More than 100 videos have been sent to Essex Police in the first month of a campaign to flag dangerous drivers.
Extra Eyes is designed to allow people an easy method to tell police about bad behaviour on the roads – in a bid to reduce crashes.
Of the clips submitted – 49 have led to officers taking action – including retraining courses or more serious prosecution.
In January 33 notices were sent out for careless driving – and another for dangerous driving.
Seven of the videos showed actual collisions around the county.
