e Know how to go uphill. You may want to shift down to a lower gear. The lower gearshelp cool your engine and transmission, and you can climb the hill better. e Stay in your own lane when driving on two-lane roads in hills or mountains. Don't swing wide or cut across the center of the road. Drive at speedsthat let you stay in your own lane. 0 As you go over the top of a hill, be alert. There could be something in your lane, like a stalled car or an accident. 0 You may see highway signs on mountains that warn of special problems.
