BIT Program Inspection & Maintenance Support in San Bernardino, CA

If you operate commercial trucks in California, staying current with required inspections and maintenance records is an important part of keeping your fleet compliant and ready for the road. Direct Truck & Auto Repair helps commercial vehicle owners and fleet operators in San Bernardino with periodic vehicle inspections, preventive maintenance, and repairs related to California's Basic Inspection of Terminals (BIT) requirements.

Call [Phone] or schedule an appointment online to have your commercial vehicle inspected or serviced.

What Is the Basic Inspection of Terminals (BIT) Program?

The Basic Inspection of Terminals, commonly called the BIT Program, is a California Highway Patrol program focused on commercial motor carrier safety. The program is designed to help determine whether carriers are properly maintaining regulated vehicles and keeping required maintenance and driver records.

Although the program was historically known as the Biennial Inspection of Terminals program, California changed the terminal inspection process to a performance-based selection system. This means CHP terminal inspections are not simply scheduled every two years for every carrier.

During a CHP terminal inspection, Motor Carrier Specialist personnel may review a sample of regulated vehicles, maintenance records, and driver records. Hazardous materials records and practices may also be reviewed when applicable.

Who May Be Subject to BIT Requirements?

BIT requirements apply to certain motor carriers and commercial vehicles operating in California. The rules can depend on vehicle weight, configuration, use, cargo, and the type of motor carrier operation.

Examples of vehicles that may fall under BIT requirements include certain:

• Commercial trucks with three or more axles
• Truck tractors
• Commercial truck and trailer combinations
• Heavy commercial vehicles based on weight ratings
• Vehicles transporting certain hazardous materials
• Other commercial vehicles regulated by applicable state or federal motor carrier requirements

Not every commercial vehicle is treated the same. Motor carriers should confirm the requirements that apply to their specific vehicles and operation.

How Often Do Regulated Vehicles Need to Be Inspected?

California requires carriers to make sure regulated vehicles receive periodic safety inspections at least every 90 days, or more often when needed for safe operation.

This periodic vehicle inspection is different from the CHP terminal inspection itself. The carrier is responsible for maintaining its vehicles and required inspection records between CHP terminal inspections.

Inspection and maintenance records generally need to be retained as required by applicable regulations. Keeping complete records can help demonstrate that the fleet has an active preventive maintenance program.

What Is Checked During a Periodic BIT Vehicle Inspection?

At a minimum, California's periodic vehicle inspection requirements include several important safety areas. These include:

• Brake adjustment
• Brake system components and possible leaks
• Steering and suspension systems
• Tires and wheels
• Vehicle connecting devices when applicable

The exact inspection and maintenance needs can vary depending on the truck, trailer, configuration, condition, and type of operation. If an inspection identifies a concern, additional testing or repairs may be needed before the vehicle can be considered properly maintained.

What Information Should Be Included in Periodic Inspection Records?

Proper documentation is an important part of BIT compliance. Periodic inspection records generally need to identify the vehicle and document the inspection and any required repairs.

At a minimum, the record should include information such as:

• Identification of the vehicle
• Vehicle make and model or another positive means of identification
• License number or company vehicle number when applicable
• Date and nature of the inspection
• Repairs performed as part of the inspection process
• The required signature from the motor carrier's authorized representative

Carriers are responsible for maintaining the records required for their operation. Requirements can change, so fleet operators should refer to current CHP and California regulations when managing compliance records.

What Happens During a CHP BIT Terminal Inspection?

A CHP BIT terminal inspection is broader than a single truck inspection. CHP Motor Carrier Specialist personnel may review selected vehicles along with maintenance and driver records to determine whether the motor carrier is following applicable safety requirements.

The review may include:

• Regulated commercial vehicles
• Vehicle inspection and maintenance records
• The carrier's maintenance program
• Required driver records
• Hazardous materials records and practices when applicable

CHP assigns safety compliance ratings in applicable categories. If a category receives an unsatisfactory rating, the carrier is informed of the condition and given direction on what must be corrected. CHP may then schedule a reinspection.

BIT Program FAQs

Does BIT still mean my terminal is inspected every two years?

Not necessarily. Although BIT was historically called the Biennial Inspection of Terminals program, CHP moved to a performance-based terminal inspection selection system. The timing of a CHP terminal inspection can depend on several factors.

Do my commercial vehicles still need 90-day inspections?

Regulated vehicles subject to California's periodic inspection requirements generally must be inspected at least every 90 days, or more often when necessary for safe operation. The requirements that apply can depend on the vehicle and motor carrier operation.

Is a 90-day vehicle inspection the same as a CHP BIT terminal inspection?

No. The periodic vehicle inspection is part of the motor carrier's ongoing inspection and maintenance responsibility. A CHP BIT terminal inspection is a broader compliance review performed by CHP personnel.

Does a BIT inspection only check the brakes?

No. Brakes are an important part of the periodic vehicle inspection, but other required areas include steering, suspension, tires, wheels, and vehicle connecting devices when applicable.

What happens if a truck does not pass an inspection?

The next step depends on what is found. A mechanical problem may require further testing or repair before the vehicle is returned to service. Direct Truck & Auto Repair can inspect the concern and explain the repair options based on the condition of the vehicle.

How long does a BIT-related inspection or repair take?

Timing varies depending on the vehicle, what needs to be inspected, what the inspection finds, and whether repairs or parts are required. After evaluating the vehicle, the shop can provide a better idea of the work involved.
