Weather and Hazardous Conditions Flashcards

Why should you slow down before reaching a bridge or overpass in freezing weather?

Answer: Bridges freeze before the rest of the road because cold air circulates above and below them

Cold air surrounds a bridge deck on both sides, so it loses heat faster and ices over before regular road surfaces.

You encounter a moose standing on the roadway at dusk during a snowstorm. What should you do?

Answer: Slow down or stop and wait for it to leave; do not swerve suddenly

Moose are unpredictable and heavy enough to cause fatal crashes, so slow down or stop rather than swerving or provoking them.

In whiteout conditions where visibility drops to near zero, what is the safest action?

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

When you cannot see, get fully off the roadway and make your vehicle visible rather than stopping in a travel lane or tailgating.

How does driving during long winter darkness in Alaska affect your driving?

Answer: Reduced visibility and fatigue require slower speeds and extra alertness

Extended darkness limits visibility and increases fatigue, so drivers must slow down and stay especially alert.

What is the safest way to brake on a slippery road if your vehicle has antilock brakes (ABS)?

Answer: Apply firm, steady pressure and let the ABS pulse

With ABS you should press the pedal firmly and hold it, allowing the system to prevent wheel lockup automatically.

When your windshield begins to fog or frost over while driving, what should you do?

Answer: Use the defroster and, if needed, pull over until the glass is clear

You must have a fully clear windshield, so use the defroster and stop driving if you cannot see adequately.

Which tires or traction devices help most on Alaska's icy winter roads?

Answer: Studded tires or chains when conditions and season allow

Studded tires or chains provide the extra grip needed on ice, and Alaska allows studs during designated winter months.
