National Highway Traffic Safety Administration

Potentially relevant material can include defect-investigation records, consumer complaints, recall records, manufacturer communications, compliance test reports, and other publicly available agency data. The significance of any individual record depends on why it was created and where it falls within NHTSA's investigation, compliance, or recall process.

Not necessarily. Manufacturers generally self-certify that their vehicles and equipment comply with applicable Federal Motor Vehicle Safety Standards, while NHTSA selects certain vehicles and equipment for compliance testing. A test report identifying an issue can prompt further analysis, but the report itself should not automatically be treated as a final agency determination of compliance or noncompliance.

The areas of expertise can overlap because NHTSA is an agency within the U.S. Department of Transportation. An NHTSA-focused expert may concentrate on federal motor vehicle safety standards, compliance testing, vehicle and equipment defects, investigations, and recalls, while a Department of Transportation expert may address a broader range of transportation regulations and operational compliance issues. The appropriate expertise depends on the regulatory and technical issues in dispute and the expert's qualifications.
