Solano County board adopts 7‑ton limit on 18 county roads to curb truck shortcutting

The Solano County Board of Supervisors voted 4–0 on March 10 to adopt Traffic Order 438, establishing a standard 7‑ton load limit on 18 county roads to discourage large commercial trucks from using narrow local streets as shortcuts.

County resource management staff told the board the limits respond to growing complaints and engineering evidence that local pavements — many not built for sustained heavy truck traffic — have experienced accelerated cracking, rutting and pavement deterioration. Matt Tuggle, assistant director of resource management, said the shift accelerated in recent years as distribution centers and aggregate‑hauling routes increased local truck volumes.

"When the freeway gets busy, our roads sometimes become the shortest routes," Tuggle said, urging the board to funnel trucks back to interstates and legal truck routes. He added that signs will carry the placard "ag trucks exempt," and trucks with a manifest to access a property would retain legal access.

James Busick, director of resource management, said the county completed required engineering reviews and public notices. "We did pavement damage surveys, accident data review and roadway evaluations," Busick said, adding that the county had fulfilled a 60‑day notice requirement and that the California Highway Patrol (CHP) will be the primary enforcement partner.

Supervisors asked staff about implementation: how motorists and truck drivers would be informed and when signs would appear. Staff said the traffic order becomes enforceable on adoption, but signage fabrication and installation are expected to take about one to two months; staff also said the county will do outreach to local stakeholders including the Farm Bureau and notify CHP so enforcement can follow.

The traffic order lists 18 roads by name in the staff report and hearing (examples read aloud included Boyce Road, Burns Road, Goudini Road, Lake Herman Road, Maple Road, North Meridian Road and Wolfskill Road). The county noted Lake Herman Road previously had an older load limit that needed refreshing to make enforcement clear to drivers.

The board approved the order without a recorded roll‑call of individual supervisors (vote recorded as 4–0). Staff noted signage delays could produce disputes early in enforcement roll‑out and said complaint‑driven enforcement and continued coordination with CHP will be part of the implementation.

The order exempts agricultural trucks and trucks actively accessing property with a manifest; staff said those exemptions reflect agricultural needs and the county’s policy to preserve farm operations' access while protecting residential and narrow roads.
