One in four dash cam submissions have ended in prosecution, with all police forces now accepting dashcam footage.
In data analysed by the RAC, around 89 dashcam submissions were made a day for an alleged driving offence to police forces, with 32,370 in total sent in 2019.
This is double the number submitted in 2018, with only 15,159 sent to 24 police forces.
RAC submitted a Freedom of Information Act request to every police force in the country and found that of the footage submitted, 8148 (25%) resulted in prosecutions by the police.
Dashcam footage can be submitted to Thames Valley Police via Nextbase safety portal, which the police say saves them eight hours per case.
Nextbase said that more than half the footage submitted to their safety portal has resulted in convictions, claiming they've saved police forces at least 170,000 hours on those convictions.
The footage sent to police ranged from dangerous driving to contravening red light and no entry sign, to using a mobile phone while driving and even driving without a valid MOT.
RAC road safety spokesman Simon Williams said: “Even before the decline in the number of roads police enforcing traffic offences, law-abiding drivers were often frustrated that there was never an officer there to deal with infringements they witnessed.
“As so many drivers and cyclists are now using dash cams and helmet cameras every road user needs to be very conscious that any of their actions that aren’t in accordance with the law could end up with the police.
"Some will inevitably find this out the hard way while others will hopefully become increasingly mindful of it.”
Those who want to submit dashcam footage directly to Thames Valley Police can do so via their online reporting system.
