Footage of Britain’s biggest and newest speed camera dubbed the ‘Long Ranger’ has been released by police.

The new camera has caught 1,200 motorists within the last month on the A417 in Gloucestershire where it is being trialled.

The clip released by the force shows a white Ford Transit van tailgating a car and in a longer clip a blue car is caught doing the same.

The camera can be moved around to catch offenders in the act on any road and comes as police have released figures showing that the new camera is making an impact.

In less than a month since it was deployed, well over 1,000 speeding offences have been recorded with the worst offender clocking a whopping 126 mph.

Tailgating, use of a mobile phone, vehicle plate offences and failure to use a seatbelt are among the other offences recorded.

But the machine also offers a hand to stricken motorists, with police using it to give assistance to 10 drivers who broke down and another 10 who needed help.

The A417 carries up to 35,000 vehicles a day, linking Gloucestershire with neighbouring Wiltshire, and is a pathway between the M4 and M5 motorways. It also has one of the worst accident records.
