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 ↗

Green light

  • Steady green: you may turn left, go straight or turn right, but first yield to vehicles and pedestrians already in the intersection.
  • When turning left or right on green, yield to pedestrians crossing.

Yellow light

  • Yellow (amber) warns that red is coming next.
  • Stop if you can do it safely; if you can't, continue with caution.

Red light

  • Red = complete stop. Where to stop, in order: marked stop line → crosswalk (marked or unmarked) → edge of sidewalk → edge of intersection.
  • Move only once the light is green and the intersection is clear.
  • Right on red: allowed unless a sign forbids it, only after a complete stop and once the way is clear.
  • Left on red: allowed only from a one-way road onto a one-way road, after a complete stop and once the way is clear.

Advance green light or arrow

  • Flashing green, or a left green arrow together with a green light = advance green: left, straight or right from the proper lane.
  • Called "advance" because oncoming traffic is still held on red.
  • Pedestrians may not cross on a flashing green unless a pedestrian signal allows it.

Simultaneous left turn

  • Left green arrow shown with a red light: turn left from the left-turn lane; opposite-direction left-turners may be turning at the same time (they also have the arrow).
  • Yellow arrow after the green arrow: a green is about to appear for traffic in one or both directions. Don't start the turn; stop if safe, otherwise finish with caution.
  • Left turns are still allowed on the following green, but only when clear of traffic and pedestrians. If the light goes red while you are in the intersection, complete the turn when safe.
  • Pedestrians may not cross on a left-turn green arrow unless a pedestrian signal allows it.

Transit priority signals

  • Drivers and pedestrians yield to public transit vehicles at a transit priority signal.
  • Look: round signal mounted above a regular signal; white vertical bar on a dark background.
  • Lets transit go straight, turn right or turn left while all conflicting traffic faces red.

Fully protected left turn

  • Separate signals for left-turners vs through/right-turning traffic.
  • Left green arrow: left-turn lane may go; through and right-turn traffic usually sees red; opposite left-turners may also be turning.
  • Sequence for left-turners only: green arrow → yellow → red. Through/right traffic then gets green or straight/right green arrows.
  • You may not start a left turn once the through traffic gets its green.
  • If it turns yellow while you are in the intersection, complete the turn with caution.

Flashing red light / Flashing yellow light

  • Flashing red light: complete stop, proceed only when safe.
  • Flashing yellow light: caution approaching and through the intersection (no stop required).

Blank traffic lights

  • Power loss = signals dark. Yield to vehicles in the intersection and to vehicles entering from your right; go cautiously; treat as an all-way stop.

Traffic beacons

  • A beacon is a single flashing light, hung over an intersection, placed over signs, or on obstacles in the road.
  • Flashing red beacon (over an intersection or a stop sign): complete stop, proceed when safe.
  • Flashing yellow beacon (over an intersection, over a warning sign, or on an obstruction): drive with caution.

Pedestrian signals

  • Walk = white walking-person symbol. Don't start crossing = orange hand, flashing or steady.
  • Pedestrian with a walk signal may cross in that direction and has right-of-way over all vehicles while crossing.
  • If the hand appears after they started, they should get to a safe area quickly; they still keep right-of-way over vehicles while crossing.
  • Intersection with traffic lights but no pedestrian signals: pedestrians may cross on a green light, but not on a flashing green or a left-turn green arrow.

Intersection pedestrian signals

  • Where push-buttons exist, the pedestrian must press one to get the walk signal.
  • Pedestrian signals give more crossing time than regular traffic lights.
  • Intersection pedestrian signal: used on a busy main road; has one or more crosswalks, walk/don't walk signals, push-buttons, and traffic lights on the main road only. Stop signs control the smaller crossroad.
