Law enforcement patrols will be increased through Labor Day weekend as part of a statewide effort to curb drunk driving. Extra patrols for the statewide "Over the Limit, Under Arrest" campaign are federally funded.

Nearly 50,000 Michigan motorists were arrested for drunk driving last year. Crashes involving alcohol are eight times more likely to be fatal than those not involving an impaired driver.

Those convicted of drunk driving face penalties including fines up to $500, up to 93 days in jail, up to 360 hours of community service, six points on their driver's license, driver responsibility fees of $2,000, higher insurance rates, and an automatic six-month license suspension.
