Quick Answer

A CARB hearing allows a vehicle owner or responsible party to present information regarding a Clean Truck Check enforcement action. Hearing requests generally must follow the instructions provided in the violation notice and should be submitted within any stated deadlines.

Receiving a Clean Truck Check violation notice does not necessarily mean the matter is beyond review. In some situations, vehicle owners or businesses may request a hearing with the California Air Resources Board (CARB) if they believe additional facts, documentation, or circumstances should be considered.

This article explains what a CARB hearing is, when hearing rights may be available, how to understand the instructions provided in your violation notice, and how to prepare supporting documentation if you decide to request a hearing.

A CARB hearing provides an opportunity for the recipient of a violation notice to present information regarding an enforcement action.

Depending on the circumstances, a hearing may allow you to explain why you believe the violation was issued in error, provide documentation supporting your position, or present other relevant facts for CARB’s consideration.

The specific hearing procedures are typically explained in the violation notice or other correspondence provided by CARB.

Section titled “When Should You Consider Requesting a Hearing?”

You may wish to request a hearing if:

  • You believe the violation was issued in error.
  • Your vehicle was already compliant before the notice was issued.
  • You have documentation showing the alleged violation is incorrect.
  • There are facts or circumstances that CARB may not have considered.

Every situation is different, so carefully review the information provided in your violation notice before deciding how to proceed.

Before requesting a hearing, gather any documentation that supports your position.

This may include:

  • Compliance test reports.
  • Demonstration of Correction forms.

  • Maintenance or repair records.Correspondence with CARB.
  • Any other records related to the alleged violation.

Having organized documentation can help CARB evaluate your request more efficiently.

  1. Carefully review the instructions contained in the violation notice.
  2. Follow all deadlines listed by CARB.
  3. Complete any required hearing request forms.
  4. Submit supporting documentation.
  5. Keep copies of everything you submit.

  • Read your violation notice carefully.
  • Submit your hearing request before the deadline.
  • Organize supporting documents clearly.
  • Maintain copies of all correspondence.
