Off-Road Driving with Your Four-Wheel-Drive Vehicle This off-road guide is for vehicles that have four-wheel drive. Also, see Braking on page 4-6. If your vehicle doesn't have four-wheel drive, you shouldn't drive off-road unless you're on a level, solid surface. Off-road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself. "Off-roading" means you've left the great North American road system behind. Traffic lanes aren't marked. Curves aren't banked. There are no road signs. Surfaces can be slippery, rough, uphill or downhill. In short, you've gone right back to nature. Off-road driving involves some new skills. And that's why it's very important that you read this guide. You'll find many driving tips and suggestions. These will help make your off-road driving safer and more enjoyable.
