Speeding is different
Can dash cam footage be used for speeding?
Probably not, and here is why. Named serving and former police officers describe the public footage submission scheme as built for careless and dangerous driving, mobile phone use and close passes, not for catching speed.
This is not legal advice. This page reports what the sources below say. We are not solicitors, and we do not fit or test dash cams. If you need advice on your own situation, speak to a solicitor.
What serving officers actually say
Quotes named serving and former police officers stating the footage submission scheme is not designed to detect speeding offences.
This is a named source, not an anonymous forum claim: a serving superintendent and a former motorcycle police sergeant, quoted in the same article, describe the scheme in terms of the offences it is built to catch. Speed is not one of them. That is a meaningful gap between what the scheme is for and what people assume it is for.
The contrast with footage used against you generally
Camera footage that shows that the driver doing the filming is using a mobile phone, driving aggressively or committing other traffic offences may result in them being prosecuted as well.
The strongest source for "your own footage can be used against you". An official police service, not a law firm.
This is a different question from speeding specifically. Ask the Police confirms that your own footage can be used against you if it shows you using a mobile phone, driving aggressively, or committing other traffic offences. That is a general statement about footage as evidence. It is not a statement that the submission scheme is built to catch speed, and the two should not be conflated.
What we could not find. We looked for a sourced, named example of someone prosecuted for speeding from dash cam footage they submitted themselves. We found none. We are stating that gap rather than filling it with an invented case.
Questions
Can dash cam footage be used to prosecute for speeding?
Probably not. Named serving and former police officers describe the public footage submission scheme as built for careless and dangerous driving, mobile phone use and close passes, not for detecting speeding.
Has anyone been prosecuted for speeding because of dash cam footage they submitted?
We found no sourced example of this happening. That is a gap in what is publicly documented, not proof that it has never occurred.
What is dash cam footage submission actually used for?
Officers quoted on the topic describe careless and dangerous driving, mobile phone use, and close passes as the kinds of offences the scheme is designed to catch, rather than speed.
If footage doesn't catch speeding, can it still be used against the person who filmed it?
Yes, for other offences. An official police information service states that footage showing the person filming using a mobile phone, driving aggressively, or committing other traffic offences may result in them being prosecuted too. That is a separate question from whether the scheme detects speeding.
