9.31.010 - Statement of purpose and intent.¶
The Council for the City of Riverside finds and declares that pursuant to California Vehicle Code Section 23109, motor vehicle speed contests and exhibitions of speed conducted on public streets and highways are illegal. Motor vehicle speed contests and exhibitions of speed are more commonly known as street races or drag races.
Streets within the City of Riverside have been the site of continuing and escalating illegal street racing over the past several years. Such street racing threatens the health and safety of the public, interferes with pedestrian and vehicular traffic, creates a public nuisance, and interferes with the right of private business owners to enjoy the use of their property within the City of Riverside. The illegal street races occur on a regular basis on various streets within the City. Hundreds of racers and spectators gather on these streets late at night and in the early morning hours, blocking the streets and sidewalks to traffic, forming a racetrack area, placing bets, and otherwise encouraging, aiding, and abetting the racing process.
Illegal street racers accelerate to high speeds without regard to oncoming traffic, pedestrians, or vehicles parked or moving nearby. The racers drive quickly from street to street, race for several hours, and then move to other locations upon the arrival of the police. Those who participate in this illegal activity are very sophisticated, using cell phones, police scanners, and other electronic devices to communicate with each other to avoid arrest. They also use the Internet to provide information on where to race, and give advice on how to avoid detection and prosecution. Traffic accidents, property crimes, and calls for police service have increased dramatically.
In most cases, illegal street races attract hundreds of spectators. The mere presence of spectators at these events fuels the illegal street racing and creates an environment in which these illegal activities can flourish. This section makes evidence of specified prior acts admissible to show the propensity of the defendant to be present at or attend illegal street races, if the prior act or acts occurred within three years of the presently charged offense. This section is adopted to prohibit spectators at illegal street races with the aim of significantly curbing this criminal activity. The section targets a very clear, limited population and gives proper notice to citizens as to what activities are lawful and what activities are unlawful. In discouraging spectators, the act of organizing and participating in illegal street races will be discouraged.
