What is an ignition interlock device?

This is a device the courts requires to be placed on probationers’ vehicles if they’re placed on probation for DUI offenses. It is literally installed in the vehicle, and the probationer will have to give a sample of their breath before the vehicle will actually start. It is required for a certain period of probation. There is a cost that the probationer will have to pay for its installation, and it is court-ordered requirement.
