Note: FARS records a driver as drinking when police reported alcohol involvement or a test of the driver was positive for alcohol. It is not NHTSA's alcohol-impaired measure, which uses a blood alcohol concentration of .08 g/dL or higher. One crash can be in two or more rows. NHTSA's definitions

Note that alcohol data is often missing. For that reason, this data element may under-count the actual number of drinking drivers.
