Interlock Devices, One’s Driver’s License, and the State

Different states have varying DUI processes.  Depending on the severity of the offense, offenders may have a different set of requirements than an offender with a similar conviction in a different state. Depending on a particular state, the process one must go through following a drunk driving (DUI) conviction varies. In some cases, an offender may be required to install an ignition interlock device. “An ignition interlock device or breath alcohol ignition interlock device is a breathalyzer for an individual’s vehicle. It requires the driver to blow into a mouthpiece on the device before starting or continuing to operate the vehicle.” (1)


In order to discover what is required of an offender in a particular state, it is essential to look at a particular state’s laws.  DUI laws vary according to state, county and city. In order to find out if an ignition interlock device is required, an offender receives a court order or letter containing final offense information.  This will also contain assigned requirements specifying if an ignition interlock device is required.  Interlock devices are often required to fulfill these requirements in the case of a suspended or restricted license after a DUI offense.

An offender’s monitoring authority and/or DUI attorney will also be able to help in understanding the time period and exact steps one must complete in order to regain a driver’s license.

Some states may require various paperwork in order to purchase an ignition interlock device. Paperwork may include a court order, vehicle information and/or monitoring authority involvement.
