HB 1423 Washington House · 2025-2026 Regular Session

Authorizing the use of automated vehicle noise enforcement cameras in vehicle-racing camera enforcement zones.

HB 1423 authorizes cities in Washington State with populations of at least 2,000 to participate in a pilot program using automated vehicle noise enforcement cameras. These cameras would be deployed in designated "vehicle-racing camera enforcement zones" to detect vehicles exceeding maximum permissible sound levels. The Washington Traffic Safety Commission is tasked with overseeing this program and reporting on its implementation and findings to the legislature by January 2028. The section establishing this pilot program is set to expire in July 2028.

Substitute Bill → Engrossed Substitute Bill · 2 edits · Mar 7, 2025

MINOR

The bill was updated from a substitute version to an engrossed substitute version, indicating it has passed both legislative chambers. A significant new provision was added to prevent amplified music from being used as evidence in noise violation cases, clarifying that only raw vehicle noise levels should be penalized.

Scope change

The bill's scope remains focused on a pilot program for automated vehicle noise enforcement cameras in cities with at least 2,000 residents, but the enforcement criteria were narrowed by excluding amplified music as evidence.

ENFORCEMENT

Added a specific exemption stating that amplified music exceeding noise limits cannot be used as evidence of a violation, ensuring cameras only penalize actual vehicle engine noise.

The text of section (2) was modified to include the new exemption regarding amplified music while retaining the original requirements for camera usage and reporting.
