• Interpretation of Terms: Definitions of various technical terms and operational scenarios may be refined or expanded. Precise language is critical in inspection standards, so any changes here will aim to eliminate ambiguity for inspectors and operators alike.
• 07 Size & type of tyre: This is a critical area for HGV safety. Updates could involve more stringent requirements for load ratings, speed ratings, specific tyre constructions for certain applications, or even a greater emphasis on tyre condition beyond just tread depth, such as sidewall integrity and age. Incorrect tyre specification is a common cause of roadside prohibitions.
• 09 Sideguards, Rear under-run devices & Bumper bars: These components are vital for protecting vulnerable road users (pedestrians, cyclists, motorcyclists) from being drawn under the vehicle in a collision. Revisions here might focus on design standards, installation requirements, material integrity, or damage assessment criteria.
• 23 Glass & view of the road: Clear and unobstructed vision is fundamental for driver safety. Changes could relate to acceptable damage limits for windscreens and windows, tinting regulations, or the placement of aftermarket accessories that might impede the driver's view.
• 34 Pressure/Vacuum Warning and Build up: This section likely pertains to air braking systems, a complex and critical safety feature on HGVs. Updates might include more specific checks for warning system functionality, air pressure build-up times, or acceptable pressure loss rates, ensuring the braking system is always operating within safe parameters.
• 45 Fuel Tanks and Systems: Revisions could cover the security of fuel tanks, integrity of fuel lines, and prevention of leaks, all crucial for preventing fire hazards and environmental pollution. This might also extend to new requirements for alternative fuel systems if applicable.
• 59 Brake Systems and Components: Given the immense stopping power required for HGVs, any updates to brake system inspections are profoundly important. This could involve enhanced scrutiny of brake pads/linings, callipers, discs/drums, ABS/EBS components, and the overall condition of the hydraulic or pneumatic lines.
• 71 Service Brake Performance: This section focuses on the actual stopping capability of the vehicle. Updates might include revised performance thresholds, specific test procedures, or greater emphasis on brake balance across axles, ensuring the vehicle can stop effectively and predictably under various conditions.

Key Revisions for PSV MOT Inspection Manuals

For public service vehicles – buses, coaches, and minibuses – the updates also reflect the unique demands of passenger transport, where passenger safety is paramount. Operators in this sector must review these changes meticulously:

• About this manual: Similar to HGVs, an updated introduction might clarify procedural aspects or general guidance for PSV inspections.
• Interpretation of Terms: Refinements to definitions, possibly including terms specific to passenger carrying vehicles, will ensure consistency in inspection and understanding.
• 07 Size & type of tyre: As with HGVs, tyre regulations are fundamental. For PSVs, this might also consider the impact of passenger loads on tyre stress and the importance of correct specification for passenger comfort and safety.
• 16 Passenger Doors, Driver Doors and Emergency Exit: This is a highly specific and critical area for PSVs. Updates could focus on the operation, security, and integrity of all doors, including emergency exits. This might include requirements for automatic door mechanisms, anti-trap features, and clear signage for emergency procedures.
• 21 Interior of Body, Passenger Entrances, Exit Steps and Platforms: The internal environment of a PSV directly impacts passenger safety and experience. Revisions here might cover the condition of seating, handrails, flooring, step integrity, lighting, and the overall structural soundness of the passenger compartment.
• 23 Glass & view of the road: Driver visibility is key, but for PSVs, passenger window integrity and emergency hammer accessibility (where applicable) might also be under review.
• 45 Fuel Tanks and Systems: Similar to HGVs, the integrity of fuel systems is crucial for fire prevention and environmental protection. For PSVs, this might also consider the placement relative to passenger areas.
• 59 Brake Systems and Components: Brake performance is non-negotiable for PSVs, carrying multiple lives. Updates will likely mirror HGV changes, focusing on the rigorous inspection of all brake components to ensure optimal performance.
