How often should a driver conduct a pre-trip inspection?

A driver should conduct a pre-trip inspection before every trip to ensure that the vehicle is safe for operation and meets all regulatory requirements. This routine check is crucial for identifying any potential issues that could compromise safety on the road, such as mechanical failures, tire conditions, or fluid levels. By performing this inspection regularly, drivers can prevent accidents, ensure compliance with regulations, and maintain the overall performance of the vehicle.

Neglecting this practice, as suggested by the other options, could lead to undetected mechanical issues arising later, which might cause dangerous situations during the trip. Monthly inspections, inspections only when trouble is apparent, or seasonal check-ups do not provide the same level of assurance that a thorough examination before each journey does. Consistent pre-trip inspections are key to responsible vehicle operation and safety.
