What is the California Clean Truck Check?
Updated: Aug 6
The California Clean Truck Check (HD I/M Program) began in January 2023. Its goal is to reduce heavy-duty vehicle emissions throughout the state. For fleet operators in San Francisco, the East Bay, and San Jose, this means regular emissions testing, OBD (on-board diagnostics) checks, and proof of compliance with CARB regulations 2023.
Non-compliance can lead to fines, downtime, and loss of operating authority. However, with the right strategy, your fleet can stay ahead of the curve.

Why Compliance Matters for Bay Area Fleet
Fleet owners face more than just regulatory deadlines. Passing the California truck emissions test also impacts:
Operational Efficiency: Trucks that are out of compliance can be pulled from service.
Reputation: Customers increasingly demand sustainable, CARB-compliant operations.
Costs: Non-compliance penalties, repair costs, and downtime all eat into profits.
That’s why proactive planning is essential.
5 Proven Steps to Pass the California Clean Truck Check
1. Stay Informed on CARB Regulations 2023
The CARB Clean Truck Check requires routine OBD reporting and emissions compliance. Dogpatch Biofuels keeps Bay Area fleets updated on the latest California trucking law changes, so you’re never caught off guard.
2. Use Cleaner Fuels (Renewable Diesel)
Switching to renewable diesel delivery immediately reduces emissions. It helps trucks meet California heavy-duty vehicle emissions requirements. It’s a drop-in replacement for petroleum diesel, requiring no modifications.
3. Schedule Preventative Maintenance & Diagnostics
Regular OBD diagnostics and diesel truck maintenance help fleets identify issues before testing. Partnering with compliance-focused providers ensures your vehicles are always inspection-ready.
4. Ensure Proper DEF Supply & Quality
Modern diesel engines require DEF (Diesel Exhaust Fluid) for emissions control. Dogpatch Biofuels provides DEF delivery and bulk DEF solutions across San Francisco, East Bay, and San Jose. This ensures your fleet never runs out.
5. Work with a Local Compliance Partner
Passing isn’t just about testing—it’s about strategy. Dogpatch Biofuels offers fleet compliance consulting to align your fueling program, maintenance, and documentation with California Clean Truck Check compliance standards.
