Traffic Control Supervisor certification

Traffic Control Supervisors oversee the equipment and crews who help redirect traffic in work zones. We offer classes for Oregon, Washington State, and Idaho Traffic Control Supervisor or Traffic Control Technician certification.

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.

When working with one or more flaggers, coordination and communication are essential for maintaining smooth and safe traffic flow. Here's a guide to effectively working as a team while controlling traffic.

Flagger signaling with a red flag

Flagging is a challenging and hazardous job that requires strong mental and physical abilities, and takes place in tough work environments. Wearing the right combination of hi-visibility apparel and workwear is one of the keys to keeping yourself safe in the work zone.

Are you sending the right signals?

One of the most important skills you’ll use when working as a flagger is signaling with the STOP/SLOW paddle. Here are a few tips to get you up to speed, while slowing traffic down.

Flagger clothing requirements for Washington State

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.
