Latest updates to DVSA inspection manuals for HGV and PSV

From 1 April 2023, some changes will take effect in the HGV and PSV inspection manuals.

Following earlier guidance, free-rolling tyres fitted on front steered axles will be a failure.

Also added, in response to modern technology introduced on heavy vehicles, is a deficiency (failure) for loose wheels studs/bolts to the hub, including wheel flanges.

The standards to apply for cuts and damage to seat belt webbing has been clarified.

A deficiency (failure) has been added for any flashing stop lamp. A prohibition will be issued if all are flashing.
