What Is the Difference Between DOT Inspection and BIT Inspection?
Federal DOT inspections and California BIT inspections, often referred to as 90-day inspections, share similarities as safety checks, though there are some nuances.
The U.S. Department of Transportation’s Federal Motor Carrier Safety Administration (FMCSA) requires a DOT inspection for all commercial motor vehicles and trailers traveling outside of CA. The DOT inspections can be done at any time, but at least every 12 months. As a customer of Precision Diesel, our truck inspection team will ensure DOT inspections are performed correctly, following FMCSA standards and requirements, and as a productive part of your ongoing preventative maintenance program.
The California Commercial Motor Vehicle Safety Act of 1988, commonly referred to as the Biennial Inspection of Terminals (BIT) Program, was enacted by the California Legislature to alleviate the growing number of truck-related collisions on California’s highways. Terminal inspections have been conducted by the CHP since 1965 as a tool to determine if motor carriers are complying with Motor Carrier Safety regulations on an ongoing basis, particularly regarding the legal requirement to maintain commercial motor vehicles according to scheduled maintenance (preventive maintenance) program.
Periodic BIT inspections are state-regulated (by California) and mandatory for carriers every 90 days for commercial vehicles above 10,000 pounds GVWR. The actual inspection is the same as the DOT inspection. Certain vehicles will require more frequent checkups; passenger buses, for example, need to pass an inspection every 45 days. Inspections must be documented and inspection reports must be retained for at least two years.

The extensive Level 1 DOT inspection, the most common DOT inspection, covers a thorough examination of both the driver and the vehicle. This includes examining the vehicle, driver’s license, medical records, logs, HOS records, and inspection reports. It takes approximately 45 to 60 minutes. Level 2 DOT inspections focus on elements that can be verified without going beneath the vehicle, completing the inspection in around 30 minutes.
