Dash Cam Law UK: Rules, GDPR & Evidence (2026)

Overview

A dash cam is a small camera, usually mounted to the windscreen or dashboard, that continuously records the view from your vehicle while you drive. Many models also capture interior audio, GPS location, speed, and impact data. In the UK, owning and using one is lawful in most everyday situations, and insurers increasingly welcome the footage when assessing claims.

That said, 'legal to use' is not the same as 'no rules apply'. Where you place the camera is controlled by construction and use regulations, because anything that blocks your view of the road can land you with a penalty.

What you do with the footage afterwards is controlled by the UK GDPR and the Data Protection Act 2018, particularly if you share clips showing identifiable people or number plates. And if you ever want a court to rely on your recording, the footage has to meet standards of authenticity and relevance. Understanding these three layers, road safety, data, and evidence, is the key to using a dash cam responsibly.

Key steps

1. Choose a sensible mounting position. Fit the camera where it captures the road clearly but sits outside your main field of vision. A common approach is behind the rear-view mirror or low down on the passenger side of the windscreen. Cables should be tucked into trim rather than dangling across the dashboard, and nothing about the setup should obstruct airbags or wiper sweep.
2. Check the swept area of the windscreen. Under the Road Vehicles (Construction and Use) Regulations 1986, drivers must have a full view of the road and traffic ahead. If your dash cam intrudes into the area swept by the wipers directly in front of the driver, you risk a fixed penalty and points. When in doubt, move it lower or further to the passenger side.
3. Configure loop recording and storage sensibly. Most dash cams overwrite old footage automatically. Set the loop length so useful clips are not lost too quickly, and make sure the memory card is a type the manufacturer recommends. If you want to preserve a specific incident, transfer it off the card promptly so the file is not overwritten on a later drive.
4. Think about audio and passengers. Interior microphones can pick up private conversations. If you regularly carry passengers, taxi fares, colleagues, or family, let them know recording is taking place. For commercial use, such as private hire, consider a small sticker or notice inside the vehicle so people are aware before they get in.
5. Handle footage carefully after an incident. If you capture a collision or near miss, keep the original file unedited and note the date, time, and location. Share it only with people who have a genuine reason to see it, such as your insurer, the police, or your legal adviser. Avoid posting identifiable clips to social media without good reason, as this can create data protection issues.
