OPERATING THE SPREADER
DRIVING AND SPREADING ON SNOW
AND ICE
Here are some tips for driving in these conditions:
• Drive defensively.
CAUTION
• Do not drink, then drive or spread ice control
materials.
Drinking and then driving or spreading is
very dangerous. Your reflex, perceptions,
attentiveness and judgement can be affected
by even a small amount of alcohol. You can
have a serious or even fatal collision if you
drive after drinking. Please do not drink then
drive or spread ice control materials.
• Spread or drive only when you have good visibility
for operating a vehicle.
• If you cannot see well due to snow or icy
conditions, you will need to slow down and keep
more space between you and other vehicles.
• Slow down, especially on higher speed roads.
Your headlamps can light up only so much road
ahead.
Follow your vehicle owner's manual instructions for
driving in snow and ice conditions. Remember when
you drive on snow or ice, your wheels will not get good
traction. You cannot accelerate as quickly, turning
is more difficult and you will need longer braking
distance. Wet and hard packed snow or ice offers the
worst tire traction. It is very easy to lose control. You
will have difficulty accelerating. If you do get moving,
you may have poor steering and difficult braking which
can cause you to slide out of control.
Lit. No. 95362/95363, Rev. 05
• If you are tired, pull off in a safe place and rest.
• Spreader size reduces driver visibility to the rear
of the vehicle due to spreader size and location.
We recommend OSHA compliant backup alarm
for all governed employers.
• Keep your windshield and all glass on your vehicle
clean to see around you.
• Dress properly for the weather. Wear layers of
clothing, as you get warm you can take off layers.
