What are the specific requirements for conducting MOT inspections on larger or heavier commercial vehicles, and how do these differ from those for private passenger vehicles?

The requirements for MOT (Minimum Operating Temperature) inspections on larger and heavier commercial vehicles differ significantly from those of private passenger cars due to their distinct characteristics and operational needs.

For commercial vehicles, such as buses, coaches, and heavy goods vehicles, the MOT focuses on assessing their roadworthiness in terms of safety, emissions, and environmental impact. These inspections are more rigorous and often involve specialized equipment to handle larger engines and complex systems. The test aims to ensure that these vehicles meet specific standards for performance, braking, steering, lighting, and exhaust emissions. This is crucial as commercial vehicles carry a higher potential risk due to their size and weight, impacting road safety and environmental considerations.

In contrast, private passenger vehicles undergo MOT tests to verify their compliance with basic legal standards for roadworthiness, including safety, emissions, and engine functionality. The process is less intensive compared to commercial vehicle inspections, and the focus is on ensuring that everyday cars are fit for safe driving without posing significant risks to themselves or others.
