Lesson 4 of 18 · Section 2: Safe Driving Practices

Signaling, passing and U turns

Arizona law requires a signal at least 100 feet before a turn. You may pass on the right when the other driver is turning left, but do not pass across a double solid line or within 100 feet of a crossing, bridge, tunnel or underpass.

3 questions from the Arizona practice test

  1. 1. When may a driver pass on the right because the vehicle ahead is turning?

    1. When the other driver is turning right and the shoulder is clear
    2. Whenever the other driver slows without signaling
    3. When the other driver is turning left and it is safe
    4. Only after crossing the center line
    Show answer

    When the other driver is turning left and it is safe. Arizona allows passing on the right when the other driver is turning left, but the maneuver must still be safe. Passing a vehicle turning right is not the listed condition, and a clear shoulder does not authorize leaving the paved or main roadway. Slowing without a signal gives no automatic permission to pass. Crossing the center line changes the maneuver and may create a head-on conflict. Look for the left-turn signal, confirm there is a lawful lane or marked roadway space, and proceed only with adequate room.

  2. 2. Where does the Arizona manual prohibit passing near a bridge, tunnel or underpass?

    1. Within 500 feet
    2. Within 100 feet of a bridge, tunnel or underpass where your view is blocked
    3. Within one mile
    4. Only inside the tunnel itself
    Show answer

    Within 100 feet of a bridge, tunnel or underpass where your view is blocked. You may not pass within 100 feet of a bridge, tunnel or underpass where your view is blocked. The same list bars passing on a double solid line or solid dividing line, approaching a curve or the top of a hill where you cannot see ahead to be sure of safe passing, and within 100 feet of a street crossing or a railroad crossing. The distance is 100 feet, not 500 feet or one mile, and it applies before the structure, not only inside a tunnel. Wait until your view ahead is clear.

  3. 3. A slower car ahead of you is turning left. To pass it on the right, may you drive onto the unpaved shoulder?

    1. Yes, if you signal first
    2. Yes, if the shoulder is wide and smooth
    3. Yes, if traffic behind you is heavy
    4. No, never pass on the right by driving off the paved roadway
    Show answer

    No, never pass on the right by driving off the paved roadway. Arizona allows passing on the right only in limited cases, such as when the driver ahead is turning left and it is safe. Even then, the handbook says you must never pass on the right by driving off the paved or main portion of the roadway. A wide, smooth shoulder or a turn signal does not change that rule, and neither does a line of traffic behind you. If there is no room on the pavement to the right, wait behind the turning vehicle until it clears your path.
