Amador County, CA Parking Rules: Commercial Vehicle Restrictions (2026)

Unincorporated Amador County does not have a blanket ordinance prohibiting commercial trucks from parking on residential streets. Where it does regulate commercial and heavy vehicles, it does so through Title 10, Chapter 10.24 (Weight Restrictions on Vehicles), which limits travel by weight on specific infrastructure. The code prohibits more than ten thousand pounds on certain county bridges (over Sutter Creek near Ione and over Jackson Creek near Buena Vista); bars commercial vehicles over fourteen thousand pounds gross weight on the Carbondale-Plymouth County Road No. 65 bridge and on Williams Road (County Road No. 182); and prohibits commercial vehicles exceeding twenty thousand pounds gross weight on New York Ranch Road, Fiddletown, Jackson Valley, Martin and Lancha Plana roads. Other named roads carry a 20,000-pound total vehicle-and-load limit, and Defender Grade Road and Joyce Road carry a fourteen-ton limit. The chapter's note cites California Vehicle Code Section 35780 et seq. for the permit process to move overweight or oversize vehicles. Within the county parking areas, the loading exception (Section 10.12.130) lets commercial vehicles stop to load or unload for up to thirty minutes. For ordinary parking of a commercial vehicle elsewhere, the California Vehicle Code controls. Drivers of heavy or oversize loads should secure a county transportation permit under Chapter 10.44 where required.
