Rules to remember10 key right-of-way, turns and intersections rulesShow the rules
  1. The rules show who should yield, but no one should assume they automatically have the right-of-way. (p. 31)

  3. Always turn right from the right-most portion of the lane and avoid swinging wide to the left. (p. 38)

  7. Traffic in a roundabout moves one way in a counterclockwise direction. (p. 39)
  8. As you approach your exit, turn on your right turn signal, and yield to pedestrians and bicycles when exiting. (p. 40)
  9. Quickly tap the brake pedal 3 or 4 times to warn drivers behind you that you are about to slow down. (p. 56)
