Starting October 1, all DUI/DWI offenders in Maryland, including those receiving probation, will be required to install an ignition interlock system under a new law aimed at closing a loophole in Noah’s Law, which previously allowed 60% of offenders to avoid this requirement. Montgomery County Police Officer Noah A. Leotta passed away in December 2015 after being struck by a drunk driver while performing a traffic stop on Rockville Pike. Leotta was working that night as part of the department’s Holiday Alcohol Task Force.
