AB 98: Truck Routes in Unincorporated San Bernardino County
Overview
California Assembly Bill 98 (AB 98) is a California law, signed on September 29, 2024, that regulates truck traffic by designating safe and efficient truck routes. The goal of the truck routes is to minimize the impact of heavy vehicles on sensitive areas and maintain safe and efficient movement of goods. AB 98 provides a framework for identifying and enforcing approved truck routes. San Bernardino County adopted regional truck routes on December 16, 2025, completing Phase I of the AB 98 Truck Routes in Unincorporated San Bernardino Countyproject. The County is now in Phase II of the project, which focuses on refining truck routes as needed, expanding public awareness and education of truck routes, and continuing to gather community feedback.
Key Requirements
AB 98 introduces specific requirements for assigning truck routes and adopting them into the Circulation Element (Transportation and Mobility Element) of the General Plan (to as Countywide Plan).
Truck Route Adoption Requirements:
- Truck Routes must be adopted by January 1, 2026, in the Warehouse Concentration Region (WCR) which includes unincorporated San Bernardino County.
- Truck Routes must maximize the use of major highways and only utilize commercial roads when necessary.
- Truck Routes will be provided in a Geographic Information System (GIS) format and will be made publicly accessible.
- Conspicuous signage will be installed to identify truck routes, truck parking, and appropriate idling locations.
- The County must provide opportunities for public input and participation.

Draft Signage Plan
Send comments/questions to: Anthony Pham, Engineering Manager, Anthony.Pham@dpw.sbcounty.gov
We are sharing the draft signage plan for public review and comment. Please note that truck route sign types, placement and post locations are governed by the California Manual on Uniform Traffic Control Devices(CAMUTCD). These standards are established at the state and federal levels and are not subject to modification by County.
We welcome feedback on elements of the plan that are eligible for adjustment and look forward to receiving your comments.

Frequently Asked Questions
Truck routes dictate where large trucks are allowed to drive.
The warehouse concentration region includes the counties of Riverside and San Bernardino, and the cities of Chino, Colton, Fontana, Jurupa Valley, Moreno Valley, Ontario, Perris, Rancho Cucamonga, Redlands, Rialto, Riverside, and San Bernardino. The deadline for truck route adoption in the warehouse concentration region is January 1, 2026. Jurisdictions outside the warehouse concentration region have until January 1, 2028 to adopt truck routes.
Jurisdictions must do the following:
- The Transportation and Mobility Element must be updated to include designated truck routes that avoid sensitive receptors. Currently, the County only identifies federal and state truck routes.
- Maximize the use of highways as preferred routes for truck routes. Truck Routes may also include arterial roads, major thoroughfares, and predominantly commercially oriented (50 percent of the properties fronting the road within 1,000 feet are designed for commercial or industrial use) local streets as needed.
- Engage with the community to hear concerns and gather input.
- Post signage identifying truck routes, truck parking, and truck idling.
- Provide a GIS map of designated truck routes to the public
AB 98 defines designated routes trucks must use which may change some truck traffic patterns in the county. Truck routes are designed to keep trucks on main roads and away from residential areas when possible.
AB 98 requires jurisdictions to place conspicuous signage identifying truck routes and addressing both parking and idling.
The county worked with state agencies, transportation experts, and community members to identify truck routes that minimize impact on residential areas. Experts evaluated existing truck traffic, analyzed truck route criteria, and incorporate public feedback. Proposed truck routes must comply with the following:
- Truck routes must maximize the use of freeways and highways.
- Major or minor collector streets and roads that predominantly serve commercially oriented uses must be used for truck routes only when strictly necessary.
- Trucks must be routed to minimize exposure to sensitive receptors.
Not necessarily. AB 98 requires that truck routes first make maximum use of highways, major roads, and only use local roads when necessary.
No. AB 98 is a state mandate, and San Bernardino County is required to comply.
Smaller, local delivery trucks are not restricted to truck routes by the legislation. The truck routes only apply to the heavy duty, large trucks.
