SNOW AND ICE DRIVING
1. Accelerate slowly to avoid spinning the tires.
2. Drive at slower speeds.
3. Give signals sooner.
4. Lightly pump brakes once or twice to give early warning of intention to stop.
This will also help to avoid skidding.
5. Maintain at least double the normal distance from the vehicle ahead.
6. Keep windshields, windows, mirrors, headlamps, stoplamps, and body lamps clean
and free of snow and ice. Use defrosters and fans to help keep glass free of snow
and ice.
7. Descend moderate grades in the gear normally used to ascend the same grade. On
steep or very slippery grades, lock differential, use at least one gear lower, and
activate engine retarder system.
8. After driving through slush or water, drive slowly and test the brakes. Continue
driving slowly, maintaining moderate pressure on the service brake pedal to create
a slight drag. Resume normal speed when brakes are dry and operating properly.
