A 3-minute lesson from the Wisconsin course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Bad weather cuts your traction and your view. The safest choice is often not to drive; if you must, slow down, stay smooth, and know what to do if your tires lose their grip.
Know the rule
Plan ahead: stay home if the roads look icy or unsafe, and check your vehicle before leaving.
In reduced visibility, vehicles may appear to move slower than they actually are. At night it's harder to judge the distance and speed of oncoming traffic.
On slippery, icy, snow-covered or flooded roads it's best not to drive. If you do, slow down, stay alert, and avoid rapid braking or sudden sharp turns.
It's 33°F and drizzling. The road feels fine, but ahead is a shaded bridge. Slow down before you reach it, and avoid rapid braking or sharp turns on it: bridges freeze before the rest of the road.
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.
In reduced visibility, other vehicles may appear to be:
Moving faster than they actually are
The same speed, visibility doesn't affect perception
Stopped, even when moving
Moving slower than they actually are
Answer: Moving slower than they actually are
In reduced visibility, vehicles may appear to be moving slower than they actually are.
