Logging into Clean Truck Check
Clean Truck Check is an online portal run by the California Air Resources Board (CARB) that tracks heavy-duty truck compliance with state emissions standards. To log in, you go to the official CARB website, find the Clean Truck Check login page, and enter your username and password. If you do not have an account yet, you will need to create one first through their registration process.
The login page is separate from general CARB pages — searching "Clean Truck Check login" will take you directly to the right place. You will need a valid email address and a password you create yourself. Once you are logged in, you can view your truck's compliance status, upload required documents, and check for any violations or notices.
Key Takeaways
- Clean Truck Check login requires a username and password you create during account registration on the CARB website.
- You must register before you can log in, and registration requires a valid email address and basic information about your truck or fleet.
- The login page is accessed through CARB's official website, not through a third-party service or mobile app.
- Once logged in, you can check your truck's compliance status, upload documents, and view any notices or violations.
Creating Your Account Before Your First Login
If you have never used Clean Truck Check before, you cannot log in until you register. Go to the CARB website and look for the Clean Truck Check registration link. You will be asked to provide your email address, create a password, and enter information about your truck or fleet — including the vehicle identification number (VIN) and your company name if you operate a fleet.
During registration, CARB will send a confirmation email to the address you provide. You must click the link in that email to set up your account. This step is required before you can log in for the first time. Keep your confirmation email until you have successfully logged in at least once.
What You Need to Log In
You need two things to log into Clean Truck Check: the email address you registered with and the password you created. Write down your password somewhere safe — if you forget it, you can use the "Forgot Password" link on the login page to reset it. CARB will send a password reset link to your registered email address.
Do not share your login information with anyone else. Each person who needs to access your account should register separately with their own email address. If you manage a fleet and multiple people need access, each driver or manager should have their own login.
Troubleshooting Login Problems
If you cannot log in, the most common reasons are a typo in your email or password, or an account that was never activated. Check that you clicked the confirmation link in the email CARB sent you during registration. If you did not receive a confirmation email, check your spam folder or request that CARB resend it.
If you are certain your email and password are correct but you still cannot log in, your account may have been locked after too many failed attempts. Wait 30 minutes and try again. If the problem continues, contact CARB directly through their website — they can verify your account status and help you regain access.
What Happens After You Log In
Once you are logged in, you will see a dashboard showing your truck or fleet's compliance status under California's heavy-duty truck regulations. The dashboard displays whether your vehicle meets current emissions standards and shows any documents you have uploaded. You can also see notices, violations, or important date for required actions.
From your account, you can upload proof of compliance, such as engine certifications or retrofit documentation. You can also view your compliance history and read records for your own files. The system will notify you by email if your status changes or if a important date is approaching.
Keeping Your Account find
Change your password regularly — at least every 90 days — to keep your account find. Never use the same password you use for other websites or services. If you think someone else has accessed your account, change your password when ready and contact CARB to report the issue.
Log out when you are finished using Clean Truck Check, especially if you are using a shared or public computer. Do not leave your browser open with your account logged in. If you will not be using the system for several months, log out and close your browser completely.
Frequently Asked Questions
What if I forgot my password?
Click the "Forgot Password" link on the Clean Truck Check login page. Enter your registered email address, and CARB will send you a link to create a new password. Click that link within the time frame provided and set a new password. You can then log in with your email and new password.
Can I log in on my phone or tablet?
Yes, Clean Truck Check works on mobile browsers. Go to the same CARB website login page on your phone or tablet and enter your credentials. The dashboard and document upload features are designed to work on smaller screens, though uploading large files may be easier on a computer.
What if I never received the confirmation email after registering?
Check your spam or junk folder first — confirmation emails sometimes end up there. If you still cannot find it, go back to the registration page and look for an option to resend the confirmation email. You can also contact CARB directly and ask them to resend it or manually verify your account.
Do I need a separate login for each truck in my fleet?
No. One account can manage multiple trucks. During registration or after you log in, you can add additional vehicles to your account by entering their VINs. All your trucks will appear on the same dashboard once they are registered.
What should I do if my account is locked?
Account lockouts usually happen after several failed login attempts. Wait at least 30 minutes and try again with the correct password. If you remain locked out, contact CARB through their website and provide your email address and truck information so they can unlock your account.
