If you are receive three (3) or more convictions for driving while your license is suspended or revoked within a seven (7) year period then you will be considered a repeat offender under Michigan’s Repeat Offender laws.

If you are arrested as a repeat offender, the law enforcement officer will destroy the metal license plate of the vehicle you are driving, whether you own the vehicle or not. A temporary paper license plate will be issued allowing the vehicle to be legally driven. A new metal license plate cannot be issued until your case is resolved in court.

Sanctions under the Repeat Offender laws include additional driver’s license suspensions or revocations, metal license plate confiscation, vehicle immobilization or forfeiture, registration denial, the use of ignition interlock devices, and mandatory substance abuse treatment. Repeat offenders who cause an accident resulting in a long-term injury or death are charged with a felony and face thousands of dollars in fines and years in jail in addition to other penalties.

When drivers lose driving privileges after being convicted of a third drunken driving violation, or receive a fourth additional suspension because they drove while their licenses were suspended or revoked, these repeat offenders are subject to registration denial.

Registration denial includes any vehicles that are registered, co-registered, leased, or co-leased by the repeat offender. During registration denial, it is a crime to attempt to purchase, lease, or obtain a vehicle. Unless a circuit court order is requested and issued, a repeat offender may not transfer a vehicle to any family member if that vehicle is carrying a temporary plate, is immobilized, forfeited, or subject to registration denial. Registration denial continues until the repeat offender is eligible to reapply for a driver’s license.

As you can tell the penalties for driving with a suspended license can be harsh and continue to go up if a person is convicted of the violation subsequent times. If you become a "repeat offender" in the eyes of Michigan law then penalties can be quite severe.
