SENATE COMMITTEE ON TRANSPORTATION
Majority Report: That Substitute Senate Bill No. 5494 be substituted therefor, and the substitute bill do pass.
Signed by Senators Haugen, Chair; Gardner, Vice Chair; Benton; Eide, Finkbeiner, Horn, Jacobsen, Johnson, Kastama, McAuliffe, McDonald, Oke, Patterson, Prentice, T. Sheldon, Shin and Swecker.
Staff: Jennifer Ziegler (786-7316)
Background: In 1977, the Legislature enacted laws to make motor vehicle equipment requirements consistent with federal law. Currently, every motor vehicle must be equipped with a muffler in good working order and in constant operation to prevent excessive or unusual noise. Current law also prohibits modification of an exhaust system of a motor vehicle in a way which will make the engine noise louder than the noise emitted by the muffler originally installed on the vehicle.
Summary of Substitute Bill: Modification of the exhaust system of a motor vehicle is prohibited if the modification violates Society of Automotive Engineer's standards regarding adequate muffling devices. This prohibition does not apply to passenger vehicles operated off highways in an organized racing or competitive event conducted by a recognized sanctioning body.
Substitute Bill Compared to Original Bill: Specific standards from the Society of Automotive Engineers are outlined in the bill.
Appropriation: None.
Fiscal Note: Not requested.
Effective Date: Ninety days after adjournment of session in which bill is passed.
Testimony For: Individuals who are interested in high performance vehicles are concerned that current law regarding muffler noise is subjective and does not set out clear standards. Modification of mufflers is often done to enhance performance, not to increase noise. People who participate in sanctioned races want to be able to drive their cars home.
Testimony Against: None.
Testified: Senator Jacobsen, prime sponsor; Matthew Ahl, student.
