This paper compares estimates of the proportion of driver fatalities in which the driver is legally intoxicated from two data sources, accident reports and toxicological reports of blood alcohol concentration (BAC). A total of 1, 260 driver fatalities in Texas had BAC test results available for study. Of the legally intoxicated driver fatalities identified by BAC tests, 68 percent of the corresponding accident reports did not show alcohol as a contributing factor in the accident.
