Traffic Light Offences UK: Defence & Penalties Guide

Overview

Traffic light and road sign offences cover a group of driving contraventions where a motorist is alleged to have failed to comply with a signal, a sign, or a road marking. The most common scenarios include crossing a stop line when the light is red, ignoring a 'no entry' sign, failing to give way where required, or crossing solid white lines where overtaking is prohibited.

These offences fall under the Road Traffic Act 1988 and the Traffic Signs Regulations and General Directions, which set out what each sign and signal means and the obligations they place on drivers. In most cases the offence is endorsable, meaning penalty points are added to your licence alongside a fine.

More serious examples, such as deliberately running a red light at speed, can sometimes be prosecuted as careless or dangerous driving, which carries heavier consequences. The exact approach taken by the police and courts depends on how the offence was detected, your driving history, and the circumstances on the day.

Key steps

1. Read the notice carefully. When a Notice of Intended Prosecution or a fixed penalty notice lands, check the dates, vehicle details, and the specific offence alleged. You normally have a tight window to respond, often 28 days, and missing deadlines can remove options that would otherwise be available to you.
2. Identify the driver if required. If the notice asks you to confirm who was behind the wheel, you are legally required to provide that information. Failing to name the driver is itself an offence under section 172 of the Road Traffic Act 1988 and usually carries more points than the original allegation would have done.
3. Gather your evidence. Collect anything that might support your version of events, including dashcam footage, photographs of the junction, witness details, and notes written while your memory is fresh. If a camera captured the incident, you can usually request to view the footage before deciding how to plead.
4. Consider your plea options. You can accept the fixed penalty, request a court hearing to contest the allegation, or in some cases ask to be offered a driver awareness course if one is available for that offence. Each route has different consequences for your licence, your insurance, and your finances.
5. Prepare for court if you contest it. If you plead not guilty, you will be expected to attend a magistrates' court hearing where the prosecution presents its evidence and you can put forward your defence. Organise your paperwork, think through what you want to say, and consider whether you want representation or guidance before the date.
