HPT Night and Weather Hazards 1

Question 1

Why does driving at night increase the risk associated with hazard perception?

Accepted Answer

Reduced visibility means hazards are seen later, leaving less reaction time

Answer

At night, hazards appear later within a driver's visual field, significantly reducing the time available to react safely.

Question 2

How does heavy rain affect your ability to perceive hazards while driving?

Accepted Answer

Rain reduces visibility and road noise from rain can mask other hazard cues

Answer

Heavy rain reduces forward visibility through windshields and creates noise that can mask pedestrian or vehicle sounds.

Question 3

What additional hazard does fog create beyond simply reducing visibility?

Accepted Answer

Drivers may misjudge their speed and following distances in fog

Answer

Fog distorts distance and speed perception, causing drivers to feel they are driving slower than they actually are.

Question 4

When driving into a low sun, what is the primary hazard perception challenge?

Accepted Answer

Glare can temporarily blind the driver to hazards ahead

Answer

Sun glare can completely blind a driver to hazards, pedestrians, and traffic signals directly in the sun's path.

Question 5

How does driving at dawn or dusk create a specific hazard perception challenge?

Accepted Answer

Low ambient light and potential sun glare make pedestrians and cyclists harder to see

Answer

At dawn and dusk, ambient light levels make it difficult to see unlit or dark-clothed pedestrians and cyclists while sun glare may also be present.
