You and a car two lanes away both appear to be moving toward the lane between you. What should you do?
Correct answer: Delay your move until that lane is safely available.
Check the target lane and nearby lanes for vehicles moving into the same space. Signaling does not reserve a lane.

You have been watching only the rear bumper of the car ahead. What would improve your hazard detection?
Correct answer: Scan farther ahead and around the roadway while also monitoring nearby traffic.
Defensive driving requires a broad search for developing hazards. Looking beyond the nearest vehicle gives more time to plan.

Another driver makes an angry gesture after a traffic disagreement. What should you do?
Correct answer: Avoid engaging and create safe separation.
Do not turn a mistake or disagreement into a confrontation. Maintain control, avoid retaliation and separate when safe.

A driver begins moving into your occupied lane without noticing you. What is an appropriate use of your horn?
Correct answer: Give a warning to help prevent the immediate conflict.
The horn is a warning device. Use it to alert someone to danger, not to express anger or replace a safe evasive response.

A severely sleep-deprived driver drinks an energy drink and feels more alert. Does that establish that a long drive is safe?
Correct answer: No; brief microsleeps can still occur despite feeling more alert.
NHTSA warns that coffee or energy drinks alone may not be enough. A seriously sleep-deprived driver can still have microsleeps; a temporary alert feeling does not replace adequate sleep.

A truck ahead moves left as it prepares a right turn. An opening appears on its right. What should you do?
Correct answer: Stay back rather than driving into the opening.
Large trucks may need extra space to turn right. Entering the space beside the truck can put your car in the path of the trailer.

A wide farm vehicle ahead slows near an unmarked field entrance. What is the best response?
Correct answer: Stay back and allow room for an unexpected or wide turn.
Farm equipment may turn into field entrances that are difficult to see. Its width and turning path require patience and extra space.

A heavily loaded truck accelerates slowly away from a stop. How should you respond behind it?
Correct answer: Be patient and keep an adequate following gap.
Large vehicles need time to gain speed because of their weight. Pressuring the driver does not create a safe passing opportunity.

Before turning across the path of an approaching tractor-trailer, what mistake should you avoid?
Correct answer: Assuming its large appearance means it is moving slowly.
The size of a truck can mislead your estimate of its approach. If there is not a clearly safe gap, wait rather than forcing the truck to brake.

On a narrow road, a cyclist appears unaware that you are behind. If a warning is needed, how should you use your horn?
Correct answer: Give a brief, gentle tap without startling the rider.
A short warning may alert the rider to your presence. It does not create extra road width or justify intimidating the cyclist into an unsafe position.

Why should you search carefully for bicycles near the road edge at night?
Correct answer: They can be hard to see, especially in glare from approaching traffic.
Do not assume the absence of a car-sized light means the path is empty. A rider can be difficult to distinguish among headlights and roadside shadows.

A large van has just passed through an intersection where you want to turn left. Why should you check again before turning?
Correct answer: A motorcycle may have been hidden by the van.
A large vehicle can conceal a smaller road user. Look again and judge the actual gap instead of assuming the van was the last approaching vehicle.

A motorcycle ahead changes its position within the lane near gravel and potholes. What is a sensible response?
Correct answer: Give the rider space to avoid the surface hazards.
A small defect for a car can seriously affect a motorcycle's balance or traction. Expect reasonable lane-position changes and avoid crowding the rider.

Frost covers your side windows and snow covers the rear lights. What should you do before moving?
Correct answer: Clear the windows and lights so you can see and be seen.
All-around visibility and visible lights matter. Remove obstructions before driving rather than depending on speed or the defroster to solve the problem later.

Where should the lap portion of your belt fit?
Correct answer: Snugly across the hips and pelvis, not high across the abdomen.
A snug, low lap belt places forces on the pelvis. Everyone should be properly buckled before the vehicle moves.

A passenger says a belt is unnecessary for a short drive near home. What is the safest response?
Correct answer: Have the passenger buckle up before you move.
Short, familiar trips still involve crash risk. Proper restraint is a before-moving habit, not something reserved for long or fast trips.

Your car has driver-assistance features. What must you still be prepared to do?
Correct answer: Control the vehicle yourself if a feature fails or is unavailable.
Assistance technology does not replace the driver. Understand its limits and remain ready to operate the vehicle safely without it.

Your vehicle has forward-collision warning but no automatic emergency braking. An alert sounds. What should you do?
Correct answer: Assess the hazard and take the necessary braking or avoidance action.
A warning-only system alerts the driver; it does not itself brake the vehicle. Know which functions your own vehicle actually provides.

Mud or snow covers a sensor used by your assistance system. What should you do?
Correct answer: Clean it as directed and do not rely on the system to detect every hazard.
Obstructed sensors can limit assistance features. Follow the owner’s instructions and keep checking the surroundings yourself.

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.
