    3. Go straight or turn left
    4. Stop fully, then turn left only once the way is clear
  15. What does a flashing amber light at an intersection require?

    1. Go with caution after yielding
    2. Speed up to clear the area
    3. Stop completely, then go
    4. Stop and wait for green
  16. A pedestrian began crossing on a walk signal, and the signal changes to don't walk. What may the pedestrian do?

    1. Return to the starting curb

    3. Continue at the same speed
    4. Stop before the stop line
  18. You face a flashing green light. Opposing traffic has a red. What must you still do?

Traffic lights and signals: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Traffic control signals (Ch. 2 Traffic Controls)

  • Signals assign right-of-way between conflicting traffic streams at an intersection; they can be vertical or horizontal.
  • Vertical order: red top, amber middle, green bottom. Horizontal order: red left, amber middle, green right.

Steady red and steady amber

  • Steady red (a double red means the same as a single red): stop before the stop line or crosswalk on the near side; if neither, stop before entering the intersection; stay stopped unless directed or permitted.
  • Right turn on red is allowed after a full stop unless a sign prohibits it.
  • Left turn on red from a one-way street onto a one-way street is allowed after a complete stop unless a sign prohibits it.
  • A pedestrian facing a steady red must not enter unless another pedestrian signal permits.
  • Steady amber: stop before the stop line or crosswalk (or before the intersection) unless you cannot stop safely. Amber is there to clear the intersection safely. Pedestrians facing amber must not start crossing unless another pedestrian signal permits.

Steady green; steady green arrow

  • Steady green: go straight or turn right or left unless a movement is prohibited. Turning vehicles must yield to vehicles and pedestrians lawfully in the intersection.
  • A green that has been on a long time may soon turn amber; if it changes you must stop. A pedestrian signal changing from walk to don't walk is a clue the light is about to change.
  • Pedestrians facing a steady green may cross within any marked or unmarked crosswalk unless another pedestrian signal directs otherwise.
  • Steady green arrow: enter only to go in the arrow's direction.

Flashing lights

  • Flashing green arrow (left or right): you may enter and turn the way the arrow points; with a red light showing too you may turn without stopping. Can be used with a steady green. Yield to all pedestrians and vehicles in the intersection.
  • Flashing red: stop before the stop line or crosswalk (or before the intersection); go only when safe — treat like a stop sign.
  • Flashing amber: go with caution after yielding to pedestrians and vehicles lawfully in the intersection.
  • Flashing amber with a school zone, playground zone, school crossing, pedestrian crossing or other pedestrian-hazard sign: reduce speed as posted and yield to all pedestrians.

Flashing green; pedestrian signals; lane control signals

  • Flashing green: you may go straight, left or right; opposing traffic faces a red light, but you must still yield to pedestrians and vehicles lawfully in the intersection.
  • Walk signal: pedestrians may enter the crosswalk in the direction of the light.
  • Wait / don't walk signal: pedestrians must not start crossing; those who began legally may finish.
  • Lane control signals control direction of travel lane by lane, most often in reversible lanes.

Lane control signals

  • Steady red X over a lane: do not enter or stay in that lane; it will be used by oncoming traffic. Move safely to a green-arrow lane.
  • Downward-pointing green arrow: you may drive in that lane.
