Repairs and services

Automotive repair dealers perform repairs and services essential to helping consumers maintain and repair their vehicles. In all transactions, automotive repair dealers must comply with the Automotive Repair Act (Act) and related laws and regulations. At its core, the Act establishes requirements for automotive repair transactions between auto shops and consumers. It also establishes requirements and standards for certain repairs and services to help automotive repair dealers ensure the quality and safety of their work.

Write It Right: Documentation and authorization


Automotive repair dealers must provide an estimate and obtain authorization from the consumer before beginning any repairs, obtain additional authorization if additional repairs are needed, and provide a final invoice describing all repairs performed and parts provided in terms the consumer can understand. For helpful quick-reference information on these requirements and other obligations relating to automotive repair transactions, check out BAR’s Write It Right. A longstanding resource for licensees, Write It Right—available as an online guide—covers estimates, authorization, invoices, and more. You can also request a Write It Right presentation by a BAR representative for your next staff meeting or event.
