How long do I need to keep an Ignition Interlock Device (IID) on my vehicle?

If you are required to have an Ignition Interlock Device (IID) installed on your vehicle, the IID must be maintained for six months from the reinstatement date. You must report to a certified IID vendor each month for maintenance to ensure the device is working properly.

In the case that you have a Limited Driving Privilege (LDP) and an IID installed, the IID must be maintained for the duration of the LDP.
