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.
See Tires on page 439.
