Michigan has a .08 blood-alcohol content (BAC) drunk driving law. 

A first-time offender convicted of drunk driving faces:

• Up to 93 days in jail
• Up to a $500 fine
• Up to 360 hours of community service
• Up to 6 points on a driver license
• Up to 180 days with a suspended license with a restricted possible after 30 days

Convicted drunk drivers are also subject to an additional $1,000 penalty that will be imposed for two consecutive years.

According to the National Highway Traffic Safety Administration, laboratory and on-road research shows that the vast majority of drivers are significantly impaired at .08 with regard to critical driving tasks such as braking, steering, lane changing, judgment and divided attention.

In addition to the change in the drunk driving standard, the law also contains a zero tolerance for drivers with certain illegal drugs in their system. These "schedule 1" drugs are those with no medicinal use, such as marijuana, GHB, cocaine and cocaine-derivative drugs. Prosecutors do not have to prove the driver was impaired just that they were driving with those drugs in their system. The same penalties for drunk driving will apply to those convicted under the zero-tolerance drug provisions.

Under implied consent, anyone that refuses a breath test the first time is given a one-year driver’s license suspension.
