Hydroplaning does not happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing
on the road. If you can see reflections from trees,
telephone poles, or other vehicles, and raindrops dimple
the water's surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just is not a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
Notice: If you drive too quickly through deep
puddles or standing water, water can come in
through your engine's air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle.
If you cannot avoid deep puddles or standing water,
drive through them very slowly.
Driving Through Flowing Water
{
CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through flowing
water, as you might at a low water crossing,
your vehicle can be carried away. As little as
six inches of flowing water can carry away
a smaller vehicle. If this happens, you and
other vehicle occupants could drown. Do not
ignore police warning signs, and otherwise be
very cautious about trying to drive through
flowing water.
Some Other Rainy Weather Tips
•
Besides slowing down, allow some extra following
distance. And be especially careful when you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared to have your
view restricted by road spray.
•
Have good tires with proper tread depth.
