IMPAIRED DRIVING IN RHODE ISLAND

Incidence of Impaired Driving

For one of every 110 miles driven in Rhode Island in 1999, a person with a blood alcohol concentration (BAC) >.08 sat behind the wheel. Police in Rhode Island reported 5,110 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 10,270 crashes in Rhode Island involved alcohol which killed 88 and injured an estimated 2,500 people.
