Understanding Traffic Lights
Traffic lights control the flow of traffic and pedestrians. Understanding all the signals keeps you safe and legal.
Standard Traffic Light Sequence
What Each Light Means
Red Light - STOP
Come to a complete stop. Wait behind the stop line or before the intersection.
Yellow/Amber Light - CAUTION
Stop if you can do so safely. If you're too close to stop safely, proceed through the intersection.
Green Light - PROCEED
Proceed if the intersection is clear. Give way to pedestrians and vehicles already in the intersection.
Green Arrow Signals
When you see a green arrow:
- • Green arrow pointing left: You can turn left even if there's a red light (after giving way)
- • Green arrow pointing right: Protected turn - oncoming traffic is stopped
- • No green arrow: You must wait for the green light like everyone else
Pedestrian Signals
WALK
Pedestrians can cross
DON'T WALK
Pedestrians must wait
Flashing Yellow Lights
Flashing Yellow Traffic Light:
- • Proceed with caution
- • Slow down and be prepared to stop
- • Give way to all traffic and pedestrians
Often seen at pedestrian crossings at night or off-peak hours.
Red Light Cameras
📸 What You Need to Know:
- • Cameras capture vehicles entering on red
- • Fine: ~$472 + 3 demerit points in NSW
- • If caught in the intersection on yellow turning red, you're likely fine
- • Cameras typically flash twice (front and rear)
Did You Know?
Traffic lights have sensors buried in the road to detect vehicles. If you're waiting at a red light with no other cars around:
- • Pull forward to the stop line — sensors are usually placed there
- • Stay centered in your lane — sensors detect metal in your car
- • Small cars and motorcycles sometimes don't trigger older sensors
- • If it still won't change, check for a pedestrian push button
Pro Tip:
When the light turns green, don't rush through immediately. Take a moment to check that vehicles aren't running the red light from the cross street. It's saved many lives.
