You approach a snowplow working along the road. What should you do?
Correct answer: Stay back and avoid traveling beside it.

Snow surrounds a stranded car. Before occasionally running its engine for warmth, what important hazard must be addressed?
Correct answer: Snow blocking the exhaust pipe can allow carbon monoxide to build up.
Keep snow away from the exhaust and do not run the engine continuously. Exhaust gases can be lethal; an enclosed area or blocked outlet is especially dangerous.

Where should you look for the recommended cold tire pressure for your vehicle?
Correct answer: The vehicle's door-frame label or owner's manual.
Use the vehicle manufacturer’s recommendation, not the tire sidewall’s maximum-pressure figure. Cold weather can lower tire pressure, so inspect it regularly.

Weather reports warn that roads on a non-essential trip are in poor condition. What is a reasonable safety choice?

A car has forward collision warning but no automatic braking feature. Its warning sounds. What must the driver understand?
Correct answer: The warning alone does not apply the brakes.
Forward collision warning alerts the driver to danger. It is not itself a braking system; the driver must assess the situation and act.

A lane-departure warning sounds as a vehicle drifts. Does that warning feature by itself steer the vehicle back?
Correct answer: No; it alerts the driver without steering intervention.
A warning system and a lane-keeping intervention are different functions. Do not wait for a warning-only feature to correct your steering.

What is a realistic understanding of automatic emergency braking?
Correct answer: It may prevent a crash or reduce its severity, but is not a guarantee.

A Level 2 system assists with steering and speed at the same time. Who remains responsible for monitoring the road and driving?
Correct answer: The driver, who must stay attentive and engaged.

What does adaptive cruise control ordinarily adjust to maintain a selected gap from a vehicle ahead?

You switch to a car with unfamiliar driver-assistance feature names. What should you do before relying on them?
Correct answer: Read its manual to learn which functions it has and their limitations.
