What is a DUI Ignition Interlock Device


What are DUI ignition interlock devices?
An ignition interlock device (IID) is a small breath test machine that is wired to your vehicle’s ignition and installed on your dashboard. Before your car will start, you first must breathe into the interlock device. If the interlock detects alcohol on your breath, your car will not start. Your local criminal court may require an ignition interlock device to be installed on any vehicle you plan to drive.

Your local Department of Motor Vehicles (DMV) or Department of Driver Services (DDS) has a list of approved top interlock companies in your area. You MUST use one of these state-approved interlock companies for installation and monitoring of your ignition interlock device.

Mandatory Interlock Situations
There can be several reasons why an ignition interlock device will be mandatory equipment on any vehicle you drive after your DUI arrest. You must have a state-approved interlock device installed:

  • Prior to being allowed to recover your vehicle from the impound lot
  • If required by your bail bond company as a condition of bail
  • Prior to receiving a restricted license or work permit that allows restricted driving privileges

For practical reasons, in some cases, you are allowed to drive if you can prove that you have contracted with an ignition interlock company to install your device.

Ignition Interlock Installation & Monitoring
You must make an appointment with a state-approved ignition interlock installer. You cannot install an interlock yourself, or have your regular mechanic install it. The interlock company will install two pieces of equipment: a small handheld device that you breathe into, and a small relay box that fits under your dash out of sight. The handheld device and the relay box are connected by a coiled cord. The installer will show you how to use the ignition interlock, and tell you how often you are required to come back in for monitoring.

Ignition Interlock Costs
You typically don’t pay for the ignition interlock device itself. Instead, you pay a monthly fee to the interlock company. This fee is regulated by the State and can vary across the country, but expect to pay around $65 -$95 per month. Do not damage or destroy the interlock device or you will have to pay for repairs or a new one. Obey the rules of the interlock program – you don’t need more legal trouble as your expert DUI attorney prepares to fight your DUI charges.
