Obtaining a Commercial Driver’s License

    • Schedule and pass the skills test, including a pre-trip inspection, basic vehicle control, and a road test.

  4. Comply with Additional Endorsements: Depending on the type of vehicle you intend to drive, additional endorsements may be required (e.g., transporting hazmat materials or driving a school bus).
