Impaired Driving

Incidence of Impaired Driving

For one of every 150 miles driven in Vermont in 1999, a person with a blood alcohol concentration (BAC)>.08 sat behind the wheel. Police in Vermont reported 353 crashes involving a driver or pedestrian with a BAC of .01 or more. Formulas developed by NHTSA were used to estimate the number of alcohol-related crashes where alcohol involvement was not reported by the police. An estimated total of 2,620 crashes in Vermont involved alcohol which killed 34 and injured an estimated 940 people.

  • Positive BACs below .08 were involved in an estimated 80 crashes that killed 6 and injured 100
