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.

You recognize your turn too late to slow and position safely. What is the best response?

Plan and position for turns in advance. A missed turn is safer to correct later than with a sudden sharp maneuver.

You need to move across two lanes. How should you carry out the move?
Correct answer: Check, signal and complete one lane change before assessing the next.
Make lane changes individually, checking the space and yielding to traffic in each lane. A gap in the first lane does not prove the next lane is clear.

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 lawfully passed a car on a two-lane road. What helps you judge when there is enough room to return?
Correct answer: See the front of the passed car in your rearview mirror, then return safely.
Leave room rather than cutting off the passed vehicle. Seeing its front in the rearview mirror helps establish clearance before returning safely.

Before reversing from a driveway, your camera shows no vehicle directly behind. What else should you do?
Correct answer: Check around and behind the car, turn to look, and keep checking while backing slowly.
Mirrors and cameras do not show everything and can distort distance. Look directly, check blind spots and keep the backing speed low.

An entrance ramp provides room to accelerate before merging. What should you normally do?
Correct answer: Use it to approach traffic speed and merge into a safe gap.
The acceleration lane helps you join smoothly. Look for a safe gap and avoid stopping unless conditions make it necessary.
