Road traffic

Running a red light

Assessing a red-light allegation requires locating the vehicle relative to the stop line when the light changed. An officer directing traffic or a lane-specific light may alter how the junction operated.

What to check in your case

Describe the signal phase, lane and observation point. Failure to comply with a red light is classified as a very serious offence.

Documents for your defence

Full notice or decision, front and back, and evidence of the date of service.
