Compliance Assistance Program (CAP)

About the Program

Introduction/Mission Statement

The goal of the Compliance Assistance Program is to help ensure that participants in the motor vehicle and equipment industry – especially new entrants and small manufacturers – have access to information and tools to fully understand and comply with their federal obligations. NHTSA’s Compliance Assistance Program will be transparent in providing the resources and education needed for entities to be successful, and will provide a direct channel for communication between commercial entities and NHTSA.


Program Contact Information

NHTSA’s Compliance Assistance Program site will continue to evolve over time. Current and prospective manufacturers may contact NHTSA for guidance on compliance issues at: NHTSA aims to provide quick, straight-forward responses to better direct entities toward the appropriate resources to help understand their obligations under federal law.


Additional Information / Disclaimers

Information provided through NHTSA’s Compliance Assistance Program is not official agency action or formal agency guidance. All requests and responses are subject to the Freedom of Information Act (FOIA), 5 U.S.C. § 552. Responses do not constitute legal advice and do not create an attorney-client relationship. Questions or requests concerning, but not limited to, the following information will not be answered through the Compliance Assistance Program but rather will be re-directed to the appropriate person: ongoing litigation, ongoing investigations or enforcement actions, information on third-parties with whom NHTSA may be involved, state compliance for grant/transfer/penalty programs, and requests for specific interpretations or agency determinations on applicability/meaning of statutes or regulations.

NHTSA is not responsible for titling or registering motor vehicles or for regulating the operation of motor vehicles on public roads in the United States. That is instead the responsibility of the individual States. For assistance, please contact your State’s Department of Motor Vehicles (DMV).

Manufacturers of motor vehicles or motor vehicle equipment are encouraged to seek professional legal counsel to ensure you are meeting federal requirements.

All requests and responses are subject to the Freedom of Information Act, 5 U.S.C. § 552. To assert a claim for confidential treatment of any information submitted, you must submit a request in writing to NHTSA’s Office of Chief Counsel pursuant to 49 CFR Part 512.

You may submit your request by regular mail. However, the use of regular mail may result in a delay of the receipt of your request for confidential treatment due to the Department of Transportation’s security procedure for screening incoming mail delivered by the U.S. Postal Service.
