One platform. Every truck. Fully compliant.

Mobile Tester Booking

Find and book a CARB credentialed mobile HD I/M tester in your area. On-demand or pre-scheduled — testers come to your yard, job site, or depot.

Fleet Compliance Dashboard

Track every vehicle in your fleet. See upcoming test deadlines, CARB fee status, tester notes, and compliance certificates — all in one dashboard.

Trucker Roadside Network

Real-time alerts from fellow truckers within a 30-mile radius. Road hazards, weigh station status, CHP checkpoints, traffic conditions — reported by drivers, for drivers.

Repair Shop Profiles

Browse repair shop profiles, compare turnaround times, and reschedule service visits directly. When a truck fails its test, the path to getting back on the road is clear.

Vehicle Status Alerts

Get notified when a vehicle is down, when fees are due, when testing window opens, and when tester notes are added — so nothing falls through the cracks.

CARB CTC-VIS Ready

All tester submissions flow directly to CARB's Clean Truck Check Vehicle Inspection System. Compliance certificates issued and tracked automatically.

From registration to compliance — in three steps.

01

Add your vehicles

Register your trucks, buses, and motorhomes. Tag them by fleet, set testing schedules, and link to your CARB CTC-VIS account.

02

Book or schedule a test

Choose a mobile CARB credentialed tester, pick a date and location, and confirm. Testers come to you — no driving to a station required.

03

Results go straight to CARB

Test data submits directly to CTC-VIS. Compliance certificate issued. Fleet dashboard updates in real-time. Alerts fire 90 days before the next deadline.

CARB Clean Truck Check is not optional.

Non-compliance means DMV registration holds, civil penalties, and potential removal from service. Every non-gasoline vehicle over 14,000 lbs GVWR operating in California must be registered, tested, and fee-current — including out-of-state trucks. TruckCheck Pro keeps you ahead of every requirement.

Built for California truckers

The truck stops when compliance lapses. Don't let it.

TruckCheck Pro is built to handle the full lifecycle of CARB Clean Truck Check compliance — from first registration to quarterly test submissions, from tester booking to repair shop rescheduling. One platform that keeps your fleet on the road and your compliance current.
