Moment a lorry driver has to slam on the brakes after a car pulls in front with inches to spare.

This is the moment an HGV driver was forced to slam on the brakes after a car cut him up at high speed -- with inches to spare.

Dashcam footage shows the apparently impatient Peugeot 107 overtake lorry on the chevrons before slowing down to a complete stop ahead of the HGV on the A638.

The car comes so close to the huge vehicle it disappears below the dash camera mounted in the lorry - while the driver frantically hammers the horn.
