When should drivers report any vehicle defects?

Drivers should report any vehicle defects immediately to ensure the safety and reliability of the vehicle on the road. Prompt reporting allows for timely maintenance or repairs, which is crucial for preventing accidents and mechanical failures. Addressing issues right away helps maintain compliance with safety regulations and successful operation within the National Safety Code guidelines. Immediate reporting not only protects the driver but also contributes to the overall safety of other road users.

In this context, the other options do not emphasize the urgency needed in addressing vehicle defects. While reporting within 24 hours, at the end of the day, or during a scheduled inspection may seem reasonable, they do not prioritize the immediate safety concerns that arise from a defect that could lead to serious consequences if not addressed right away.
