Traffic lights and pedestrian 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 lights

  • Green: turn left, go straight or turn right after yielding to vehicles and pedestrians already in the intersection; yield to pedestrians when turning.
  • Yellow: red is coming; stop if you can do so safely, otherwise go with caution.
  • Red: full stop (stop line, else crosswalk marked or not, else sidewalk edge, else intersection edge). Right on red allowed after a full stop when clear unless a sign forbids it. Left on red only one-way onto one-way, after stopping.
  • Advance green (flashing green, or green arrow with green light): may turn left, go straight or right; oncoming traffic faces red. Pedestrians may not cross on it unless a pedestrian signal says so.
  • Simultaneous left turn (green arrow with red light): opposite traffic may also be turning left. Yellow arrow after it: do not start the turn; stop if safe. If light turns red while you are in the intersection, complete the turn when safe.
  • Fully protected left turn: separate left-turn signals; you may not start turning left after through traffic gets green.
  • Flashing red: full stop, go when safe. Flashing yellow: caution.
  • Blank lights (power failure): yield to vehicles in the intersection and from the right; treat as all-way stop.
  • Transit priority signal: white vertical bar on dark round signal; transit vehicles go while conflicting traffic has red.
  • Beacons: flashing red = stop; flashing yellow = caution.

Pedestrian signals

  • Walk = white walking symbol. Flashing or steady orange hand = do not start crossing.
  • Pedestrians already crossing keep the right-of-way over vehicles.
  • Intersection pedestrian signal: lights on main road only; stop signs on the smaller crossroad; push buttons.
