This will need to be kept in the car or cars for a period between 6 months and a year following the end of the license suspension period. In addition, repeat offenders will also need to have ignition interlock devices installed in their automobiles. In these cases, they will need to maintain the devices in their automobiles for a period between one to three years.
If you are convicted of a DUI offense in the state of New Jersey, you will be required to hand over your license to the court. Unlike many other states, you will not be eligible for a temporary license that allows you to drive for certain permitted purposes.
