TSA approvals allowing drivers to apply for a hazardous material endorsement, expires five years from the date the approval was issued. The length of the TSA approval must match or exceed the new expiration date of the driver license being issued. If the TSA approval period is less than the expiration date of the license being issued, you must apply for a new federal background record check to maintain the hazardous materials endorsement on your driver's license.
Drivers are also reminded that fingerprint and background checks take 30-60 days to complete. Drivers wishing to renew their hazardous materials endorsement should begin the application process at least 60 days before their license expires to allow enough time to meet all requirements.
