DL 520C ETP Form – The DL 520C ETP Form is the official California DMV document used by commercial employers to voluntarily cancel their participation in the Employer Testing Program (ETP). Also known as the Employer Testing Program Voluntary Cancellation Request of Employer Number, this form allows companies to stop issuing Certificates of Driving Skill (DL 170 ETP) and exit the program without penalty.
If your business no longer needs to administer CDL drive tests in-house, downloading and submitting the DL 520C ETP PDF is the required step. This article provides everything you need: the form’s purpose, step-by-step instructions, official download link, and key details from current DMV sources.
What Is the DL 520C ETP Form?
The DL 520C ETP (Revision 10/2017) is a one-page voluntary cancellation request specifically for the California DMV’s Employer Testing Program. Employers use it when they no longer wish to participate in the ETP or issue DL 170 ETP certificates to their drivers.
Key details on the form include:
- Employer name and addresses (mailing and terminal physical)
- Administrator’s printed name, signature, and date
- Telephone number
- Reason for cancellation
- Requested cancellation effective date
The completed form must be mailed to:
Department of Motor Vehicles

Why Employers Use the Employer Testing Program (ETP) and When to Cancel?
The Employer Testing Program (ETP) lets qualified commercial employers administer the drive-test portion of Commercial Driver License (CDL) requirements instead of sending drivers to a DMV office. Approved employers can issue the official Certificate of Driving Skill (DL 170 ETP) after drivers pass vehicle inspection, basic control skills, and road tests on DMV-approved routes.
Employers commonly cancel participation when:
- The company downsizes or stops operating commercial vehicles
- Internal training programs change
- Administrative costs outweigh benefits
- The business merges or changes ownership structure
Voluntary cancellation via DL 520C ETP ensures a clean exit and notifies the DMV that the employer number is no longer active.
Who Should File the DL 520C ETP Cancellation Form?
Any authorized administrator of an ETP-participating employer can submit the form. If the original administrator is no longer available, the preparer must clearly identify their name, title, and relationship to the employer.
Cancellation does not affect previously issued DL 170 ETP certificates. The DMV, Federal Motor Carrier Safety Administration, or representatives may still audit past tests to verify compliance.

What Happens After DMV Receives Your DL 520C?
Once processed, your employer number is cancelled. You will no longer be able to:
- Issue new DL 170 ETP certificates
- Administer CDL drive tests under the program
DMV may require an on-site inspection if the employer later reapplies for a new number. Existing certified drivers keep their CDLs unless DMV finds prior testing deficiencies.
