Traffic lights and lane control 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 ↗

Ch. 3, pp. 34–35 (Lane control signals; Traffic lights); Ch. 4, pp. 41–43 (Intersections controlled by traffic lights)

  • Lane control signals over lanes: red X = do not drive in this lane; yellow = move out into a lane with a green arrow; all lanes flashing yellow = slow down, proceed with caution; green arrow = drive in this lane.
  • Steady red: stop; after a full stop you may turn right (and left onto a one-way street, p. 41) once the intersection is clear, unless a sign prohibits.
  • Steady green: go only if the intersection is clear.
  • Steady yellow: stop before the intersection unless you cannot stop safely.
  • Flashing red: stop, treat as a stop sign. Flashing yellow: slow, caution.
  • Flashing green: pedestrian-controlled; go only if clear in your lane; scan for pedestrians (pp. 35, 42, 79).
  • Green arrow: turn in arrow direction; straight green arrow: no turns, straight only.
  • Flashing green arrow + steady green: turn or go straight. Flashing green arrow + steady red: left turn allowed, through traffic stopped.
  • Yellow arrow: advance left signal about to change; stop unless you can't safely.
  • Transit priority signal: steady white rectangular light, buses only.
  • Stale green: green for a long time; clues include traffic waiting on cross street and pedestrian signal changing to orange hand or countdown. Point of no return: past it, keep going even if it turns yellow. Fresh green: scan before moving.
  • Left turn on steady green: yield to oncoming traffic, wait for a safe gap.
  • If you are in the intersection waiting to turn left and the light turns yellow, you are legally allowed to complete the turn; watch for oncoming drivers.
  • Protected turns: while the green arrow shows, through traffic faces red. After the arrow ends with a regular green, you may still turn left but must yield to pedestrians and oncoming traffic. Some advance arrows run only in peak hours.
  • All lights flashing red: treat as a four-way stop; all flashing yellow: proceed with caution if clear (p. 41).
