Summary

Union City bars driving motorcycles, scooters, or minibikes on any property that isn't a public or City-approved private street, a rule the Council adopted specifically to curb excessive off-road vehicle noise.

No person shall drive a motorcycle or motor-driven vehicles, as such vehicles are defined in the California Vehicle Code, including, but not limited to, motor scooters, motorbikes, and minibikes, upon any property which is not a public street, or a private street approved by the City.

A. Exceptions. This section shall not apply where such vehicle is being driven upon property by the resident, regular occupant, or authorized visitor for the purposes of ingress or egress to such property.

B. Declaration Regarding Necessity for Section. This section is declared to be necessary in order to protect the public health, safety, peace and general welfare of the citizens of the City for the following reasons:

1. Noise emitted by motorcycles, motor-driven cycles and similar vehicles creates a substantial nuisance far in excess of other contributions to the normal noise level of the surrounding environment.

2. Such activity is primarily conducted as a recreational or leisure time pursuit, often by large numbers of drivers and passengers, and has no relationship to the economic use of the land or property being utilized by the owners.

3. Often such activity is a trespass upon private or public property.

4. Existence of such activity creates undue hardship on residents and citizens throughout the community due to excessive noise conditions.

Full Breakdown

Union City Municipal Code § 9.36.025 makes it unlawful to drive a motorcycle or other motor-driven vehicle, including motor scooters, motorbikes, and minibikes, on any property that is not a public street or a City-approved private street. The only exception is a resident, regular occupant, or authorized visitor driving for ingress or egress to that property. The City Council adopted the ban after finding that noise from motorcycles and similar vehicles creates far more of a nuisance than ordinary background noise in the area, and that such riding is primarily a recreational or leisure-time pursuit, unrelated to any economic use of the land, and often trespasses on private or public property.

Violations & Fines

Driving a motorcycle or minibike off a public or approved street outside the ingress/egress exception is enforceable as a public-peace violation under Chapter 9.36, Disturbing the Peace.

Frequently Asked Questions

Can I ride a dirt bike or minibike on my own property in Union City?
Only to enter or leave the property as a resident, regular occupant, or authorized visitor: general recreational riding on private property that isn't a City-approved street is banned under § 9.36.025.
Why does Union City single out motorcycles for this ban?
The Council's own findings state that motorcycle and minibike noise creates substantially more nuisance than ordinary background noise, and that such riding is primarily a recreational pursuit unrelated to any economic use of the land.
