Weather & Hazardous Conditions Flashcards

When is it appropriate to use hazard lights (emergency flashers) while driving?

Answer: Only when your vehicle is stopped or moving very slowly due to an emergency

Hazard lights signal a genuine emergency or dangerous situation, not routine driving in poor weather.

What is the safest speed adjustment when driving in heavy rain on a highway?

Answer: Reduce speed by at least 5-10 mph below the posted limit and adjust further if conditions worsen

Reducing speed lowers hydroplaning risk and provides more reaction time in reduced-visibility conditions.

If you begin to hydroplane, what is the correct immediate response?

Answer: Ease off the accelerator smoothly and hold the steering wheel straight

Gently reducing speed allows tires to regain contact with the road without causing a spin.

Which factor most increases the risk of hydroplaning?

Answer: Driving at high speeds on wet roads with worn tires

Worn tires cannot channel water away effectively, and high speeds prevent tires from maintaining road contact.

What precaution should drivers take in areas prone to sudden flash flooding?

Answer: Monitor weather alerts and never attempt to cross flowing or unknown-depth water

Flash floods can rise within minutes, and water depth cannot be accurately judged visually from a vehicle.

How does extreme heat affect road surfaces and driving safety?

Answer: Extreme heat can cause pavement buckling, tire blowouts, and brake fade

High temperatures can cause asphalt to buckle, weaken tire structure leading to blowouts, and reduce brake effectiveness.

When preparing to drive in winter conditions, which vehicle check is most critical?

Answer: Checking tire tread depth, tire pressure, battery, brakes, and wiper condition

Cold weather stresses tires, batteries, and brakes while reduced visibility demands functional wipers.
