Light signals controlling traffic

Amber traffic light

AMBER means stop at the stop line — go on only if you have already crossed it, or are too close to pull up safely.

What does this light signal mean?

Amber requires you to stop at the line. Only two situations justify continuing: the amber appeared once you were already beyond the line, or you are close enough that braking would risk a collision from behind. That exception turns on where your vehicle sat at the instant the lamp changed, not on whether stopping is convenient. Watching the pedestrian signals across the junction gives you warning before the change arrives.
