DL 520 – Employer Testing Program Application (California DMV)

The DL 520 is the California Department of Motor Vehicles (DMV) application used by employers to obtain an employer number for the Employer Testing Program (ETP). This program allows qualified organizations to issue Certificates of Driving Skill (DL 170 ETP) to employees who operate motor vehicles in safety‑sensitive positions.

What is the DL 520 Form?

The DL 520 form collects essential information about your business, the types of testing you will conduct, and your compliance with California Vehicle Code sections related to employer‑run testing programs. Once approved, you receive an employer number that authorizes you to manage driver‑skill testing under the ETP.

Who Must Complete the DL 520?

• Employers in California who need to test employees for driving‑skill certification (e.g., transportation, construction, utilities).
• Companies that wish to issue DL 170 ETP certificates to qualified drivers.
• Any organization that conducts mandatory drug, alcohol, or skills testing required by state law.
