What Each Inspection Covers & Why It Matters
Missing an inspection or failing an audit can mean fines, out-of-service orders, and lost revenue. Here's what you need to know about each one.
Federal FMCSA requirement for every commercial vehicle. Covers brakes (including air system), lights and reflectors, tires and wheels, steering, suspension, frame and body, coupling devices, exhaust system, and windshield wipers. Must be performed annually by a qualified inspector, and the report must be kept on file for 14 months.
California CHP program for fleets with commercial vehicles. Requires an approved maintenance program, regular vehicle inspections (every 90 days for most fleets), and proper documentation of all maintenance and repairs. CHP audits your records — we make sure they're complete and organized.
Required for BIT-enrolled fleets every 90 days (45 days for some vehicle types). Covers the same critical safety systems as a DOT inspection but on a more frequent schedule. Missing a 90-day puts your entire BIT program at risk and can result in terminal-wide out-of-service orders during CHP audit.
California's emissions compliance test for medium and heavy-duty diesel trucks. Tests OBD system for active emissions-related fault codes and verifies aftertreatment system functionality. Starting 2024, required for registration renewal and terminal entry at ports. We test with CARB-approved equipment — if you fail, we diagnose, repair, and retest on-site.
Common Questions
How much does a DOT inspection cost in San Diego?+
Call us at (619) 848-0459 for current DOT inspection pricing. If repairs are needed to pass, we provide a separate estimate before doing any work.
What happens if my truck fails a DOT inspection?+
We'll identify exactly what failed and provide a repair estimate. Most common failures are brakes, lights, and tire issues — all of which we can fix on-site. Once repaired, we re-inspect and certify the vehicle.
How often do I need a BIT inspection?+
Most BIT-enrolled vehicles require inspection every 90 days. Some vehicle types (like school buses and tour buses) require 45-day intervals. We track your schedule and send reminders so you never miss a cycle.
Do you provide documentation for CHP audits?+
Yes. Every inspection comes with proper documentation formatted for CHP compliance. We maintain records of all inspections, deficiencies found, repairs performed, and re-inspection results — ready for audit review.
What is the CARB Clean Truck Check?+
It's California's emissions compliance test for diesel trucks. The test reads your truck's OBD system for active emissions-related fault codes. Starting in 2024, trucks need to pass to renew registration and access port terminals. If you fail, we diagnose the issue, perform the repair, and retest — all at our shop.
Can you handle inspections for my entire fleet?+
Yes. Fleet inspection programs are one of our specialties. We schedule, track, perform, and document inspections for your entire fleet — DOT, BIT, 90-day, and CARB. Learn about fleet programs →
