ABSTRACT - Aim To analyze the severity of automotive injuries associated with blood alcohol concentration (BAC) in increments of 0.01%. Design/setting Epidemiological study using the Fatality Analysis Reporting System. Participants All people in US fatal automotive accidents, 1994–2008 (n = 1 495 667). Measurements The ratio of serious: nonserious
injuries for drivers, by BAC.

Findings Accident severity increases significantly even when the driver is merely
‘buzzed’, a finding that persists after standardization for various confounding factors.
