Check My Truck: What’s Due?
A missed MCS-150 can deactivate your USDOT number, and a missed Clean Truck Check can put a hold on your registration. Run a free truck compliance check: see your MCS-150 due date instantly, then we’ll confirm the rest and text you.
Step 1: Your MCS-150 due date
Your due date is built into your USDOT number. FMCSA uses the last digit for the month and the second-to-last digit for odd or even years.
Step 2: Everything else we check
- Clean Truck Check deadline. CARB sets it per truck in your CTC-VIS account. We’ll help you confirm it and test up to 90 days early.
- DMV registration and holds. We look at what’s blocking a renewal before it costs you a day.
- Form 2290 and Schedule 1. We make sure your proof of payment is ready for registration.
- MCS-150 filing. If you’re due or overdue, we can file it for you.
Send Us Your Truck
We’ll look up what’s due and text you, usually within 1 business day. No cost, no obligation.

Why a truck compliance check matters
The Deadlines a Free Truck Compliance Check Catches
Most trucks don’t get parked for big violations. Instead, they get parked for a date nobody was watching. That’s why we start every conversation with a quick check.
A deactivated USDOT number
FMCSA says a missed MCS-150 biennial update will deactivate your USDOT number and may bring civil penalties of up to $1,000 per day, up to $10,000.
“Nothing changed” still counts
FMCSA requires the biennial update every two years, even when none of your company information has changed.
A DMV registration hold
CARB says that once a Clean Truck Check registration hold is placed, DMV transactions for that truck are restricted until it is back in compliance.
Test deadlines are doubling
Most heavy-duty trucks test twice a year today. However, starting October 2027, CARB requires OBD-equipped trucks to test four times a year.
