Dash cams are legal in the UK
This is definitely the most important thing to know about dash cams in this context. You won’t require special permissions to use dash cam on UK roads since they are legal. In fact, you would just fit one in your car without the need to notify someone.
Certain situations of using dash cams require you to inform other people
You must inform others about a dash cam if your car is not solely for personal use. At times people share their vehicles, for example in instances of company schemes or a taxi service. You have to tell the other person in the car that they are being recorded. It is a matter of breach of privacy. If you sound record, sometimes even video record another person without them being aware, it is considered a serious breach of privacy. So if you operate a taxi, or you drive minicab, coach, cabbies and others, you must inform every passenger who enters your vehicle.
Dash cams can be used in court
Dash cams can provide valuable information in a case in court. There have been cases in the UK where dash cams have been used to prove a case that otherwise would have been left to testimony and conjecture. The first jail sentence to be handed with the aid of a dash cam in the UK was in 2015 when a dangerous driver was convicted with the assistance of an incriminating dash cam footage.
A dash cam by a concerned citizen helped the police, who then proceeded to arrest the driver. So yes dash cams are useful in law courts where necessary and have been used. In fact, there are so many cases of police tracking down lawbreakers in the country using dash cams. Driving solicitors also utilise dash cams to help prove cases
Incorrect installation of a dash cam is illegal
One thing that could invalidate your use of a dash cam is how it is fitted. It is very important to understand that dash cams should only be fitted in a way they don’t obstruct your field of driving while driving. You could be fined for unsafely positioning a dash cam. What is worse is that driving solicitors working for you may not use the footage recorded in an incorrectly installed dash cam since it is considered inadmissible in court. You could even be charged with a driving offence should a road traffic collision happen when you have an incorrectly mounted dash cam.
You can submit a dash cam footage to the police reporting law-breaking motorists on UK roads
Just any footage that shows another motorist breaking the law. In July 2018, Nextbase, a dash cam manufacturer partnered with the regional constabularies, (including the police forces) of England and Wales launched the National Dash Cam Safety Portal. This is where you can quickly and easily submit a footage to the authorities.
