Prosecution based solely on dashcam footage

This is a good question and one that comes up increasingly often as dashcam use has become widespread.

Short answer:

Yes, the police can and do prosecute based solely or primarily on dashcam footage provided by another road user. There is no legal rule that requires the police to have witnessed an offence themselves in order to bring a prosecution.

Legal position:

Dashcam footage is admissible as evidence in criminal proceedings. It is treated as real evidence, much like CCTV or body-worn camera footage. The prosecution does not need a police officer to have been present at the time of the alleged offence.

Many police forces in England and Wales now actively encourage members of the public to submit dashcam footage of driving offences. A number of forces run dedicated online portals for this purpose, sometimes under names like "Operation Snap" or similar. The National Police Chiefs' Council has supported and promoted this approach.

The footage can be used to support charges for a wide range of offences, including dangerous driving, careless driving, using a mobile phone while driving, running red lights, and other road traffic offences.

What the police and CPS will consider:

1. Whether the footage is of sufficient quality to identify the vehicle, the driver, and the nature of the offence.
2. Whether the footage has been edited or tampered with, or whether it appears to be a complete and unaltered recording.
3. Whether the footage, taken together with any other evidence, meets the evidential test and the public interest test under the Code for Crown Prosecutors.
4. Whether a notice of intended prosecution was served within 14 days of the offence where required under section 1 of the Road Traffic Offenders Act 1988.

Practical points worth knowing:

The person who submitted the footage may need to provide a witness statement and could be called to give evidence at trial, though in many cases the footage itself does the heavy lifting.

If you are the person who has been reported, you are not obliged to say anything to the police, but you should be aware that a failure to identify the driver when required under section 172 of the Road Traffic Act 1988 is itself an offence.

If you receive a notice of intended prosecution or a single justice procedure notice, it is important to read it carefully and respond within the stated deadline. Ignoring it will not make it go away and may result in conviction in your absence.

Defence considerations:

If you are facing a prosecution based on dashcam footage, there are potential lines of challenge depending on the circumstances. These might include questioning the quality or completeness of the footage, whether the footage actually shows what the prosecution says it shows, whether you were in fact the driver, whether the footage has been taken out of context (for example, if it does not show what happened immediately before the incident), and whether the notice of intended prosecution was served in time.

It is also worth considering whether the footage actually discloses an offence at all. Sometimes what looks dramatic on camera does not meet the legal threshold for, say, careless or dangerous driving. Context matters.
