Incidence of Impaired Driving
For one of every 80 miles driven in New Hampshire in 2000, a person with a blood alcohol concentration (BAC) >.08 sat behind the wheel. Police in New Hampshire reported 1,480 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 7,120 crashes in New Hampshire involved alcohol which killed 49 and injured an estimated 1,460 people.
