It takes special skills, training, and aptitude to safely operate large vehicles. We issue commercial driver’s licenses (CDLs) to ensure that drivers meet our high standards for operating commercial motor vehicles.

Drug and Alcohol Clearinghouse (DACH):

Beginning November 18, 2024, the Department of Motor Vehicles (DMV) will implement federal DACH requirements.

DMV is prohibited from issuing, replacing, renewing, transferring, or upgrading a commercial driver’s license (CDL) or commercial learner’s permit (CLP) for any driver with a “prohibited” status in DACH.

Additionally, DMV is required to remove the commercial driving privileges of CLP or CDL holders who have a “prohibited” status in DACH, until completion of the return-to-duty process.

Entry Level Driver Training (ELDT) CDL Applicants:

Successful completion of Entry Level Driver Training (ELDT) conducted by a registered training provider listed on the federal Training Provider Registry (TPR) is required for commercial driver’s license (CDL) applicants who are:

  • Obtaining an original CDL (Class A or B);
  • Upgrading an existing Class B CDL to a Class A CDL; or
  • Obtaining a School Bus (S), Passenger (P), or Hazardous Materials (H) endorsement

In addition to the federal requirements, when applying for an original CDL (Class A or B) in California, the applicant must complete a minimum of 15 hours of behind-the-wheel training and submit a California Commercial Driver Behind The Wheel Training Certification (DL 1236) to the DMV as proof of completion prior to the issuance of their CDL.

In either scenario, you need to hold a CDL in order to drive a CMV.
