Which two types of inspections are mandated by DOT regulations?

The correct response highlights the importance of pre-trip and post-trip inspections as mandated by DOT regulations. These inspections are crucial for ensuring the safety and functionality of commercial vehicles.

Pre-trip inspections involve a thorough check of the vehicle's critical systems and components before it is operated, including brakes, lights, tires, and other essential functions. This practice is vital to catch any potential issues that could lead to accidents or breakdowns during transit.

Post-trip inspections serve to identify any damage or maintenance issues that may have occurred during the operation of the vehicle. This ensures that any problems are addressed promptly, contributing to overall vehicle reliability and safety.

Together, these inspections form part of a safety management strategy that helps protect drivers, passengers, and the general public by fostering a culture of responsibility and diligence in vehicle operation.
