About our Traffic Control Supervisor program

Take your career to the next level

If you have flagging or other work zone experience, you may be eligible to become a Traffic Control Supervisor. Gain in-depth knowledge of federal and state highway construction and traffic control standards, and learn how to supervise the safe implementation of traffic control plans in work zones.

What is a Traffic Control Technician?

Those who do not meet the Washington or Oregon requirements for becoming a Traffic Control Supervisor may still attend the training, and will receive a Traffic Control Technician card upon completion. TCT training is great for engineers, inspectors, and flaggers who want to better understand the standards, documents, and realities that come up in the field. Becoming a TCT also allows you to work alongside a TCS, understand what is expected of them, and gain the experience required to do that job. If you have earned your TCT card and you submit verification of required work experience when you attend our 1-day recertification class, you can earn your TCS certification at that time.

Can I earn my TCS certification online?

Oregon TCS certification classes are offered online. Washington does not allow online TCS training—all classes must be in person. We offer in-person WA TCS classes in locations around the state. Visit our registration page for details on upcoming classes.

Glow On: High-Visibility Work Zone Safety Apparel

You may have seen road and construction workers dressed in fluorescent (often referred to as “high-visibility” or “hi-vis”) safety gear such as hard hats and vests. You probably know that these bright colors help flaggers and other road workers stand out in situations where their safety is at risk. But do you know why hi-vis colors seem to glow the way they do?
