The Vehicle Certification Agency has issued approval for Don-Bur’s Longer Semi Trailer Design, using a self-steer axle.
The 15.65m long trailer was built for Wincanton and the turning circle and safety tests were carried out by the VCA at the MIRA testing grounds to ensure Level 2 compliance under the LST technical requirements. The endorsement clears the way for a VSO (Vehicle Special Order) to operate trailers of the same design in the UK.
