EVOC Night Driving & Low Visibility Operations Flashcards

What additional stopping distance should a driver expect on wet pavement at night compared to dry daytime conditions?

Answer: Approximately double the normal stopping distance

Wet pavement reduces tire-road friction significantly, and night conditions compound the hazard by limiting early hazard detection.

When driving through a low-visibility smoke condition near a structure fire, the EVOC-trained driver should:

Answer: Stop the vehicle before entering smoke of unknown density

Smoke density is unpredictable and may conceal personnel, hose lines, or debris, so stopping before entry is the safest practice.

Night operations increase driver fatigue due to:

Answer: Circadian rhythm disruption and reduced visual stimulation

The body's natural sleep cycle and the monotony of reduced visual input during night driving accelerate mental fatigue and impair reaction time.

What is the recommended technique for scanning the road ahead during emergency night driving?

Answer: Use a systematic side-to-side sweep rather than fixed-center stare

A systematic scanning pattern prevents tunnel vision and ensures peripheral hazards — animals, pedestrians, and stopped vehicles — are detected early.

When another vehicle's headlights create glare while approaching at night, the EVOC best practice is to:

Answer: Look toward the right edge of the road to avoid direct glare

Averting your gaze to the road edge avoids the blinding effect of oncoming headlights while still tracking your lane position.

Black ice is most commonly found at night in which locations?

Answer: Bridges, overpasses, and shaded roadway sections

Bridges and shaded areas lose heat faster than surrounding pavement, causing water to freeze first and forming nearly invisible black ice.
