If by "car" you mean "card," the answer is no. The Transportation Worker Identification Credential (TWIC) is required by the Maritime Transportation Security Act for workers who need access to secure areas of maritime facilities and vessels. It is also sometimes used at other facilities such as oil and gas refineries, and chemical plants to allow unescorted access to secure areas of the facility. TSA conducts a security threat assessment (background check) to determine a person’s eligibility for the card, and if the person is found to not be a risk they are granted the credentials for unescorted access.
This has nothing whatsoever to do with the required knowledge to transport hazardous materials.
