What it means
Prepare to stop vehicle behind line and remain stationary until a green signal is displayed. Steady amber: slow down and prepare to stop. Do not enter the intersection unless you are already so close that stopping would be unsafe.
What to do
- Stop behind the line unless stopping safely is impossible.
- Never accelerate to beat the red.
In the K53 test
Amber commands a stop where one is safely possible. Speeding up on amber is both the test trap and the crash pattern.
Where you will see it
At a traffic signal face controlling the approach.
