Driving at Night and in Bad Weather: Safe Driving & Sharing the Road

Night, drive within the range of your headlights, keep the windshield and lights clean, and dim your high beams for oncoming and followed traffic.
Rain, roads are most slippery in the first minutes of rain, when water lifts oil and dust off the surface. Slow down and watch for hydroplaning.
Snow and ice, slow down, brake gently and early, and leave far more space. A heavy truck that loses traction is very hard to recover.
Fog, slow down and use low beams; high beams reflect off the fog and reduce visibility further.

Common mistake: using high beams in fog. They make it harder to see, not easier.

Recall: When is a wet road most slippery? Which headlights should you use in fog?
