WA HB1423

Washington Traffic Safety Commission will oversee a pilot program in cities with populations of at least 2,000 allowing automated vehicle noise enforcement cameras in designated vehicle-racing camera enforcement zones to detect violations of maximum permissible vehicle sound levels

Cameras must combine audio and visual recording technology, with audio captured only immediately before, during, and after a violation; amplified music recordings cannot be used as evidence of noise violations

Infraction fines cannot exceed $145 (adjusted for inflation every 5 years starting January 2029), with 50% reductions available for public assistance recipients; infractions are processed like parking violations and do not affect driving records

Commission must report to the legislature by January 1, 2028 on camera numbers, locations, demographic analysis of placement areas, and violation counts at each location

The pilot program and related provisions expire July 1, 2028, with an effective date of January 1, 2026
