– Test Facility: Manufacturers must have access to a test facility equipped with the necessary equipment to conduct the required tests.

### Steps for Obtaining a DOT Certificate

Obtaining a DOT certificate involves several steps:

1. Submit an Application: Manufacturers must submit an application to the National Highway Traffic Safety Administration (NHTSA) along with the following documents:
– Copies of the applicable FMVSS standards
– Descriptions of the quality control system
