The most common probationary measure used by the MVA to guarantee that drivers do not become repeat offenders is the use of the Interlock Ignition System. An ignition interlock system is a device that attaches to your car which tests your BAC before allowing you to start the engine.

This system is used as the court sees fit to stop Maryland DUI offenders from operating their vehicles while intoxicated, but is generally set well below the legal limit so that even one drink will not allow the car to be used. Ignition Interlock systems are expensive, and can be placed on your car for up to three years. In addition to being a safety device, they are also a very embarrassing reminder of the importance of remaining sober while driving. An Ignition Interlock system will certainly be visible to any passengers in the car.

Like the other penalties for Maryland DUI/DWI infractions, it is a punishment that you may be able to avoid with an expert defense attorney by your side.
