Illinois Form DSD CDTS 125 Safety Officer Notice

Illinois Form DSD CDTS 125 Safety Officer Notice – The Illinois Secretary of State (SOS) requires licensed third-party certification entities to promptly report the termination of any Safety Officer. Form DSD CDTS 125, officially titled “Notice of Termination — Safety Officer,” is the official document used for this purpose. This form helps maintain the integrity of the Commercial Driver’s License (CDL) Third-Party Certification Program under Illinois law.

This guide explains what the form is, who must file it, how to complete it correctly, where to submit it, and why timely notification matters for U.S. employers and CDL third-party testers operating in Illinois.

What Is Form DSD CDTS 125?

Form DSD CDTS 125 is an official Illinois Secretary of State document issued by the Driver Services Department, Commercial Driver Training Section. It notifies the Third-Party Certification Program Unit that a licensed Safety Officer’s employment with a third-party certification entity has ended.

The form is required pursuant to rules adopted under 92 Ill. Adm. Code 1030.60 (Third-Party Certification Program) of the Illinois Administrative Code, which implements provisions of the Illinois Vehicle Code.

A Safety Officer is an individual licensed by the Illinois Secretary of State to administer CDL skills tests (as specified in 49 CFR Part 383, Subparts G and H) to employees or members of a third-party certifying entity.

Who Must File Form DSD CDTS 125?

Any third-party certification program entity licensed by the Illinois Secretary of State must file this notice when a Safety Officer’s employment ends. This includes private companies, municipalities, fire departments, governmental agencies, and other authorized organizations that participate in the Third-Party Certification Program.

The notice must be completed and signed by an authorized representative of the third-party certification program.

Key Information Required on the Form

The official form (revised February 2023) collects the following information:

Name and complete address of the Third-Party Certification Program
Date of the notice
Full name of the Safety Officer
Safety Officer’s license number
Exact termination date
Detailed reason for termination
Signature of the authorized representative of the third-party certification program

The form is directed to:

Office of the Secretary of State
Attention: Third-Party Certification Program Unit
1800 W. Hawthorne Rd.
West Chicago, IL 60185

Why Timely Notification Is Required?

Under Illinois regulations, Safety Officer licenses are employer-specific. When a Safety Officer leaves an entity, the license authorization for that employer ends. Failure to notify the Secretary of State can create compliance issues for the third-party certification program and may affect the entity’s ability to continue administering CDL skills tests.

Proper notification also supports the Secretary of State’s oversight of the Third-Party Certification Program, which is designed to ensure that only qualified, currently employed examiners conduct skills testing for commercial drivers in Illinois.
