City of Frederick - Noise Abatement Monitoring Systems - Authorization

HB 617 authorizes the City of Frederick to use noise monitoring systems to enforce existing motor vehicle noise limits. The bill allows Frederick to deploy up to three fixed or mobile systems that automatically capture images of vehicles exceeding noise thresholds (by at least 5 decibels), along with decibel readings and license plate details. Before use, the city must post locations online and install visible signage, and vehicle owners can request reviews of issued notices. This directly affects drivers whose vehicles exceed noise limits in Frederick, with enforcement handled through the city’s designated official. The bill amends Maryland’s vehicle code to add these specific monitoring procedures for Frederick.
