How often should vehicles with heavy loads undergo inspection?

Vehicles carrying heavy loads are subject to more significant wear and tear compared to standard vehicles. Inspecting these vehicles more frequently than the annual requirement is essential to ensure they are safe to operate. Regular inspections help identify potential issues such as brake wear, tire condition, and structural integrity that can arise from the stress of heavy loads.

This heightened frequency of inspection is crucial for maintaining safety standards and preventing accidents caused by mechanical failures. It recognizes that heavy-load vehicles may encounter conditions that lead to accelerated degradation, warranting closer attention to their maintenance.

The other options suggest either infrequent inspections or specific circumstances that do not adequately address the comprehensive needs of vehicles operating under heavy loads. By focusing on more frequent inspections, it emphasizes the importance of proactive vehicle maintenance in promoting road safety.
