Your car has functioning four-wheel ABS. During an emergency stop, the brake pedal pulses. What should you do?
Correct answer: Keep firm pressure on the brake pedal while steering as needed.
Pulsing can be normal ABS operation. Keep pressing the service brake; repeatedly releasing it interrupts the system’s ability to help you stop.

The surrounding pavement looks wet on a freezing morning. Why should you be especially cautious on the bridge ahead?
Correct answer: A bridge can freeze before the adjoining roadway.
Bridges lose heat readily and may ice before nearby pavement. Reduce speed and avoid sudden braking or steering.

Snow or heavy rain makes traction uncertain. What should you do with cruise control?
Correct answer: Leave it off and manage speed yourself for the conditions.
The manual advises against cruise control in bad weather. Direct, smooth speed control is important when traction changes.

A snowplow ahead creates a cloud that hides the road and its equipment. What should you do?
Correct answer: Stay well back until you have clear visibility and a safe opportunity.
Snowplows have limited visibility and equipment wider than the visible vehicle. Do not drive into the snow cloud or attempt a shoulder pass.

You leave a paved road and enter loose gravel. What should you change?
Correct answer: Slow down and make steering, acceleration and braking smoother.
Loose gravel reduces traction and can make abrupt inputs destabilize the vehicle. Slow down and allow more control margin.

Tall crops block your view of a rural intersection. You see no dust from another vehicle. What should you do?
Correct answer: Slow and approach cautiously; no dust does not prove the road is clear.
Vegetation and terrain can hide crossing traffic. The absence of a dust cloud is not reliable evidence that nobody is approaching.

A deer suddenly enters the road and you cannot avoid it by stopping in your lane. What should you avoid doing?
Correct answer: Swerving sharply into oncoming traffic or off the road.
A sudden swerve can cause a more severe crash than the animal impact. Keep control, slow as safely as possible, and watch for additional animals.

A queue beyond a railroad crossing leaves no room for your entire car. The gates are up. What should you do?
Correct answer: Wait before the tracks until you can clear them completely.
Never enter a crossing unless there is room for the entire vehicle beyond it. A signal that allows crossing does not make the tracks a waiting area.

Your engine stops while the car is moving. What should you expect while guiding it to safety?
Correct answer: Steering and braking may require more effort.
Loss of engine assistance can make steering and braking harder. Keep control and move safely off the road; do not create a steering-lock hazard.

The accelerator sticks and the car keeps pulling forward. What should you do?
Correct answer: Shift to neutral, keep your eyes on the road, and guide the car to a safe stop.
Neutral disconnects engine power from the drive wheels. Maintain steering, brake to a safe stop and shut the engine off after stopping.

Your headlights suddenly go out at night. After trying the controls, they still do not work. What should you do?
Correct answer: Use available warning lights and leave the roadway safely as soon as possible.
A car without usable headlights is unsafe to continue driving after dark. Warn other traffic and move to a safe stopping place.

Your car develops trouble but can still reach a safe pull-off. Where should you stop?
Correct answer: Well out of traffic where approaching drivers can see you.
Use warning lights and choose a visible location safely clear of traffic. A blind curve or hill can hide the disabled vehicle from approaching drivers.
