California On-Highway Diesel Averages $7.219 per Gallon Amid State Contracts Mandating Fleet Compliance
The average price for on-highway diesel in California reached $7.219 per gallon on March 30. This marks a 44.7% increase from $4.99 per gallon on March 2. Professional drivers operating in the state face direct impacts from this rise, as fuel costs represent a significant portion of operating expenses for long-haul and regional routes.
California’s diesel market consistently commands higher prices than the national average due to state-specific taxes, environmental regulations, and refining constraints. For truck drivers, this escalation compresses margins on loads, particularly for independent operators and small fleets without hedging contracts or bulk purchasing agreements.
Coinciding with this price surge, the California Department of General Services has issued multiple bid advertisements for public works projects. These contracts highlight regulatory requirements that affect trucking fleets, especially those using off-road diesel equipment. Every listed project mandates submission of a Certificate of Reported Compliance (CRC) for any fleet vehicles subject to the California Air Resources Board (CARB) In-Use Off-Road Diesel-Fueled Fleets Regulation, Section 2449(i), Title 13, California Code of Regulations.
The CRC requirement applies prior to contract execution for contractors and listed subcontractors. It ensures compliance with CARB rules aimed at reducing emissions from off-road diesel engines used in construction and maintenance work. Fleets retaining such vehicles must provide valid CRC copies if those vehicles support contract work. Additional details on the regulation are available through CARB resources.
These stipulations underscore the operational realities for drivers and fleet managers in California. Many construction-related hauls involve off-road equipment like excavators, loaders, and generators powered by diesel. Drivers pulling equipment trailers or fuel for these sites must align with prime contractors who secure state work, navigating the same compliance hurdles.
- Projects are restricted to small business and micro business contractors certified by the California Department of General Services, Office of Small Business and DVBE Services, per Government Code 14838.7.
- Required contractor licenses vary by project: B for structural and sallyport work, C-10 for electrical installations, A for general engineering like lake repairs.
- All include health and safety provisions requiring adherence to the most restrictive federal, state, local, or Department of General Services mandates, with compliance costs borne by contractors.
One project, the Santa Clara Structural Investigation Project (Project 5074A, Contract 23-187402) at the Department of Motor Vehicles Santa Clara Field Office, requires a mandatory pre-bid site inspection on February 28, 2024, at 7:00 a.m. at 3665 Flora Vista Ave., Santa Clara. Bidders must attend fully and sign in/out to qualify.
Electric vehicle infrastructure features prominently in two California Department of Corrections and Rehabilitation (CDCR) bids. The Lancaster project (Contract 25-274362, Project 13765) in Los Angeles County mandates a virtual pre-bid on October 7, 2025, via Microsoft Teams, with security clearance required by September 30, 2025. Similarly, the Pleasant Valley State Prison project (Contract 25-289268, Project 13836) in Coalinga, Fresno County, involves installing and connecting EVSE infrastructure, including wiring and testing. Its virtual pre-bid is January 20, 2026, with clearance by January 6, 2026.
Other projects include Ramer Lake Repair (Contract 24-255652, Project 12385) for the Department of Fish and Wildlife in Imperial County, with an in-person pre-bid on June 3, 2025, at the site. Sealed bids due June 17, 2025. The Sallyport Expansion (Contract 25-282872, Project 6723) at Porterville Developmental Center in Tulare County requires a pre-bid on November 13, 2025, at 320 Palm Way, with security clearance by November 10, 2025. Bids due December 9, 2025.
Bid documents for all projects are downloadable via the Department of General Services portal. Search by project number under “Start Search,” then access the event package. Electronic submissions apply to some, while others require sealed bids at 707 Third Street, West Sacramento, CA 95605. Preliminary bid tabulations are emailed post-opening.
For truck drivers, these developments signal sustained demand for material hauls to state sites amid high diesel costs. Fleets must maintain CRC compliance for off-road assets to bid on or support this work, adding administrative layers to fuel-challenged operations. Professional drivers hauling for certified small businesses gain visibility into upcoming projects across structural, electrical, environmental, and infrastructure categories.
California’s regulatory environment continues to shape fleet strategies. The CRC process verifies annual reporting on off-road diesel fleet inventories, PM retrofits, and best available control technology compliance. Non-road diesel vehicles over 25 horsepower, used more than 120 hours yearly, fall under these rules, relevant for drivers servicing construction logistics.
As diesel prices fluctuate, state contracts provide a steady pipeline of work for compliant operators. Drivers monitoring these opportunities can position for loads to sites in Santa Clara, Lancaster, Coalinga, Imperial, and Porterville counties. With bids spanning 2024 to 2026, planning around pre-bid deadlines and license needs is essential.
