If a driver suspects there is a major defect in a vehicle, what should they do?

When a driver suspects a major defect in a vehicle, the most responsible action is to inform the carrier immediately. This is crucial because the safety of the driver, other road users, and the integrity of the vehicle is at risk. Reporting the suspected defect allows the carrier to assess the situation promptly and take necessary actions, which could include arranging for repairs or bringing in a replacement vehicle.

Continuing to drive to a service station could exacerbate the problem, potentially leading to an accident or further damage. Waiting for the next scheduled inspection does not address the immediate concern and could leave the vehicle unsafe for operation in the meantime. Disabling the vehicle and calling for assistance is an appropriate action in certain scenarios, but notifying the carrier fosters coordination in ensuring vehicle safety and compliance with regulations. Thus, direct communication with the carrier is paramount when a major defect is suspected.
