Rollover crash

From CarAccidentLawyers.wiki, a sourced reference on car accidents and law firms

A rollover crash in this table is a fatal traffic crash recorded as involving a rollover in the FARS auxiliary accident file, with its fatalities summed as people rather than vehicles. The Fatality Analysis Reporting System manual defines the vehicle event as rotation of 90 degrees or more around a true longitudinal or lateral axis, and says it can occur at any time during the crash. The national figures cover all selected fatal traffic crashes, so they are not limited to passenger-vehicle car accidents or to people traveling in the vehicle that rolled over.[1][2][3]

Official definition and data selection

The rollover crash selection uses the crash-level involvement category, while the manual describes rollover or overturn as an event experienced by an individual vehicle during the crash sequence. The vehicle-level rollover field is derived from the sequence of events beginning in 2022, according to the manual, which identifies the rollover event in that sequence rather than a separate death measure. The rollover crash table therefore counts the deaths recorded for selected accident records and does not count the number of rotations, the number of overturned vehicles or only their occupants.[1][2][3]

National figures

For 2020, the national rollover crash selection recorded 9,051 deaths, while traffic crashes overall accounted for 39,007 deaths across the United States, with the selected category included in the overall total.

Limits of the term and figures

A rollover crash death count includes everyone killed in a selected event, so it does not establish that each person died inside the vehicle that experienced the rollover or overturn. The involvement category is not a finding of responsibility for a car accident, and these national fatal-crash figures provide no estimate of rollovers with no qualifying fatal injury. The rollover crash category can overlap other recorded circumstances in the same event, so its fatalities should not be added to other involvement categories as if they were mutually exclusive groups.[1][2][3]
