When driving down a long or steep hill, you should:

Check your mirrors for vehicles approaching quickly when you are traveling down hills or mountains. Vehicles often build up speed when being driven down a steep grade. Be especially alert to large trucks and buses that may be going too fast.

• Check your mirrors for speeding traffic behind you.
• Assume all traffic is maintaining a consistent speed.
• Watch over your shoulder for traffic behind you.
• Hold down your brake pedal to control traffic speeds.
