4-16 Driving Your Vehicle Surface Obstacles: Unseen or hidden obstacles can be hazardous. A rock, log, hole, rut, or bump can startle you if you are not prepared for them. Often these obstacles are hidden by grass, bushes, snow, or even the rise and fall of the terrain itself. Some things to consider: When driving over bumps, rocks, or other obstacles, the wheels can leave the ground. If this happens, even with one or two wheels, you cannot control the vehicle as well or at all. Because you will be on an unpaved surface, it is especially important to avoid sudden acceleration, sudden turns, or sudden braking. Off-roading requires a different kind of alertness from driving on paved roads and highways. There are no road signs, posted speed limits, or signal lights. Use good judgment about what is safe and what is not. Scanning the Terrain Off-road driving can take you over many different kinds of terrain. Be familiar with the terrain and its many different features. Surface Conditions: Off-roading surfaces can be hard-packed dirt, gravel, rocks, grass, sand, mud, snow, or ice. Each of these surfaces affects the vehicle's steering, acceleration, and braking in different ways. Depending on the surface, slipping, sliding, wheel spinning, delayed acceleration, poor traction, and longer braking distances can occur. • Is the path ahead clear? • Will the surface texture change abruptly up ahead? • Does the travel take you uphill or downhill? • Will you have to stop suddenly or change direction quickly? When driving over obstacles or rough terrain, keep a firm grip on the steering wheel. Ruts, troughs, or other surface features can jerk the wheel out of your hands.
