public event organisers should ensure that all First Aid personnel are
insured against malpractice for the event concerned).
5.
Fast Intervention Vehicle (FIV)
1. A Fast Intervention Vehicle is a compulsory requirement at all Road Race events.
2. Such a vehicle requires a driver, a Doctor, and appropriate medical equipment. If the driver
is not a First Aid Person, then such a Person must be present in the vehicle. This vehicle must
be immediately available to proceed to an incident, if called to do so, upon instructions from
the Clerk of the Course.
3. A FIV must not be used in place of an ambulance.
4. A Fast Intervention Vehicle must be equipped with visible signals (flashing lights).
5.
At a meeting of below National status no ambulance or Fast Intervention Vehicle is allowed to
be moved onto the course or its immediate verges whilst racing or practice is in progress on any
part of the circuit. This means that in the circumstances of an Ambulance or Fast Intervention
Vehicle being required on the circuit, the Red Flags must first be displayed and the race or
practice brought to an actual and effective halt before the vehicle is deployed.
Note: This restriction is not applicable where the Clerk of the Course has decided to neutralise
the race by use of the Safety Car in accordance with the provisions of Chapter 9 of the Road
Race Regulations.
6.
During Sighting Lap: Stationary or moving Ambulances, Fast Intervention Vehicles, and
the like, may be encountered anywhere on the circuit when riders are dispatched from the
Assembly Area on their “sighting lap” to the start line prior to the start of a race. This “sighting
lap” is not considered to be either Practice or Racing and riders must always be prepared to
encounter such vehicles. When such a vehicle or vehicles are on the track the Yellow Flags will
be displayed in the appropriate section of the course.
Special Notes
2 MOs must be present at the start of every meeting and be present for the duration of the meeting
unless accompanying a patient to hospital. If vehicles or First Aid personnel leave the circuit to
convey a patient to hospital then the minimum requirements for the event to continue are 1 MO, 1
FIV, 2 Ambulances and 4 First Aid personnel.
6.
Medical Examination
At any time during a meeting the Clerk of the Course may require a competitor to undergo a
medical examination to determine his fitness to participate. The decision of the Medical Officer
is a matter of fact without right of protest.
13.2 TRACK SAFETY PRECAUTIONS
1.
The safety precautions of circuits will be as laid down for each Permanent Course Licence or
Temporary Course Certificate following an inspection of the course.
2.
It should be generally realised that the organisers of speed events have a legal responsibility to
the general public and therefore it is the duty of these organisers to ensure that all reasonable
precautions are taken to protect the public.
3.
Whilst organising Clubs are insured under the Promoters Third Party Policy in respect of their
legal liability, it is a condition of the policy that the promoters of an event must comply strictly
with the National Sporting Code and any additional requirements as may be specified by the
Permanent Course Licence or Temporary Course Certificate.
296
ROAD RACING
Clubs failing to do so stand in grave danger of any claims being repudiated to the Club by the
insurers under the terms of the policy covering legal liability.
The safety precautions to be adopted are provided with the Permanent Course Licence or
Temporary Course Certificate for the particular course but the following general requirements
must be observed.
The attention of organisers is drawn to the provision of the NSC which stipulates that no
alteration of the requirements contained in the Permanent Course Licence or Temporary
Course Certificate shall be made without the prior approval, in writing, of the ACU.
It is recognised that circumstances may arise in which it is necessary to make certain alterations
to the course on the day of the meeting but any such alterations must be approved by the
Stewards of the Meeting and details given in their report to the permit issuing authority.

14.8 CONTROL OF EXHAUST SOUND LEVEL
1.
The Clerk of the Course will disqualify any machine which exceeds the maximum permitted
sound level, or which in his opinion is deemed to be excessively noisy. An official sound level
test results form will be completed at each meeting and will be submitted by the Clerk of the
Course to the Stewards of the meeting.
2.
Noise limit in force for all machines is a maximum of 105dB/A. For testing the fixed RPM
specified in 6 below will be used.
3.
The noise test will be conducted with the microphone placed at 50 cm from the exhaust pipe
at an angle of 45° measured from the centre-line of the exhaust end and at the height of the
exhaust pipe, but at least 20 cm above the ground. If this is not possible, the measurement can
be taken at 45° upwards.
4.
During a noise test, machines not equipped with a gear box neutral must be placed on a stand.
5.
The driver shall keep his engine running out of gear and shall increase the engine speed until it
reaches the specified Revolutions Per Minute (RPM). Measurements must be taken when the
specified RPM is reached.
6.
Due to the similarity of the piston stroke in different engine configurations within the capacity
classes, the noise test will be conducted at a fixed RPM. For reference only, the mean piston
speed at which the noise test is conducted, is calculated at 13 m/sec (2-stroke engines) and
11 m/sec (4-stroke engines).

For Supermono class, Vintage and Classic prior to 1973, the test RPM will continue to depend
upon the mean piston speed corresponding to the stroke of the engine, according to the table
produced in the ACU Sound Control Regulations.
The noise level for engines with more than one cylinder will be measured on each exhaust end.
A machine which does not comply with the noise limits may be presented several times at prerace control.
For Supermono class only, when presented for examination, the correct stroke must be
stamped in a clearly visible position on the crankcase.
For Wankel machines, the noise level will be measured at 6000 RPM.
The surrounding noise should not exceed 90 dB/A within a 5 metres radius from the power
source during tests.
Apparatus for noise control must be to international standard IEC 651, Type 1 or Type 2. The
sound level meter must be equipped with a calibrator for control and adjustment of the meter
during periods of use.
The “slow response” setting must always be used.
Due to the influence of temperature on noise tests, all figures are correct at 20°C. For tests taken
at temperatures below 10°C there will be a + 1 dB/A tolerance and for tests below 0°C, a + 2
dB/A tolerance.
Noise control after the competition. In a competition which requires a final examination of
machines before the results are announced, this examination must include a noise control
measurement of at least the first three machines listed in the final classification. At this final
test, there will be a 3 dB/A post race tolerance.
Guidelines for the use of Sound Level Meters
1. The Sound Inspector must arrive in sufficient time for discussions with the Clerk of the
Course and other Chief Technical Officials in order that a suitable test site and testing policy
can be agreed.
2. Sound level measuring equipment must include a compatible calibrator, which must be used
immediately before testing begins and always just prior to a re-test if a disciplinary sanction
may be imposed. Two sets of equipment must be available in case of failure of tachometer,
sound level meter or calibrator during technical control.
3. Before testing, the Sound Inspector should if possible liase with another official who has
noise test equipment including calibrators, in order to agree the accuracy of the official sound
level meter.
4. In other than moderate wind, machines should face forward in the wind direction.
(Mechanical noise will blow forward, away from microphone).
5. ‘Slow’ meter response must be used.
6. ‘A’ weighted setting on sound level meter.
7. Always round down meter reading, that is: 103.9 dB/A = 103 dB/A.
8. T
ype 1 meter: deduct 1 dB/A
Type 2 meter: deduct 2 dB/A
9. Below 10° Celsius: deduct 1 dB/A
Below 0° Celsius: deduct 2dB/A
All tolerances are accumulative. Action taken will depend on the sporting discipline concerned,
and decisions taken during prior discussions with the Clerk of the Course.
14.9 EXHAUST PIPES
1.
The end of the exhaust pipe or pipes must not project beyond any part of the vehicle or its
bodywork. Exhaust gases must not be discharged so as to raise dust or foul the tyres or brakes,
or inconvenience a following rider. The end of the exhaust pipe for a minimum distance of
30mm must be horizontal and parallel (within a + or −10 degree tolerance) to the fore and aft
302
ROAD RACING
2.
centre line of the machine. It must not extend beyond a line drawn at a vertical tangent to the
rear edge of the motorcycle rear tyre.
For sidecars the exhaust pipes must not extend beyond the limits of the sidecar on the sidecar
side and must not extend more than 330mm from the centre of the machine on the opposite
side unless contained within the streamlining.
AUTO CYCLE UNION HANDBOOK 2015
14.10 SUPERCHARGERS/TURBOCHARGERS
1.
The use of superchargers/turbochargers is prohibited unless specifically allowed in the
regulations for a specific class. An engine, whether two stroke or four stroke, coming within
any one of the recognised classes, as determined by the capacity of the working cylinder shall
not be considered as supercharged/turbocharged, when in respect of one engine cycle, the total
capacity, measured geometrically, of the fuel charging device or devices, including the capacity
of the engine working cylinder, if used for inspiriting the fuel, does not exceed the maximum
capacity of the class in question. The intracylinder injection of fuel shall not be considered as
supercharging/turbocharging.
14.11 HANDLEBARS
1.
The width of handlebars for motorcycles up to 80cc is not less than 400mm. For all other
machines (including sidecars) not less than 450mm. Grips must be attached in such a way that
at least the minimum width is reached when measured between the outside ends of the grips.
Exposed handlebars must be plugged with a solid material or rubber covered.
2.
The minimum angle of rotation of the handlebar on each side of the centre line or mid-position
must be 15 degrees for solo motorcycles and sidecars. Whatever the position of the handlebars
the front wheel must never touch the streamlining, if any. Stops must be fitted to ensure a
minimum clearance of 30mm between handlebar with levers and the tank when on full lock to
prevent trapping the rider’s fingers (see diagram 3, at the end of Road Race Section).
3.
Handlebar clamps must be carefully radiused and engineered so as to avoid fracture points in
the bar.
14.12 CLUTCH AND BRAKE LEVERS
1.
All handlebar levers (clutch, brake, etc.) must be, in principle, ball ended or be rounded
(minimum thickness of this flattened part 14mm). These ends must be permanently fixed and
form an integral part of the lever.
2.
The maximum length of control levers measured from the pivot-point to the extremity of
the ball must not exceed 200mm. Each control lever (hand and footlevers) must be mounted
on an independent pivot. The brake lever if pivoted on the footrest axis must work under all
circumstances, such as the footrest being bent or deformed.
3.
For all types of motorcycles, throttle controls must be self-closing when not held by the hand.
14.13 MUDGUARDS
Mudguards are not compulsory. If fitted, the following rules will apply:
1.
They must project laterally beyond the tyre on each side. The rear mudguard must cover at least
120 degrees of the circumference of the rear wheel, and the angle contained by a line drawn
from the rear end of the rear mudguard to the centre of the rear road wheel and a line drawn
horizontally through the centre of the road wheel must not exceed 20 degrees.
2.
The front mudguard must cover not less than 100 degrees of the circumference of the front
road wheel. The angle contained by a line drawn from the rear end of the front mudguard to
the centre of the front road wheel and a line drawn horizontally through the centre of that road
wheel must not exceed 20 degrees.
3.
Similarly, the angle contained by a line drawn from the front end of the front mudguard to the
AUTO CYCLE UNION HANDBOOK 2015
ROAD RACING
303
centre of the front road wheel and a line drawn horizontally through the centre of that road
wheel must not be less than 45 degrees nor more than 60 degrees.
14.14 OPEN TRANSMISSION GUARDS
1.
For all motorcycles, if the primary transmission is exposed, it must be fitted with a guard as a
safety measure. The guard must be conceived in such a manner that under no circumstances
can a rider or the passenger come into accidental contact with the transmission parts. It must
be designed to protect the rider from injuring his fingers.
2.
For Sidecars, a guard is required if secondary transmission is not shielded by the bodywork.
3.
A (chain) guard must be fitted in such a way as to prevent trapping between the lower chain
run and the final driven sprocket to rear wheel.
14.15 FOOTRESTS
1.
The footrests for the rider must be placed not higher than 100mm above a line passing through
the centre of the wheels with a machine loaded and in front of a vertical line passing through
the centre of the rear wheel.
2.
They must be positioned to give easy access to any control pedals.
3.
The ends of the footrests must be rounded with a solid spherical radius of not less than
8mm. Footrests may be of a folding type but in this case must be fitted with a device which
automatically allows them to return to the normal position, the integral protection is to be
provided at the end of the footrest which must have at least 8mm solid spherical radius.
14.16 OIL SUPPLY PIPES
Oil lines containing positive pressure must, if replaced, be of steel re-inforced construction with
swaged or threaded connectors. All drain plugs must be tight and drilled and wired into position. All
oil filters must be securely fastened.
14.17 OIL CATCH TANKS & BREATHER SYSTEMS
Where an oil breather pipe is fitted the outlet must discharge into a catch tank located in an easily
accessible position and which must be emptied before the start of the race. The minimum size of a
catch tank shall be 250cc for gearbox breather pipes and 500cc for engine breather pipes.
14.18 PETROL AND OIL FILLER CAPS
Petrol and oil filler caps when closed must be leak proof. They must be securely locked to prevent
accidental opening.
14.19 PETROL TANK BREATHERS
Where petrol tank breather pipes are fitted, non-return valves must be fitted to those pipes.
