LA ignition interlock manufacturers have installation sites in counties throughout the state.

The State of Louisiana requires the installation of an ignition interlock device (IID), sometimes referred to as an in-car breathalyzer or breathalyzer interlock, as a condition of reinstatement of driving privileges for DWI/DUI offenders. The device must be installed in all vehicles the driver will be operating, not just the vehicles the driver owns.

An IID requires the driver to submit a breath sample into a breathalyzer device attached to the car’s ignition. If the breathalyzer detects a blood alcohol content (BAC) above a preset level the vehicle will not start. Further, the IID will require “rolling retests” during the operation of the vehicle to prevent attempts to bypass the breath test device.

The driver must pay for the cost of installation, which is generally around $125, and the monthly calibration and maintenance fees, which cost about $65 a month. Prices for IID installation, calibration and maintenance may vary from one provider to the next.

A driver seeking reinstatement must select an ignition interlock provider from those approved by the Louisiana Office of Motor Vehicles. The list below provides the names and contact information, as well as links for some providers. Contact these IID manufacturers for further information on installation facilities and prices.
