Yavapai County Board of Supervisors Approves Ordinance Restricting "Jake Brake" Noise in Residential Areas
YAVAPAI COUNTY, AZ — The Yavapai County Board of Supervisors officially approved Ordinance 2026-1, a new measure designed to significantly reduce disruptive traffic noise and protect the quality of life in unincorporated residential communities. The ordinance strictly prohibits the use of engine and compression brakes—commonly known as "Jake Brakes"—within specified residential areas.
While engine braking is a standard practice used by commercial vehicles to slow down safely, the mechanical decibel level it produces in close proximity to neighborhoods has become a growing concern for local residents. Ordinance 2026-1 establishes a clear framework to address these disruptions, authorizing the installation of roadside signage to alert drivers and allowing for law enforcement to issue a $250 civil forfeiture penalty for violations.
"Our goal is to balance the needs of commercial transit with the right of our residents to quietly enjoy their homes and properties," said the Yavapai County Board of Supervisors Chair Brooks Compton. "By establishing these targeted zones and providing clear signage, we can keep our neighborhoods peaceful while maintaining safety."
The ordinance designates specific restriction zones across several communities where noise issues have been most prevalent. The prohibited zones include targeted segments within Williamson Valley, Skull Valley, Prescott, Iron Springs, Ho-Kay-Gon, and Cornville.
Yavapai County Public Works will begin deploying official regulatory signage at the entry points of these designated zones in the coming weeks. The ordinance takes effect immediately, and drivers of heavy machinery and commercial vehicles are encouraged to utilize standard braking mechanisms when traveling through these residential corridors.
