Alcohol-Involved Crashes
In 2013, there were 723 drivers in alcohol-involved crashes; 513 (71.0%) of those drivers were coded as had-been-drinking by the officer on the crash form.
256 (49.9%) of the 513 drivers had a blood alcohol concentration (BAC) of 0.08 g/dL (grams per deciliter) or greater, and 131 (51.2%) of the 256 drivers had a BAC at or above 0.17 g/dL.
420 (81.9%) of the 513 drivers were coded as had-been-drinking and were tested for alcohol consumption.
Notes: BAC measured in grams (g) per deciliter (dL). BAC may not be reported if drivers are not tested or if the results are not available immediately (as in the case of a blood test). A driver may be coded by the officer as drinking even though no test is administered.
