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.

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 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.

Your eyes are on the road, but an intense conversation absorbs your attention. Why is this still risky?
Correct answer: It can take mental attention away from driving even without looking away.
Distraction can be cognitive as well as visual or manual. A driver may look toward the roadway without effectively processing it.

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.

On a multilane road, you have been traveling directly beside another car for a long time. Why is it useful to adjust your position when safe?
Correct answer: It creates side space for a sudden movement or escape.
Space is needed beside the car as well as ahead. Avoiding prolonged side-by-side travel leaves more room to react if the neighboring driver moves unexpectedly.
