Hazardous Materials: Request for Feedback on Hazmat Transportation Risks: Heavy-Duty Electric Vehicles Versus Internal Combustion Engine Motor Carriers
Published Date: 2/2/2026
Notice
Summary
The Department of Transportation wants your thoughts on how safe it is to haul hazardous materials using big electric trucks compared to traditional gas or diesel ones. They’re looking at how this switch might affect safety, emergency plans, and rules. If you’re involved in hazmat transport, speak up by May 4, 2026, to help shape future research and policies—this could impact costs and safety standards down the road!
Analyzed Economic Effects
5 provisions identified: 0 benefits, 1 costs, 4 mixed.
Responses May Guide Future Research
PHMSA may use the information it collects to develop a statement of work for further research into transporting hazardous materials in heavy-duty EVs and to identify potential regulatory adaptations. Stakeholders providing data and experience could influence the topics and scope of that future research.
Safety Topics: Batteries, Packaging, Charging
PHMSA explicitly seeks input on specific safety topics including lithium-ion battery hazards (thermal runaway, fire propagation), effects of EV battery weight distribution on cargo stability and packaging integrity, charging station vulnerabilities, and comparative fire characteristics of EV battery fires versus ICE fuel fires. Commenters are asked to identify hazards, testing needs, and standards gaps.
You’re Invited: Submit Feedback by May 4, 2026
PHMSA is asking industry stakeholders—like fleet operators, manufacturers, and emergency responders—to submit comments on hazmat transport risks for heavy-duty EVs versus ICE trucks by May 4, 2026. The notice explicitly says the Federal Government will not pay for any information or administrative costs; all costs of responding are borne by the respondent.
Request for Info on Emergency Response Needs
PHMSA asks whether emergency responders are adequately trained for EV-specific hazards (battery fires, toxic emissions, electric shock) and whether response tactics or vehicle badging should be changed for heavy-duty EVs carrying hazmat. The agency is seeking examples of current training and recommendations for additional responder guidance.
PHMSA Seeks Data on Economic Feasibility
PHMSA requests information comparing total operating costs, cargo capacity, range, route planning, and technological barriers between ICE motor carriers and heavy-duty EVs when transporting hazardous materials. The agency asked for suggestions on long-term economic studies to assess whether transitioning hazmat fleets to EVs is economically feasible.
