DOT inspections are conducted by the FMCSA and are part of the U.S. Department of Transportation (DOT).

The DOT inspection process maintains high levels of safety and compliance in the commercial transportation industry by employing a range of qualified professionals and ensuring rigorous training and certification standards.

DOT inspections are conducted by qualified inspectors who have received proper training and certification. These inspectors must meet specific criteria established by the Federal Motor Carrier Safety Administration (FMCSA).

Many states have their own enforcement agencies that conduct DOT inspections as part of their commercial vehicle enforcement programs. These state inspectors are trained and certified to perform inspections according to federal standards.

Commercial vehicle enforcement officers, including state troopers and highway patrol officers, conduct roadside DOT inspections. These inspections can be random or targeted based on observed violations or safety concerns.

Some DOT inspections can be conducted by third-party service centers that are authorized and certified by the FMCSA. These centers may be part of larger truck service chains or independent operators who meet the certification requirements.

Larger transportation companies may employ their own certified inspectors to conduct internal DOT inspections. These inspections help ensure ongoing compliance and readiness for official DOT inspections.

Driver Inspection

  • Driver Qualifications: Verifying the driver’s commercial driver’s license (CDL), endorsements, and medical examiner’s certificate.
  • Hours of Service: Review driver logbooks or electronic logging devices (ELDs) to ensure compliance with hours-of-service regulations, which limit the amount of time a driver can be on duty and require rest periods.

  • Driver’s Record of Duty Status: Inspecting the driver’s daily logs and supporting documents to verify that they accurately reflect the driver’s duty status and hours worked.

Operational Compliance

  • Cargo Securement: Ensuring that all cargo is properly secured and the vehicle is not overloaded. This includes checking tie-downs, straps, and other securement devices.
  • Hazardous Materials: For vehicles transporting hazardous materials, verify that the materials are properly labeled, packaged, and documented according to regulations. Inspect for proper placarding and ensure that the driver has the appropriate endorsements and training.
  • Documentation: Review various required documents, such as vehicle inspection reports, maintenance records, and shipping papers for hazardous materials.

Types of DOT Inspections

  3. Level III – Driver-Only Inspection: Focuses solely on the driver’s documentation and compliance.
  4. Level IV – Special Inspections: Conducted to gather data on a specific aspect of a vehicle or driver, often as part of a research effort.
  5. Level V – Vehicle-Only Inspection: Conducted without a driver present, often during an annual inspection.

Level VI – Enhanced NAS Inspection for Radioactive Shipments: Specific to the transportation of radioactive materials, ensuring compliance with additional safety protocols.
