If you missed your **CARB Clean Truck Check** deadline, you’re not alone—but ignoring it won’t make it go away. **Failure to complete required emissions testing on time can lead to fines, registration holds, and even being blocked from operating in California.** Here’s what happens and what you should do next.

### What Happens If You Miss the Deadline?

🚨 **Late Fees & Penalties** – CARB imposes fines for missed testing deadlines. The longer you wait, the more the penalties can add up.

🚨 **DMV Registration Holds** – If your truck isn’t compliant, **you may not be able to register your vehicle** when the time comes.

🚨 **Potential “Do Not Operate” Orders** – CARB has the authority to restrict non-compliant vehicles from operating in California.

### What Should You Do Now?

✅ **Get Tested Immediately** – Even if you’re late, getting tested as soon as possible can help minimize penalties and avoid further enforcement actions.

✅ **Check Your CARB Portal** – Log in to the **Clean Truck Check database** to see your compliance status, outstanding tests, and any potential fines.

✅ **Fix Any Issues** – If your vehicle fails, you’ll need to make repairs and retest quickly. **Testing early in the future (up to 90 days before the deadline) helps avoid these last-minute issues.**

✅ **Don’t Ignore It!** – If CARB flags your truck as non-compliant, enforcement actions will only get more severe over time.
