D%ng 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 5-56. 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 carriedaway. As little as six inches of flowing water can carryaway a smaller vehicle. If this happens, you and other vehicle occupants could drown. Don't ignore police warning signs, and otherwise be very cautious about trying to drive through flowing water. 4-32
