Free Clean Truck Check deadline reminders

Enter your next test deadline and we email you 30 days and 7 days before it, then before every deadline after that. Free, no account, unsubscribe with one click. A missed deadline puts a hold on your DMV registration.

Shown in your CTC-VIS account. For California-registered trucks it is the DMV registration expiration date or six months after it.

OBD trucks move to four tests a year in October 2027, so their reminders come every three months from then on.

With a ZIP code, each reminder links to testers near you.

We send a confirmation email first. CTC Finder is an independent directory, not CARB; always check your exact dates in CTC-VIS. See our privacy policy.
