Weather, Visibility & EmergenciesStandalone practice
You normally drive 50 mph on a rural highway. Today the road is covered with hard-packed snow. Which speed follows the handbook's advice?
Correct answer: Below 25 mph, which is more than half below your normal speed
Why
Hard-packed snow increases the danger of a skid, and bridges, overpasses and shady spots often freeze first. Speed up slowly, test your steering and brakes gently, and allow at least three times the normal distance to stop. Keep extra space from the vehicle ahead, because you cannot start, stop or turn quickly on snow and ice.
