Full Breakdown

12 of the Stanislaus County Code creates two types of loading zones on named unincorporated road sections. 020 then lists thirteen individual yellow-zone sites, from Daly Avenue and Gilmore Avenue to Ninth Street and Poppy Glen Road. on school days only, matching drop-off and pickup traffic at nearby schools; the rest apply without a time limit once posted. 040 lists eight white-zone sites including Bonita Avenue, Oakdale Road, Keller Street and Enterprise Way. As with the county's other curb-color ordinances, the restriction only takes effect once the county has actually painted the curb or posted a sign at the specific site named in the ordinance, the color and the location must match what the code lists.

Both lists have been amended repeatedly since the 1980s as new commercial sites were added or repealed; the yellow-zone list was last updated in 2005 and the white-zone list in 2012. Because the chapter governs the unincorporated county only, loading zones on streets inside Modesto, Turlock, Ceres or the county's other cities are set by that city's own code.

Violations & Fines

Parking in a marked loading zone for longer than the posted purpose allows, or parking there outside the loading-only use entirely, is a Vehicle Code curb-color violation, cited by the Sheriff's Office. On Hawthorne Street and Elm Street, parking in the zone outside the 8 a.m.–3:30 p.m. school-day window, or for any purpose other than school loading, is likewise citable once the zone is signed.

Frequently Asked Questions

What does a yellow curb mean in Stanislaus County?
Under § 11.12.010, a yellow-painted curb at one of the listed sites means stopping is allowed only to load or unload passengers or freight, for the time specified at that location; parking there for any other purpose is a violation once the county has posted the zone.
Are any loading zones time-limited?
Yes. The Hawthorne Street and Elm Street yellow zones, both near Modesto-area schools, operate only from 8 a.m. to 3:30 p.m. on school days; outside those hours the curb reverts to ordinary parking rules under the rest of Title 11.
What is the difference between a yellow and a white zone here?
Yellow zones under § 11.12.010 are for loading or unloading passengers or freight; white zones under § 11.12.030 are reserved specifically for loading and unloading passengers, not freight, at sites such as Bonita Avenue and Oakdale Road.
