9-12 Driving and Operating Driving Uphill Once you decide it is safe to drive up the hill: . . Consider this as you approach a hill: . Is there a constant incline, or does the hill get sharply steeper in places? Is there good traction on the hillside, or will the surface cause tire slipping? Is there a straight path up or down the hill so you will not have to make turning maneuvers? Are there obstructions on the hill that can block your path, such as boulders, trees, logs, or ruts? What is beyond the hill? Is there a cliff, an embankment, a drop-off, a fence? Get out and walk the hill if you do not know. It is the smart way to find out. Is the hill simply too rough? Steep hills often have ruts, gullies, troughs, and exposed rocks because they are more susceptible to the effects of erosion. Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route. Ease up on the speed as you approach the top of the hill. Attach a flag to the vehicle to be more visible to approaching traffic on trails or hills. Sound the horn as you approach the top of the hill to let opposing traffic know you are there. Use headlamps even during the day to make the vehicle more visible to oncoming traffic. . Use a low gear and get a firm grip on the steering wheel. Get a smooth start up the hill and try to maintain speed. Not using more power than needed can avoid spinning the wheels or sliding. . . . . . . { WARNING Turning or driving across steep hills can be dangerous. You could lose traction, slide sideways, and possibly roll over. You could be seriously injured or killed. When driving up hills, always try to go straight up. . . .
