Driving on Snow or Ice
Most of the time, those places where the tires meet the
road probably have good traction.
However, if there is snow or ice between the tires and
the road, you can have a very slippery situation. You will
have a lot less traction, or grip, and will need to be
very careful.
What is the worst time for this? Wet ice. Very cold snow
or ice can be slick and hard to drive on. But wet ice can
be even more trouble because it may offer the least
traction of all. You can get wet ice when it is about
freezing, 32°F (0°C), and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition — smooth ice, packed, blowing,
or loose snow — drive with caution.
If you have the Traction Control System (TCS), it will
improve your ability to accelerate when driving on
a slippery road. Even if your vehicle has TCS you will
want to slow down and adjust your driving to the
road conditions. Under certain conditions, you may
want to turn the TCS off, such as when driving through
deep snow and loose gravel, to help maintain vehicle
motion at lower speeds. See
(TCS) on page 4-9
.
If you do not have TCS, accelerate gently. Try not to
break the fragile traction. If you accelerate too fast, the
drive wheels will spin and polish the surface under
the tires even more.
