You need to recognise road signs, markings, traffic lights and lawful signals early enough to respond safely.
The correct response may involve speed, lane choice, stopping, giving way or following directions from police, school crossing patrols or other authorised controllers.
These examples are for understanding and practice; they are not a promise that a particular mistake will always receive a particular grade.
Seeing a sign but acting too late to change lane or speed safely.
Moving on a green light without first checking that the junction is clear.
