Work Zone Traffic Control Supervisor Training:

Work Zone Traffic Control Supervisor (TCS) Classes:
WSDOT offers a two and a half day Work Zone Traffic Control Supervisor course and a one day re-certification class.

Certification Information:

WSDOT does not process or issue certifications for non-WSDOT employees. This is done by each training organization listed below. The steps needed to become a certified Traffic Control Supervisor are as follows:

  1. Have 2000 hours of traffic control experience. This experience may come from working with traffic control on a maintenance or survey crew. It may include being a project inspector on construction projects requiring traffic control. An employee developing or reviewing traffic control plans gains traffic control experience as well. The combination of the above allowable experience, in traffic control, must equal at least one year, or 2000 hours. This experience is required to become a certified Traffic Control Supervisor.
  2. Documentation of traffic control experience. To document the traffic control experience, a person must have two letters of recommendation that verify their work with traffic control. The letters must not come from the employee attempting
    to become a certified TCS. One letter needs to come from a supervisor, either current or past. The other letter must come from a resource that knows the employee's present or past work experience.
  3. Take the Work Zone Traffic Control Supervisor's course.
    Each person must attend the two and one-half day course and pass the written test with at least 80 percent. After the course has been taken, the test passed, and the experience accepted, a TCS card will be issued to the employee.
  4. Possess a valid Flagger Certification Card. Approved states are: Idaho, Montana, Oregon and Washington.

TCS Recertification requirements:
To recertify you must successfully complete the 1-day course and have a score of 80 percent or better on the recertification exam.
To qualify to attend the recertification course you must submit the following documents:

A copy of your current state approved flagging card. Approved states are: Idaho Montana, Oregon and Washington.
A copy of your current Traffic Control Supervisors Certificate.

NOTE: There is a 6-month grace period after expiration to take the 1-day recertification. However, there is no grace period for working with an expired card.

TCS Training for non-WSDOT employees is available through:

WSDOT Traffic Control Plan Design (TCPD) Training:

(Open to WSDOT Employees and Local Agency Personnel)

This 2 day class focuses on the policy, process and standards for developing a Transportation Management Plan (TMP) and design of Traffic Control Plans (TCP) for roadway construction projects. Lectures cover topics such as TMP requirements, assessing work zone impacts, developing traffic control strategies, traffic control standards, devices and types of traffic control plans to include in the PS&E.
