HPT Night and Weather Hazards 2

Question 1

What is the recommended response when oncoming headlights cause temporary blindness at night?

Accepted Answer

Slow down, look toward the left edge of the road, and avoid staring at the lights

Answer

Looking toward the left edge reduces glare impact while allowing you to maintain lane position until vision recovers.

Question 2

How does strong crosswind affect hazard perception on exposed roads?

Accepted Answer

Vehicles can be pushed across lane lines, creating unexpected hazard positions

Answer

Strong crosswinds can push vehicles laterally across lanes without driver input, creating sudden and unexpected hazard positions.

Question 3

Why do snowy conditions present unique hazards compared to wet roads?

Accepted Answer

Snow can mask road markings and signs while dramatically reducing grip

Answer

Snow hides lane markings and signs while also reducing tire grip to a fraction of dry-road levels, making hazard identification and response much harder.

Question 4

A driver is in dense fog with visibility under 100 meters. What rule applies to their headlight use?

Accepted Answer

Rear fog lights should be used when visibility drops below 100 meters

Answer

US federal and most state regulations recommend using rear fog lights when visibility falls below 100 meters to alert following drivers.

Question 5

How does driving into heavy snow affect reaction times and hazard management?

Accepted Answer

Snow lengthens stopping distances and reduces hazard visibility simultaneously

Answer

Snow simultaneously reduces tire-road grip (extending stopping distance) and visibility, compounding hazard management difficulty.
