Heavy-duty trucks & fleets: get compliant this month with on-site CARB testing (OBD or smoke/opacity). No shop downtime.
Call 916-890-4427 NowOr book online — flexible windows available.
Why You Need This Now
Starting January 2025, CARB mandates **bi-annual emissions tests** on many heavy trucks (over 14,000 lbs GVWR). Enforcement will intensify through 2026. Operating without certification = registration holds, fines, and downtime.
- Failing to test can lead to **DMV registration holds**.
- Penalties are steep and accumulate per vehicle.
- Testing windows are limited—book early to avoid delays in Q4.
Which Test Does Your Truck Need?
It depends on your engine model year and emissions controls.
OBD / Computer Diagnostics
Required for newer vehicles with advanced engine control systems.
- Diesel engines 2013+ (often)
- Alternative fuel engines 2018+
- Gasoline >14,000 lbs
Smoke Opacity & Visual Inspection (J1667)
Needed for older diesels and engines without full OBD systems.
- Pre-2013 diesel
- Pre-2018 alt fuel engines
