Traffic lights and signals: key rules to remember

Driver's Guide (Spring 2026), Ch. 2 Traffic Control, pp. 22–25
- Vertical signal order: red top, yellow centre, green bottom. Horizontal: red left, yellow centre, green right.
- Solid red: stop before stop line; if none, before crosswalk; if none, before intersection. Stay stopped until green unless turning right after stopping.
- Double red = same meaning as single red.
- Right on red allowed unless a sign prohibits; full stop first, yield to traffic and pedestrians.
- Left on red only from a one-way street onto a one-way street, after a full stop, unless prohibited.
- Solid yellow: stop before the line/crosswalk unless you are too close to stop safely; if already in the intersection, clear it.
- Solid green: proceed; yield to oncoming traffic when turning left and to pedestrians when turning.
- Stale green = green for a while; check pedestrian signal — WALK means it will stay green, DON'T WALK means be ready to stop.
- Green arrow + green light: go in arrow direction without yielding; other directions allowed when safe/legal.
- Green arrow + red light: proceed only in arrow direction without stopping.
- Flashing red: stop, then go when safe — treated like a stop sign. All directions flashing red = four-way stop.
- Flashing yellow: proceed with caution, yielding to pedestrians and vehicles in the intersection.
- Flashing green (Alberta): you may go straight, turn left or turn right without stopping; opposing traffic faces red; still yield to pedestrians/vehicles lawfully in the intersection.
- Pedestrian WALK: may enter crosswalk when safe. DON'T WALK: must not enter; those already crossing may finish. Some have countdown timers.
- Yellow flashing lights on school, playground, school crossing or pedestrian crossing signs: slow to max 30 km/h and yield/stop for pedestrians.
- Where no pedestrian signals: pedestrians follow the vehicle light they face (red don't enter; yellow clear/don't enter; green cross).
- Lane reversal signals: red X = do not enter or stay in that lane (oncoming traffic uses it); downward green arrow = you may travel in that lane.
- A peace officer's directions override signs and signals.
- Warning sign with flashing yellow lights before signals: prepare to stop; the light is changing or red.
