Traffic lights

Information about traffic lights and signals.

General

Traffic light showing red lightRed means stop. Wait behind the stop line.

Do not go through the intersection.

 

Traffic light showing yellow lightYellow (amber) means stop. You can enter the intersection if you are so close that sudden braking might cause a crash.

 

Traffic light showing green lightGreen means proceed through the intersection carefully.

 

 

Turning arrows at traffic lights

Some traffic lights have arrows to control traffic turning right or left.

A green arrow means you can only turn in that direction.

A red arrow means traffic waiting to turn must wait behind the stop line until the arrow turns green or disappears, even if there is no traffic on the road.

Signs at traffic lights

Image showing stop sign with three black dots A STOP sign with three black dots is only seen at traffic lights. It means that if the lights are not working or are flashing yellow and you are approaching this sign, you must stop and give way to traffic as though you are at an intersection with stop signs.

 

Sign showing 'LEFT TURN ON RED PERMITTED AFTER STOPPING'This sign allows you to turn left on a red light after stopping. When turning left you must give way to all traffic approaching from the right.

Left turn on red light is only permitted at intersections where the sign has been placed.

 

 

B signals

B signals separate buses and other vehicles at some intersections with traffic lights for a safer, smoother traffic flow. To ensure B signals work properly never drive in the lanes marked buses only.

B signals are attached to the usual traffic lights. They show a white B on a black background (some traffic lights have a red, yellow and white B signal attached to them). Shortly before the usual traffic signals change to green, the B signal lights up white. All other vehicles stay while the buses may go. Buses may proceed in any direction unless signs or markings indicate otherwise. When the lights turn green other vehicles may move off.

The red and yellow B signals (or the usual red and yellow traffic lights) tell bus drivers when to stop at the intersection.
