A California BIT inspection checks the carrier’s overall terminal safety program, not only the trucks parked on the lot. California Highway Patrol Motor Carrier Specialists may sample regulated vehicles, maintenance files, driver records, hours-of-service records, and hazardous materials practices when they apply. Controlled substances and alcohol testing is evaluated separately under its own CHP checklist.
Use this California BIT inspection checklist as a working review before CHP arrives. Every vehicle in the sample should match its records, and every requested file should be current and easy to produce. Carriers that want a hands-on review can use our California BIT inspections and audits team to test the same records before the visit.
Start With the Terminal and Fleet Roster
A useful checklist starts with the vehicles and terminals CHP can select. Confirm that the legal name, CA number, USDOT number, terminal locations, and current fleet roster agree across your records. A unit that was added, transferred, sold, or placed out of service should not be sitting in a paperwork gray area.
Review the following before you pull maintenance files:
- Every California terminal from which regulated vehicles are operated or dispatched is identified with CHP.
- Each active unit appears on the maintenance schedule under a positive identifier such as unit number, license number, make, and model.
- Leased vehicles show the lessor or contractor information required in the maintenance record.
- Company names and identification numbers match the authority under which each vehicle operates.
- Sold, transferred, and retired units are removed from active schedules and closed out in the record system.
This first pass prevents a common problem: the fleet list says one thing while the maintenance calendar says another. CHP samples from the operation it finds, not from the shorter list a carrier hoped to present.
Check 90-Day Inspections and Maintenance Records
CHP reviews whether each regulated vehicle has a current periodic inspection and a systematic maintenance history. California Vehicle Code Section 34505.5 requires covered vehicles to be inspected at least every 90 days, with shorter intervals when safe operation calls for them. The inspection report must connect the unit, the work performed, and any completed repairs.
For each vehicle in your sample, confirm:
- The latest 90-day inspection falls within the required interval.
- The report identifies the vehicle by make, model, license number, company unit number, or another positive identifier.
- The date and nature of the inspection are recorded.
- Repairs are documented and tied back to the defect or inspection entry.
- The motor carrier’s authorized representative has attested to the inspection and required repairs, or the electronic record contains the information accepted under the statute.
- Inspection reports are retained for two years and can be produced without searching through several systems.
Also review the maintenance program around the 90-day report. CHP 800D asks whether each vehicle is regularly inspected, maintained, and lubricated, and whether the carrier has a method for showing which services are due by date or mileage.
Driver vehicle inspection reports belong in this review too. CHP 800D calls for documented DVIRs, correction of safety defects before highway operation, and retention of those reports for at least three months.
For the full periodic inspection rule, see our 90-day BIT inspection requirements guide.
Compare the Records With the Vehicle
A clean file does not carry much weight when the selected vehicle shows long-standing defects. CHP compares the maintenance history with the physical condition of the sample, so the paperwork and the truck need to tell the same story.
The basic vehicle inspection items under California’s BIT program are:
- Brake adjustment
- Brake system components and leaks
- Steering and suspension systems
- Tires and wheels
- Vehicle connecting devices
The CHP 108 form covers additional items such as warning devices, air systems, frames, wheel seals, lights, wiring, fuel systems, exhaust components, and mirrors. The starred items on the form identify the minimum requirements under Section 34505.5, but a sound maintenance program should address every safety defect found during inspection or operation.
A recent CVSA Level I roadside inspection report may be used by CHP as part of its terminal vehicle sample when it was completed within 90 calendar days of the terminal inspection. It does not replace the carrier’s own 90-day periodic inspection.
Review Driver and Employer Pull Notice Records
Driver records are a separate rating area during the terminal inspection. A fleet can be mechanically sound and still receive an unsatisfactory result when driver files show missing records, unqualified drivers, or a pattern of hours-of-service violations.
Build a sample from the drivers who are actually working now. Check:
- A California DMV driving record issued within 30 days before hire, when required.
- A signed and dated review of the driver’s record before unsupervised operation.
- Enrollment in the DMV Employer Pull Notice program for every driver who must be enrolled.
- A current EPN record and documented review of license status, restrictions, and disqualifying actions.
- The employment application and qualification documents required for the driver’s position.
- Current license, endorsement, and medical qualification documents when they apply.
- A record showing the vehicle types and combinations the driver has demonstrated an ability to operate proficiently.
Driver files need to be complete, current, and organized before inspectors arrive. A missing medical certificate or unsigned log entry is a deficiency. Deficiencies affect your California Performance Safety Score (CPSS), which determines how frequently your terminals are selected for future inspections.
Match Hours-of-Service Records to the Operation
Hours-of-service rules depend on the type of operation, so one limit should not be applied to every driver. California intrastate property-carrying operations can be subject to the 80-hours-in-eight-days limit, while interstate operations generally follow the federal limits that apply to them.
CHP 800D asks carriers to retain logs, timekeeping records, and supporting documents for at least six months. The review should verify:
- Each driver is using the correct log, electronic logging device record, or local timekeeping method.
- On-duty, driving, off-duty, and release times agree with dispatch and payroll records.
- Fuel receipts, bills of lading, toll records, and other supporting documents do not conflict with the driver’s record.
- New or intermittent drivers provide the required statement of prior on-duty time.
- Daily and cycle limits are tested under the rules that apply to that driver’s work.
A problem usually appears in the cross-check. A log may look complete on its own, then a fuel receipt or dispatch timestamp places the driver somewhere else.
If the cross-check exposes a pattern, address hours-of-service compliance before the terminal review.
Review CSAT Compliance as a Separate File Set
CHP evaluates controlled substances and alcohol testing separately from the general terminal checklist. Carriers with drivers subject to 49 CFR Part 382 should use CHP 800F to review the testing program and record retention rules.
At a minimum, confirm:
- Required pre-employment drug testing was completed before safety-sensitive work.
- Every covered driver is included in a compliant random testing program.
- FMCSA Drug and Alcohol Clearinghouse pre-employment queries were completed.
- Annual Clearinghouse queries are current for every covered CDL driver.
- Policies, test records, refusals, return-to-duty documents, and follow-up testing records are retained for the applicable period.
- Records held by a consortium or third-party administrator can be produced within 48 hours of a CHP request.
Add Hazardous Materials Records When They Apply
CHP adds hazardous materials records and practices when the carrier transports hazardous materials or hazardous waste. Shipping papers, placards, employee training, emergency response information, security plans, package condition, and incident records can become part of the inspection.
Keep this material in its own audit section. Mixing hazardous materials records into general driver files makes it harder to see missing dates, expired training, or a document that cannot be produced from the vehicle.
Know How CHP Rates the Terminal
CHP assigns satisfactory or unsatisfactory ratings to regulated vehicles, the maintenance program, driver records, and hazardous materials when applicable. Motor Carrier Specialists do not issue citations for violations discovered during the terminal inspection. They document the condition and assign the rating.
When every category is satisfactory, the next review returns to the performance-based selection system. If a category is unsatisfactory, CHP provides correction direction and schedules a reinspection within 120 days. A conditional rating is available only in limited reinspection circumstances.
The official CHP 800D checklist lists examples that can support an unsatisfactory rating, including long-standing equipment violations, widespread maintenance failures, excessive hours-of-service violations, missing EPN participation, and failure to give CHP a reasonable opportunity to inspect.
Run a Final File-Pull Before Inspection Day
The last step is a timed file-pull using a realistic sample. Pick several active vehicles and drivers, then have the employee who will assist CHP produce the related records without coaching.
The final review should answer these questions:
- Can the team produce the current vehicle list and terminal information immediately?
- Can each selected 90-day report be matched to repair records and the maintenance schedule?
- Can driver, EPN, and hours-of-service records be produced for the same period?
- Can CSAT and hazardous materials files be produced by the people responsible for them?
- Do employees know who will communicate with the Motor Carrier Specialist and where the inspection will take place?
This exercise finds practical problems that a document-only review misses, such as a supervisor who is absent, a password no one else has, or records stored under an old unit number.
Prepare With Former CHP Motor Carrier Specialists
Our team prepares carriers from the perspective of the people who conducted these reviews. Our principals served as CHP Motor Carrier Specialists, and our senior partner managed the Northern Division Motor Carrier Safety Unit for 36 years. Together, our founders bring more than 65 years of enforcement experience.
We can review the same mix of vehicles and records CHP is likely to sample, explain the findings, and work with your staff on corrections before the inspection. We also provide California BIT inspector certification training for mechanics and maintenance teams responsible for periodic vehicle inspections.
