Subject of Possible Rule Making: WAC 204-21-020 Definitions, 204-21-130 Emergency lamps, 204-21-170 Additional lighting for snow removal, highway maintenance and refuse haulers, and 204-21-230 Lighting equipment prohibited.

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: Proposed changes to WAC 204-21-020, 204-21-130, 204-21-170, and 204-21-230 are intended to allow state, county, and municipal snow removal plow and highway maintenance vehicles, including truck-mounted attenuators, to use flashing green and white lights in addition to amber lights while at the site of operations, which would enhance visibility and provide motorists with a clear warning of hazardous equipment or active maintenance operations. The definition section would be updated to include definitions for snow removal plow and highway maintenance vehicles and provide that copies of the Society of Automotive Engineers (SAE) standards may be obtained from SAE international, rather than from Washington state patrol (WSP). Finally, minor, nonsubstantive edits would clarify existing language to reduce potential confusion and improve readability.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: WSP anticipates providing draft language to impacted stakeholders for review and input as part of the process.

Process for Developing New Rule: Agency review. WSP welcomes the public to take part in developing the rules. Anyone interested should contact the staff members identified below. At a later date, WSP will file a proposed rule making (CR-102) with the office of the code reviser. A copy of the proposal will be sent to anyone who requests a copy.
