Boss Cabins van follows another Boss Cabins van onto roundabout and cuts up the HGV dash cam vehicle, almost causing a collision.
"M25 Jct 21a Anti Clockwise, 7/2/2018.
After leaving the M25 to head towards Hatfield I travel up to the roundabout where I need to turn right. Travelling towards my exit on the roundabout I notice two vans with the same livery belonging to Boss Cabins waiting to enter the roundabout.
The first of the vans leaves it late to pull out and turn left but what his mate in the second van does is unthinkable. Instead of waiting, he decides he needs to be behind his colleague and pulls out in-front of my truck only just avoiding a collision."
Slamming your brakes on in a 40mph limit (which you were driving at) when you come to a speed camera isn't very clever.
