AB 855 adds Section 34521 to the California Vehicle Code and requires the Office of Emergency Services (OES) to develop and post an action plan for responding to electric commercial motor vehicle battery fires by January 1, 2027. The statute lists eight topic areas the plan must address, from assessing high-voltage hazards to mitigating battery reignition and reducing wildfire risk.
The bill matters because electric commercial vehicles introduce distinct hazards — thermal runaway, toxic emissions, and prolonged reignition risk — that existing crash and fire protocols do not systematically address. A statewide, cross‑agency plan would provide common practices for first responders, transportation agencies, fleet operators, and communities, but the bill leaves key implementation details, funding, and enforcement unanswered.
At a Glance
What It Does
The bill requires OES to develop and publish online an action plan focused on electric commercial motor vehicle battery fires, with a January 1, 2027 deadline. The plan must include best practices covering eight enumerated areas such as high‑voltage hazard assessment, wildfire risk reduction, and minimizing roadway closures.
Who It Affects
The plan affects state and local emergency response agencies, Caltrans and other roadway owners, electric commercial truck and bus manufacturers, fleet operators and drivers, labor organizations, and communities near crash sites. First responders and towing/salvage operators will rely on the plan operationally.
Why It Matters
Electric commercial vehicles present different fire behavior and public‑health risks than fossil‑fuel vehicle fires; a coordinated, statewide set of practices could reduce unsafe on‑scene decisions, shorten closures, and limit environmental impacts. But because the bill is guidance‑oriented, its practical effect depends on interagency coordination, adoption, and resources.

What This Bill Actually Does
AB 855 inserts a single new section into the Vehicle Code that directs the Office of Emergency Services to prepare and post an online action plan specifically for battery fires involving electric commercial motor vehicles. The statute sets a firm deadline (January 1, 2027) and enumerates the subject matter the plan must cover, rather than prescribing technical fixes or operational mandates itself.
The required plan content is broad: agencies must describe practices for assessing high‑voltage and fire hazards after collisions; protecting drivers, first responders and bystanders; evaluating health risks from released toxins and setting safety buffers; reducing wildfire ignition risk; preventing structural harm to bridges and overpasses; using scarce resources efficiently (explicitly mentioning water and air support); minimizing roadway closure time; and addressing battery reignition. That list skews operational — it tells agencies the problems to solve but leaves the specific tactical standards to the plan-writing process.AB 855 also requires OES to consult with a set of named stakeholders — the Office of the State Fire Marshal, the California Highway Patrol, the Department of Transportation (Caltrans), electric truck manufacturers, and labor organizations — and allows optional consultation with other state or federal agencies.
The statute therefore mandates an interagency and public‑private discussion but does not assign enforcement authority, set mandatory training or equipment standards, or appropriate funds for implementation.In practice, the action plan will need to knit together technical guidance on high‑voltage isolation, thermal‑runaway suppression, post‑extinguishment monitoring for reignition, hazardous runoff and air‑quality containment strategies, structural inspection triggers for bridges, and triage protocols to reopen highways safely. Because the bill is prescriptive about topics but nondirective about methods, the value of AB 855 will hinge on how thoroughly OES coordinates with fire, transportation, and industry partners and whether the plan is translated into funded training, equipment acquisitions, and local adoption protocols.
The Five Things You Need to Know
AB 855 adds Section 34521 to the Vehicle Code and requires the Office of Emergency Services to develop and post an action plan for electric commercial motor vehicle battery fires by January 1, 2027.
The statute specifies eight minimum topics the plan must address, including high‑voltage hazard assessment, public‑health safety buffers, wildfire risk reduction, preventing structural damage to bridges, and mitigation of battery reignition.
OES must consult with named stakeholders — the Office of the State Fire Marshal, California Highway Patrol, Department of Transportation (Caltrans), electric truck manufacturers, and labor organizations — during plan development.
The bill allows OES to consult additional state or federal agencies but does not create enforcement powers, funding streams, or mandatory operational standards tied to the plan.
The statutory language contains drafting inconsistencies (mixed references to 'department' and 'office' and duplicated terms) and leaves key definitions and resource allocations unspecified, which could complicate implementation.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
OES required to publish an action plan by Jan. 1, 2027
Subsection (a) assigns responsibility for the plan to the 'department Office of Emergency Services' and imposes a clear deadline to post the plan online. Practically, this obliges OES to convene partners, draft guidance, and make the document publicly available by the statutory date. The provision is procedural — it sets a product and a deadline rather than obligating specific actions in the field.
Minimum content: eight operational priorities
Subsection (b) lists eight discrete areas the plan must cover, from high‑voltage hazard assessment and responder safety to wildfire reduction and minimizing roadway closures. Because the bill prescribes topics instead of technical standards, OES must translate those priorities into concrete procedures, decision trees, and resource plans — for example, describing when to monitor for reignition, what constitutes a 'safety buffer,' or how to balance water use against environmental runoff.
Mandatory stakeholder consultations
Subsection (c) requires OES to consult with specific stakeholders: the Office of the State Fire Marshal, CHP, Caltrans, electric truck manufacturers, and labor organizations. That list signals the bill's emphasis on interagency and industry input for operational feasibility and responder safety; it also creates an expectation that the final plan reflects competing operational perspectives (safety, mobility, supply‑chain, and labor).
Permissive consultations with other agencies
Subsection (d) gives OES discretion to consult any relevant state or federal agency. That catchall enables engagement with public‑health departments, environmental regulators, federal DOT or NHTSA, and federal emergency agencies, which will be important if the plan needs technical standards, air‑quality thresholds, or interoperability with existing federal guidance. The provision preserves OES’s flexibility but does not obligate such consultations.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Local and state first responders (firefighters, EMS, CHP officers) — The plan would provide common best practices for approaching HV systems, extinguishing thermal runaway, and managing reignition risk, improving on‑scene safety and coordination.
- Fleet operators and commercial drivers of electric trucks and buses — Clear guidance can reduce uncertainty about post‑crash protocols, insurance exposures, and expectations for tow/salvage, helping fleets plan training and operational responses.
- Caltrans and local transportation agencies — Best practices aimed at minimizing roadway closures and preventing structural damage to bridges could shorten disruptions and reduce costly detours and inspection costs.
- Communities near incident sites — Requirements to evaluate toxic emissions and set safety buffers aim to reduce public‑health exposure to airborne contaminants and firefighting runoff.
- Labor organizations representing drivers and first responders — Required consultation gives labor a formal seat at the table to influence safety procedures, PPE standards, and training expectations.
Who Bears the Cost
- Office of Emergency Services and state agencies (OSFM, CHP, Caltrans) — Agencies must invest staff time, technical expertise, and coordination resources to develop the plan and manage stakeholder processes without an appropriation in the bill.
- Local fire departments and emergency responders — Implementing the plan may require new training, equipment (battery‑suppression tools, monitoring gear), and operational changes that local budgets must absorb.
- Fleet operators and manufacturers — Manufacturers may face pressure to share proprietary battery data; fleets could incur costs for new response kits, training, and revised salvage/towing procedures.
- Taxpayers and state budget — If implementation leads to equipment purchases, statewide training programs, or new inspection regimes, those costs will fall on state and local budgets unless the legislature appropriates funds.
- Roadway owners and bridge managers — The plan’s emphasis on preventing structural damage and minimizing closures may require additional inspections or post‑incident remediation paid by Caltrans or local agencies.
Key Issues
The Core Tension
The central dilemma is balancing the need for robust, safety‑first response protocols (which may require resource‑intensive tactics, industrial disclosure, and extended closures) against pressures to conserve scarce emergency resources, protect proprietary manufacturer information, and reopen critical infrastructure quickly; the bill mandates planning but leaves the hard tradeoffs — and who pays for them — unresolved.
AB 855 sets a useful agenda but leaves critical implementation questions open. The statute prescribes topics for an action plan rather than operational standards, funding, or enforcement authority.
That means the plan’s real‑world impact will depend on (a) how OES translates broad topics into concrete procedures, (b) whether agencies and local jurisdictions adopt and resource those procedures, and (c) how manufacturers share technical battery information needed for safe response.
The bill’s text also contains drafting inconsistencies — alternating references to 'department' and 'office' and duplicated terms — and omits definitions (for example, what qualifies as an 'electric commercial motor vehicle'). Those drafting gaps can produce ambiguity about scope and lead to disputes over which agency leads coordination.
Other practical tensions include tradeoffs between conserving resources (water, aerial assets) and ensuring thorough extinguishment and monitoring, the tension between public‑health buffers and rapid traffic reopening, and the protection of proprietary manufacturer data versus responder safety needs. Finally, without earmarked funding, smaller jurisdictions and volunteer fire departments may struggle to implement any new recommendations, producing uneven geographic protection.
