To amend title 23, United States Code, and the Infrastructure Investment and Jobs Act with respect to vehicle roadside accidents, and for other purposes.

HR 9536 updates highway safety rules to better protect people involved in roadside vehicle incidents. It expands definitions to explicitly include "occupants and pedestrians associated with disabled vehicles" in safety programs and data reporting. The bill mandates a new working group - comprising diverse stakeholders like first responders, truckers, and community advocates - to collect and analyze data on "Disabled Roadside Vehicle Crashes" and develop solutions. It also requires adding "roadside deaths" to injury health data reporting under the Infrastructure Investment and Jobs Act. These changes directly affect drivers, passengers, pedestrians, and emergency personnel responding to roadside accidents.
