TS10 — Failing to Comply with Traffic Light Signals

Red light camera tickets are more challengeable than most drivers assume. Get the evidence checked.

TS10 is the code for failing to comply with traffic light signals — in practice, almost always a red light camera at a junction. The camera fires when a vehicle crosses the stop line after the signal has turned red, and the standard outcome is a £100 fixed penalty with 3 points.

TS10 evidence is more contestable than plain speeding: the case turns on precisely when the vehicle crossed the line relative to the light phase, whether the stop line and signals met specification, and what the timing photos actually show. Junctions with short amber phases or obscured signals generate successful challenges every year.

How TS10 cases are decided

  1. The offence is crossing the stop line after red — not being in the junction when it changes.
  2. Standard outcome: £100 fixed penalty and 3 points.
  3. Evidence is a pair of timed photos showing the vehicle relative to the stop line.
  4. Amber must be correctly timed (about 3 seconds at typical urban speeds) — faults support a challenge.
  5. Some forces offer an awareness course for signal offences instead of points.

The light changed as I crossed — am I guilty?

If your wheels crossed the stop line before red, no offence was committed. The camera’s paired photos and timings establish this — which is why having them reviewed before accepting the penalty is worthwhile.

I stopped just past the line — will I still be prosecuted?

Stopping immediately after the line, without proceeding through the junction, is frequently filtered out or worth challenging — the photos will show the vehicle stationary. Don’t just pay without looking at the evidence.

Does a TS10 affect insurance like a speeding code?

Yes — it’s a licence endorsement disclosed the same way and stays on your record for 4 years. Insurers price it similarly to a single speeding offence.
