Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: • A hill that can be driven straight up or down may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base - the distance from the front wheels to the rear wheels - reduces the likelihood the vehicle will tumble end over end. But when you drive across an incline, the much more narrow track width - the distance between the left and right wheels - may not prevent the vehicle from tilting and rolling over. Also, driving across an incline puts more weight on the downhill wheels. This could cause a downhill slide or a rollover. • Surface conditions can be a problem when you drive across a hill. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it - a rock, a rut, etc. - and roll over. • Hidden obstacles can make the steepness of the incline even worse. If you drive across a rock with the uphill wheels, or if the downhill wheels drop into a rut or depression, your vehicle can tilt even more. 385
