A motorcycle is using the left portion of its lane. May you squeeze your car past within the same lane?
Correct answer: No; give the motorcycle the full lane width.

You are so close behind a truck that you cannot see its driver in the side mirrors. What should you do?
Correct answer: Increase your following space and improve your view.

A distant tractor-trailer appears to be moving slowly as you prepare to cross its road. What is the important caution?

A vehicle ahead has stopped for a pedestrian crossing the road. What should you do?

Before turning right from a driveway onto a road, why should you look right as well as left?
Correct answer: A bicyclist may approach from the right on the road or sidewalk.

You park facing uphill on the right side of a road with no curb. Which way should the front wheels point?

Before moving out of a roadside parking space, what should you do?

Before changing to the left lane to pass, what should supplement your mirror checks?
Correct answer: A brief look over your left shoulder for the blind spot.

Compared with an alert driver in a well-maintained car, what can tiredness and poor brakes do to stopping needs?
