Baltimore, Maryland –  LifeSafer® ignition interlock has been the go-to provider for drivers looking to get back on the road safely and legally after a DWI/DUI/OWI.  Currently, Maryland is one of 41 states that has implemented ALR (Administrative License Revocation) which means that your license will be confiscated immediately if your BrAC (BrAC Breath Alcohol Concentration) is above .08 OR if you refuse a BrAC test. Your license will either be suspended or revoked at that point, even though you have not been officially convicted in a criminal trial. Have no fear, LifeSafer’s ignition interlock service centers help drivers recover their license after a DWI/DUI/OWI

What is an Ignition Interlock?

Interlocks can vary in a few ways and the ignition interlock you receive depends on the legal requirements set by the state you live in and the specifics of your DWI/DUI/OWI. In simplest terms, an interlock is a car breathalyzer that prevents a user from starting a vehicle until a breath alcohol test is taken.  An ignition interlock device (IID) is the most common term for devices sometimes referred to as “in-car breathalyzer” or “car interlock” or “blow and go.” Your interlock may come equipped with or without a camera, as well as real-time reporting or other additional features. If the IID registers the breath test results over the preset limit, the vehicle will not start.
