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
•
Turn on your low-beam headlamps — not just
your parking lamps — to help make you more
visible to others.
•
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. See
Tires on page 550.
