Key points
- 'Response to signals: traffic lights' is on the DVSA's list of the most common reasons for failing.
- Learners either brake too hard for every amber or speed up to 'make it'.
- Drill: Stale green thinking.
- Your DriveSQ Student Portal tracks this skill lesson by lesson.
Traffic lights are simple — until there are three sets in 200 metres, a filter arrow, a box junction and a bus lane. Responding wrongly to lights is a regular DVSA top-10 fault.
What the examiner is looking for
Stopping at red, not going on amber when you could stop safely, moving when green only if it's safe, obeying filter arrows, and stopping at the first white line where there's an advanced stop line for cyclists.
What it looks like on test
- Going through an amber when you could have stopped.
- Stopping across the cyclists' box at an advanced stop line.
- Moving on green without checking the junction is clear.
- Missing a filter arrow, or following one meant for another lane.
- Waiting at a green light for no reason.
Why it happens
Learners either brake too hard for every amber or speed up to 'make it'. The fix is approaching at a speed where the decision is easy.
How to fix it: drills we use
Stale green thinking
If a green has been showing for a while, expect it to change — be ready to stop.
Point of no return
Pick the point where you'd go if it turned amber now. Before it: stop. After it: go.
Lane-arrow reading
Read the lane arrows and filter lights well before the stop line.
Where it catches learners in Greater Manchester

Self-check before your test
Can you tick all of these?
Be honest — if not, tell your instructor and practise it on your next lesson.
In the DriveSQ Student Portal your instructor marks "Response to signals: traffic lights" as its own skill after each lesson, so you can watch it move from "introduced" to "independent" before you book.
