Missouri driving lesson · Special Driving Conditions
Winter driving and wet pavement
A 3-minute lesson from the Missouri course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Snow, ice and rain all reduce traction, so starting, steering and stopping all take longer. The handbook's reminder: "Ice and Snow... Take it SLOW!"
Know the rule
Before driving in winter, clean all snow and ice off your windows, headlights and taillights, however short the trip. Make sure the wipers and defroster work.
If your tires spin, try rocking backward and forward a few times; if that fails, spread salt, sand or cat litter around the wheels. Never let anyone stand in line with your wheels.
Brake gently and smoothly; never slam the brakes. On very slippery surfaces, pump the brakes gently several times. With ABS, follow your owner's manual.
When rain starts, water mixes with dust and oil into a slick, greasy film; fallen leaves get slippery too. Slow down, leave more space, and expect longer stops.
Freezing drizzle fell overnight, and the highway looks wet but clear. Approaching an overpass, ease off: it can be icy even when the road before it isn't. Keep 8 to 10 seconds behind the car ahead.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
