Commercial Driver License - Hazmat

  1. Do I have to do anything different on the drive test if I have passed the written examination to haul Hazmat prior to my taking the skills test examination?

    • No. Throughout the test the applicant will NOT be driving as if they are carrying a Hazmat load. Because the vehicle is not properly marked to carry Hazmat, that applicant will NOT be stopping at any railroad crossings for the sole purpose of such load.
    • All 1st time Hazmat Endorsements will have to comply with ELDT requirements prior to taking the required written test.
