Title 10 — VEHICLES AND TRAFFIC Chapter 10.04 - COUNTY HIGHWAY TRAFFIC REGULATIONS
Chapter 10.40 — SPECTATORS AT SIDESHOWS, STREET RACES, AND RECKLESS DRIVING EXHIBITIONS
Alameda County Municipal Code · 2026-09 edition · updated 2026-10-01 · Alameda County
10.40.10 - Purpose.¶
The Board of Supervisors of the County of Alameda finds a need and purpose for this Ordinance based on the following findings:
A.
Sideshows cause significant damage to unincorporated Alameda County infrastructure including by harming or destroying intersection markings, street signs, poles, and other equipment; this infrastructure is critical for public safety and requires replacement after a sideshow event, which diverts resources from other critical safety improvements;
B.
Sideshows typically occur during times when violent and property crime rates are high in unincorporated areas and the Alameda County Sheriff's Office is already addressing high emergency call volumes;
Sideshows require a law enforcement response that diverts Alameda County Sheriff Office personnel from responding to these other emergencies;
C.
Sideshows create an unsafe environment for the communities in which they occur because participants and spectators drive recklessly before, during, and after the Sideshow Event. In addition, both participant drivers and spectators are often under the influence of drugs and alcohol, and have often been associated with the discharge of firearms, resulting in higher violent crime rates and vandalism;
D.
Sideshows drastically impact the quality of life in the communities where they occur by causing damage to vehicles and private and public property, reduced air quality due to the smoke released by burning rubber tires, noise pollution, and unmanageable crowds that leave behind garbage;
E.
Promoters of sideshows attract hundreds of people from outside of unincorporated Alameda County that have no stake in the community and typically plan events in neighborhoods that already suffer from poverty, poorer health, higher crime rates, historic disinvestment, and the resulting poor equity indicators.
F.
In Alameda County, vehicles at sideshows have caused great bodily injury and death to spectators.
