The Driver and Vehicle Standards Agency (DVSA) have announced changes to the MOT inspection standards for Heavy Goods Vehicles (HGVs). Changes will come into effect from 1st April 2025.
To help you keep on top of these updates SmartCheck have summarised key changes below:
Side Guards and Rear Under-Run Devices
The section on side guards and rear under-run devices has been adjusted to improve clarity and flow. A notable update includes a new list of vehicle exemptions from side guard requirements. New images have also been included to demonstrate side guard areas for different vehicle types. The new exemption list includes articulated tractor units, category T vehicles, gulley/cesspool emptiers, and car transporters where chassis rails are on the vehicle's extremities.
Glass and Indirect Vision Devices
Updates have been made to the standards concerning glass and the driver's view of the road, specifically addressing monitors used for indirect vision devices. These changes aim to recognise advancements in vehicle technology such as growing use of camera systems and ensure clear visibility standards are maintained.
Pressure/Vacuum Warning and Build-Up
Sections regarding pressure and vacuum warning systems have been clarified, particularly for towing vehicles. The manual now specifies that these vehicles must meet build-up time requirements regardless of whether a trailer is attached. Type-approved towing vehicles are allowed a build-up time of up to six minutes, compared to the standard three minutes for pressure systems and one minute for vacuum systems.
Fuel Tanks and Systems
The inspection scope for fuel tanks and systems has been expanded to include hydrogen fuel cell tanks. A new paragraph has been added covering LPG, CNG, LNG, and hydrogen tanks, which are now subject to testing. It's also noted that fuel tanks and gas cylinders will only be subject to visual inspection for corrosion.
Brake Systems and Components
Clarifications have also been added concerning brake systems, particularly regarding pipe wall thickness standards. The manual now states that a pipe with its wall thickness reduced by more than one-third of its original thickness is considered a major or dangerous deficiency, depending on severity. This aims to provide clearer guidance for inspectors and ensure consistent application of standards.
These updates reflect the DVSA's commitment to enhancing vehicle safety and ensuring that inspection standards keep pace with technological advancements and evolving industry practices.
