US EditionWashington, Idaho Report Relatively Low Hazmat Transit Incident Rates
Highway shipments of corrosives and flammables account for most cases, while Ohio’s damage total is driven by the East Palestine derailment, Trace One said.
- Trace One analysis of U.S. Department of Transportation data shows hazardous materials transit incidents surged 84.8% since 2010, reaching 27,355 annual cases in 2025, with California recording 11,462 incidents between April 1, 2021 and April 1, 2026.
- Highway transport accounted for 119,346 incidents from April 2021 to April 2026, far exceeding air and rail, while large industrial states like Texas reported 11,748 incidents driven by manufacturing and freight movement.

- Ohio's five-year damage total reached $920.8 million, nearly 30 times that of any other state, driven almost entirely by the February 2023 train derailment in East Palestine.
