This footage shows the moment a cyclist confronted a driver who he claims was watching a film on her mobile while behind the wheel.

The female motorist, who was stuck in stationary traffic at the time, initially denied she had been watching TV but said she had been playing a film and just listening to the soundtrack.

Police later traced the driver but said there was not enough evidence to go ahead with a prosecution.

The cyclist can be heard in the video, filmed on the Wilderspool Causeway in Warrington, Cheshire, saying: “The police can arrest you for that, take your licence.

“Roads aren’t dangerous enough? I’ve lost friends to people like you.”

The cyclist said he had seen the woman watching her phone screen in stationary traffic before knocking on the window to confront her.

She initially denies watching TV before appearing to admit: “It’s, er, it’s a film.”

The Ford driver later insists she is not watching the screen and is only listening to the audio.

The motorist later told police she was not watching a film and was, in fact, using her phone as a satnav.

The anonymous bike rider, a member the Stop Killing Cyclists campaign, the CTC national cycling charity and Greater Manchester Cycle Campaign, told the Liverpool Echo : “There is no excuse for watching a film in your car while driving and the law reflects this.

"Sadly, the enforcement of those laws is where the danger is allowed to persist.”

Sgt Neil Farnworth, from Cheshire Police, said: “An officer has viewed the video footage provided by the cyclist. It is not clear from the footage what, if anything, was being viewed by the driver at the time or whether any offences were being committed.

“The driver was traced and spoken to and said that she was viewing a satnav system on her phone. On this occasion, there is not sufficient evidence to proceed with any sort of prosecution.”
