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.

A large vehicle ahead blocks your view of the road. How should you change your following gap?
Correct answer: Increase it so you have more room and time to respond.
A blocked view makes developing hazards harder to see. The manual calls for additional following space rather than relying only on the vehicle ahead.

What makes up total stopping distance after a driver notices a hazard?
Correct answer: The distance traveled while reacting plus the distance needed to brake.
You travel before the brakes begin slowing the car as well as during braking. Speed, road surface, tires and attention affect the space needed.

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.

You are already on an interstate and notice a car approaching the end of an entrance ramp. A lane change away from it is safe and permitted. Which action can help traffic merge smoothly?
Correct answer: Signal and move over safely to make room.
The guide recommends making room for entering vehicles when a lane change is safe. Check surrounding traffic first; cooperation does not justify an abrupt move or stopping a through lane.

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.

You need to leave a highway, but doing so now would require cutting closely in front of a tractor-trailer. What is the safer choice?
Correct answer: Let the truck continue ahead and use a safe gap or a later exit.
A truck needs its open space to slow down. Missing an exit is preferable to taking away that space with a sudden close merge.

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.

A cyclist moves away from a row of parked cars and toward the center of the lane. What may explain this position?
Correct answer: The rider is leaving room for doors that could open.
An opening door can force a cyclist into traffic or cause a crash. Give the rider room instead of treating that protective lane position as an invitation to pass closely.
