A "vehicle propelled by an internal combustion engine"
is any vehicle designed as its principal function to carry an operator, having two wheels or more which are designed to operate in contact with the ground, the basic purpose of which vehicle is to provide transportation for one or more persons, and which vehicle is propelled or derives its source of power from an internal combustion engine. For the purposes of this chapter, "vehicle" includes, but is not limited to, the following vehicles: motorcycle, motor-drive cycle, minibike, trail bike, motor scooter, jeep, and dune buggy.
(Ord. 659 § 1, 1971)
It is unlawful for any person to operate any vehicle as defined in this chapter on private property without the prior written consent of all the owners and all the persons in lawful possession of the real property, unless the owners of property have posted the property permitting such use. Upon demand to leave given to the operator of any vehicle herein described, by the owner, or authorized representative of the owner, or person in lawful possession of the real property, no person to whom such demand is addressed shall thereafter operate a vehicle as described in this chapter on such private property, except as is necessary to immediately quit the property by the shortest route and time reasonably available.
Provided, however, that the prohibitions of this chapter shall not include or apply to the following:
(a) 
The operation of a vehicle having a valid California vehicle registration by any person possessing a valid California operator's license, upon a public street or highway;
(b) 
A public officer or employee acting within the scope of his employment;
(c) 
The operation of such vehicle upon driveways, parking lots, race courses, or other places where the public is invited to operate such vehicles so long as such vehicles are operated in the reasonable and ordinary manner customary for such use.
(Ord. 659 § 1, 1971)
(a) 
It is unlawful for any person to operate any vehicle as defined in this chapter on private property within the city without a U.S. Forestry Service or state of California approved spark arrestor or a noise muffling device approved by the state of California.
(b) 
It is unlawful for any person to operate any vehicle on private property within three hundred feet of the exterior boundaries of any residential property, except where reasonably necessary upon his own property, or property of others over which a lawful easement right is owned, for purposes of ingress or egress.
(c) 
It is unlawful for any person to operate, within the city, any vehicle beyond three hundred feet of the exterior boundary of any residential property (whether on his own property or that of others) in such manner or with equipment on the vehicle that the volume of the exhaust, sound, or motor noise is audible to the extent that the noise volume is so loud, raucous or jarring as to be disturbing or a nuisance to the peace or quiet of any adjacent neighborhood or a person residing in an adjacent neighborhood or conducting a lawful business therein. There shall be a rebuttable presumption of compliance with the equipment requirements of this subsection if the vehicle is determined to be in compliance with subsection (a) above.
(d) 
It is unlawful for any person to operate within the city any vehicle as defined in this chapter in such a manner as is reasonably likely to disturb the peace of any neighborhood or person or as reasonably likely to constitute a nuisance to any neighborhood or person by reason of dust, smoke or fumes.
