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.

A car approaching from your left has its right-turn signal on. You are waiting to enter its road. What is safest?
Correct answer: Wait until its movement confirms the turn and your path is clear.
An indicator can be left on or activated early. Confirm the vehicle is actually turning before relying on that opening.

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.

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?

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.
