What is DOT Inspection?

DOT inspections, also known as Department of Transportation inspections, are thorough inspections of commercial vehicles to ensure they meet safety and regulatory requirements. Inspections cover various components and documentation for both the vehicle and the driver.



How Often Do DOT Inspections Happen?

For all operating commercial motor vehicles, DOT inspections are required every 12 months.

Law enforcement may conduct random inspections at any time, especially at roadside checkpoints or inspection stations.


Who is subject to DOT Inspections


Every 25,000 miles or annually, the following vehicles must be inspected:


  1. Commercial motor vehicles that weigh over 10,000 pounds - DOT inspections are required for CMVs with a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) over 10,000 pounds. This includes a wide range of trucks and large vehicles used for commercial purposes.

  2. Vehicles Transporting More Than 16 Passengers (including the driver)

  3. Vehicles Transporting Hazardous Materials

  4. Passenger Buses

  5. School Buses

Driver

  • Driver Documents

  • Driver’s License

  • Medical Documents clearing you to driver

  • Hours of Service (HOS) logs

  • ELD

What are the six levels of truck inspections?


The six levels of truck inspections refer to the different levels of scrutiny and detail involved in roadside inspections conducted by enforcement officers, typically in collaboration with the Commercial Vehicle Safety Alliance (CVSA). These inspections are aimed at ensuring that commercial vehicles and drivers comply with safety regulations. Here's an overview of each level:


Level I: North American Standard Inspection (NAS)

  • Purpose: Comprehensive inspection covering both the vehicle and driver.

  • Vehicle Inspection: Brakes, fuel system, exhaust system, suspension, coupling devices, tires, wheels, lights, and more.

  • Driver Inspection: Driver's license, medical examiner's certificate, hours of service (HOS) compliance, record of duty status (RODS), and more.

  • Frequency: Most detailed and commonly conducted.

Level II: Walk-Around Driver/Vehicle Inspection

  • Purpose: Similar to Level I but without a detailed examination of the braking system.

  • Vehicle Inspection: Exterior components, such as lights, tires, brakes, coupling devices, and cargo securement.

Level III: Driver-Only Inspection

  • Purpose: Focuses on the driver's credentials and documentation.

  • Driver Inspection: Driver's license, HOS compliance, RODS, medical examiner's certificate, and other required documentation.

  • Vehicle Inspection: Limited to a cursory check to ensure the vehicle's roadworthiness.

Level IV: Special Inspection

  • Purpose: Inspection for a specific purpose, often involving a single component or system.

  • Example: Emissions inspection or an examination of a specific safety or compliance aspect.

Level V: Vehicle-Only Inspection

  • Purpose: Inspects specific vehicle components without assessing the driver.

  • Vehicle Inspection: Brakes, lights, tires, coupling devices, and other mechanical components.

  • Driver Inspection: Not included in Level V.

Level VI: Radioactive Materials Inspection

  • Purpose: Specific to vehicles transporting radioactive materials.

  • Inspection Focus: Ensures compliance with regulations governing the transportation of radioactive cargo.

  • Frequency: Rare, given the specialized nature of the cargo.


What are the most common violations?

Common violations against drivers include:

  • Logging violations

  • No medical card, or it’s expired

  • Invalid or expired license

  • Not wearing a seat belt

  • Exceeding HOS laws

Common violations against CMVs include:

  • Inoperable lights
