Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include:

• Keep the vehicle serviced and in good shape.

• Check all fluid levels and brakes, tires, cooling system, and transmission.

• Shift to a lower gear when going down steep or long hills.

• Stay in your own lane. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane.

• Be alert on top of hills, something could be in your lane (stalled car, accident).

• Pay attention to special road signs (falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.
