Module 15 of 26

Traffic signals

Robots, and the three situations that trip people up at them: an amber you are already too close to stop for, a filter arrow lit beside a red, and a dead intersection in a power cut.

Three colours are the easy part. What the test asks about is the amber, the arrow against a red main light, and what to do when the lamps are dead.

Amber is not 'hurry'

Amber means stop, unless you are so close that stopping would be dangerous — because the vehicle behind you would run into you, or because you are already past the stop line.

It is not permission to accelerate through. The question that catches people phrases it as though amber were a warning to speed up, and it is the opposite: it is a warning to stop.

Where people lose the markReading amber as the last of the green rather than the first of the red.
