Full Breakdown

Section 12.08.660 of the county's General Ordinance Code makes it a misdemeanor to use a sidewalk built along a public roadway in unincorporated Alameda County with mules, horses, or any kind of vehicle, except when the movement is simply to enter or leave the adjoining premises. The rule sits in Chapter 12.08's roadway-use regulations, which govern county-maintained public roadways in the unincorporated area, not the sidewalks of Oakland, Berkeley, or the county's other thirteen incorporated cities, which enforce their own municipal codes.

Violations & Fines

A conviction is punishable by a fine of up to one hundred dollars or up to five days in county jail, per Section 12.08.660.
