How often should I check CTC-VIS?

Fleet managers often review CTC-VIS weekly; owner-operators should check at least monthly and again 30 days before each due window. Status can change after tests post or fees lapse.

Should I keep copies of test results?

CTC-VIS is the system of record, but maintaining internal PDFs or screenshots helps during DMV renewals, audits, and driver disputes. Store results alongside registration and maintenance records.

Can I use this checklist for every vehicle?

Use it as a general workflow, then confirm vehicle-specific test type (OBD vs opacity), exemptions, and deadlines in CTC-VIS and on arb.ca.gov.

Clean Truck Check compliance checklist

Use this checklist to move a heavy-duty unit from “registered” to “compliant” without missing CARB deadlines. Adapt it for single-truck operators or scale it across a fleet spreadsheet.

1. Confirm eligibility & register

Verify the vehicle meets Clean Truck Check criteria using CARB guidance on arb.ca.gov and our who needs it guide. Create or access your CTC-VIS account, add the VIN, and confirm vehicle details match registration documents exactly.

Remove sold or totaled units promptly so your dashboard reflects active obligations only. Assign an internal owner for each VIN—especially in fleets where dispatch and maintenance sit in different departments.

2. Pay state fees & note due windows

Pay CARB’s compliance fee for each registered vehicle. A commonly cited annual amount is $32.13—verify the current fee in CTC-VIS before payment. Record the transaction in your fleet accounting system.

Capture the testing due window displayed in CTC-VIS and add calendar reminders at 60, 30, and 14 days before close. Cross-reference deadlines and testing frequency for phase-in changes.

Block dispatch on units that show non-compliant status—do not rely on drivers to self-report registration holds.

3. Pre-test & book credentialed testing

Identify test type: OBD for most 2007+ engines, opacity for many older diesels. Pre-screen dash lamps, smoke, and recent fault codes. Schedule early in the window via Zurfex.

Bring registration and ensure the cab is accessible. For mobile tests, confirm yard access, parking space, and a warm engine if opacity testing applies.

Fleets testing many units: use bulk scheduling to sequence appointments and reduce downtime.

4. After the test

Confirm pass/fail status in CTC-VIS within a few days. On pass, archive confirmation and resume normal dispatch. On fail, open a repair order immediately, fix root causes (not just codes), and rebook a credentialed retest within CARB timelines.

Understand penalties if retests slip. Review costs when budgeting repairs plus second inspections.

Duplicate this checklist each compliance cycle—quarterly testing will make it a core maintenance rhythm, not a yearly afterthought.
