Agency rule making

State agencies adopt rules to carry out state and federal laws. Learn about the rule-making process and current rule-making activity.

Rule-making process

WSDOT and the Washington State Transportation Commission (WSTC) file all proposed, emergency, amended, new, and repealed rules with the Office of the Code Reviser. The Office of the Code Reviser publishes them in the Washington State Register (WSR). Adopted rules become part of the Washington Administrative Code (WAC).

WSDOT and WSTC are committed to developing and adopting rules that are necessary, fair, understandable, and consistent. WSDOT's Business Support Services Division oversees and provides information about rules administered by WSDOT and WSTC. The Business Support Services Division is the official WSDOT and WSTC liaison with the Office of the Code Reviser and the Joint Administrative Rules Review Committee (JARRC).

The Administrative Procedure Act (APA) is the state law that outlines the standards that WSDOT and WSTC must follow to adopt a rule. The Regulatory Fairness Act requires WSDOT and WSTC to analyze the impact of their rules on small businesses.

Slow down – lives are on the line.

Excessive speed was a top cause of work zone collisions in 2024.

Phone down, eyes up.

Work zones need our undivided attention.

It's in EVERYONE’S best interest.

96% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
