Pennsylvania law requires headlights to be on whenever windshield wipers are in use due to rain, snow, or other precipitation.

Answer: Slow down before entering the curve

Braking before a curve, not during it, gives you the best control on slippery surfaces.

What is the primary danger of driving through standing water at highway speed?

Answer: Hydroplaning

At highway speeds, tires cannot dispel water fast enough, causing the vehicle to ride on a film of water and lose steering control.

During a blizzard with near-zero visibility, the safest action is to:

Answer: Pull off the road, turn on hazard lights, and wait

Pulling off the road with hazard lights on alerts other drivers to your position while keeping you out of traffic.

When driving on ice, the best way to slow down is to:

Answer: Apply steady, gentle brake pressure or use engine braking

Gentle, steady braking (or engine braking in lower gear) avoids locking wheels and skidding on ice.

Which tire tread depth is the minimum recommended for safe winter driving in Pennsylvania?

Answer: 4/32 inch

Winter driving safety experts recommend at least 4/32 inch of tread depth for adequate snow and slush traction.

After driving through a deep puddle, what should you do to restore braking ability?

Lightly tapping the brakes generates friction heat that dries wet brake pads and restores stopping power.
