The devices, known as “dash-cams” record the view through the windscreen and capture events before, during and after a collision.

The products are being offered as a new scam, dubbed “flash for cash”, comes to light where fraudsters flash their headlights to give victims the impression they are being allowed to join a main road but then accelerate in order to hit the unsuspecting driver side-on

The recorded footage can also be used by defendants against accusations of lane-hogging or tailgating on motorways following new fixed penalty legislation which came into force in August.‎

Halfords in-car technology manager Alec James said: ‘Following an incident people are often reluctant to admit guilt and risk losing their no claims discount. In addition, the surge in fraudulent so-called “crash for cash” claims is causing genuine concern among innocent drivers.

‘The range of recording devices we now offer means that we can provide drivers with the means to produce evidence of how an incident occurred and who is at fault should the need arise.’
