A bicyclist enters your path when the bicyclist should have yielded. You have room to slow safely. What is your responsibility?
Correct answer: Slow or stop as needed to prevent a collision.
Right-of-way rules do not excuse a driver from avoiding a collision. Take a safe defensive action even when another road user makes the mistake.

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.

A driver is following too closely. What is the safest response when an opportunity develops?
Correct answer: Allow the driver to pass safely and keep your own actions predictable.
Avoid escalating a tailgating conflict. Let the driver go by safely rather than brake-checking or speeding.

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 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.
