You plan a brief errand on a warm day with a child in the car. What is the safe choice?
Correct answer: Take the child with you; do not leave the child alone in the parked car.
A parked vehicle can heat dangerously. A short errand, shade or a partly open window is not a safe basis for leaving a child alone.

You are adjusting the driver's seat in a car with a frontal air bag. What seating position does NHTSA recommend?
Correct answer: At least 10 inches between your breastbone and the air-bag cover while comfortably reaching the pedals.
Leave the recommended clearance while keeping proper posture and control of the pedals. An advanced air bag does not remove the need for a safe seating position or a safety belt.

Your car is secured in a safe parking place. How can you check that its brake lights actually illuminate?
Correct answer: Have a helper press the brake pedal while you observe the rear lights.
Checking a light requires checking its operation, not just the appearance of its lens. The guide recommends a partner for observing the brake lights when the pedal is pressed.

The wiper blades move but leave broad streaks that interfere with your view. What should you do before driving in rain?
Correct answer: Replace the ineffective blades and make sure the windshield clears properly.
Wiper movement alone is not enough. The guide calls for replacement when their condition reduces driving visibility, rather than waiting for a complete mechanical failure.

There is unusual free movement in the steering wheel before the wheels begin responding. What does this suggest?
Correct answer: A steering problem that should be checked by a mechanic.
Delayed steering response can make it difficult to control the vehicle. Do not dismiss it as a harmless adjustment or try to solve it by increasing speed.

You are loading passengers and heavy luggage for a trip. Which capacity limit should you respect?
Correct answer: Both the vehicle's load limit and the tires' load limits.
A load can fit inside a vehicle while still exceeding its safe capacity. Check the applicable limits rather than using available cabin space as a weight measure.

For an accurate routine cold-tire pressure check, how long does NHTSA say the vehicle should have been parked without being driven?
Correct answer: At least three hours.
NHTSA defines cold tires for this check as tires not driven on for at least three hours. Measure with a gauge and compare with the vehicle's recommended cold pressure, including the spare as applicable.

Your tire-pressure warning light is off, and the tires look inflated. Does that remove the need for routine pressure checks?
Correct answer: No; use a gauge for regular monthly checks.
TPMS warns when a tire is significantly underinflated; it does not replace maintenance. Tires can be underinflated without looking flat, so NHTSA recommends monthly gauge checks.

A tire's tread has worn down until it is level with the built-in treadwear bars. What should you do?
Correct answer: Replace the tire rather than continue using its worn tread.
The raised wear indicators show that the usable tread has worn down. NHTSA says tires are unsafe and should be replaced at 2/32 inch of tread; extra air cannot replace missing tread.

A full-size spare has deep tread because it has sat unused for years. What is the safer conclusion about its condition?
Correct answer: It may have aged; check its age and condition before relying on it.
Rubber and other tire components change with age even when a tire is seldom used. Inspect the spare and follow the tire and vehicle makers' guidance; deep tread alone does not establish that it is safe.

You are installing replacement floor mats before a wet-weather trip. What matters most for pedal safety?
Correct answer: Use the correct fit and secure the mats as the manufacturer directs.
An improperly fitted mat can interfere with the accelerator or brake. Use mats sized for the vehicle and its retention clips according to the manufacturer's installation instructions.

A child's thick winter coat prevents the car-seat harness from fitting snugly. What should you do?
Correct answer: Use thin warm layers, secure the harness, then add a blanket over it.
Bulky coats can interfere with harness fit. NHTSA recommends thin warm layers, with a blanket or coat placed around the child after the harness is properly snug and secured.

Dense fog reduces your view. Which headlight setting is appropriate?
Correct answer: Low beams, with speed reduced to fit visibility.
High beams reflect back from fog and can worsen glare. Use low beams, slow down, and leave additional room.

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.

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.

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.

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.

A vehicle ahead raises a heavy dust cloud on a dry gravel road. What should you do?
Correct answer: Slow down, increase the gap and use low-beam headlights.
Dust can hide the roadway and other traffic. The guide recommends low beams for visibility, a lower speed and a larger following gap rather than driving into the cloud closely behind another vehicle.

You approach a narrow rural bridge with little shoulder and an oncoming vehicle nearby. What should you be prepared to do?
Correct answer: Slow down and stop if needed to let the oncoming vehicle clear.
A narrow bridge may not leave enough room for simultaneous passage. The guide recommends slowing and being prepared to stop for oncoming traffic; do not assume there is a usable shoulder.

Ahead is a bridge with an open metal-grating surface. How should you adapt?
Correct answer: Reduce speed, hold the wheel firmly and increase the gap ahead.
Open grating or steel can reduce braking and steering traction. The guide advises lower speed, a firm steering grip and more following distance rather than aggressive corrections.
