When you drive overbumps, rocks, or other obstacles, your wheels can leave theground. If this happens,even with one or two wheels, you can't control thevehicle as well or at all. Because you will be onan unpaved surface, it's especially important to avoid sudden acceleration, sudden turns, orsudden braking. In away, off-road driving requires a different kind of alertness from driving on paved roads and highways. There areno road signs, posted speed limits or signal lights. You have to use your own good judgment aboutwhat is safe and what isn't. Drinking and driving can be very dangerous on any road. And this is certainly true for off-road driving. At the very time you need special alertness and driving skills,your reflexes, perceptionsand judgment can be affected by even a small amount of alcohol. You could have a serious - or even fatal -accident if you drink and drive or ride with a driverwho has been drinking. (See"Drunken Driving" in the Index.) Driving On Off-Road Hills Off-road driving oftentakes you up, down, or across a hill. Driving safely on hills requiresgood judgment and an understanding of what your vehicle can and can't do. There are some hills that simply can't be driven, no matter how well built the vehicle. Approaching a Hill When you approach ahill, you need to decide if it's one of those hills that's just too steep to climb, descend, or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small changein elevation where you can easily see all the way to the top. On a largehill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass, or shrubs. 4-15
