SB 121 Maryland Senate · 2025 Regular Session

Vehicle Laws - Noise Abatement Monitoring Systems Pilot Program - Inspection and Extension

SB 121 extends the pilot program for noise abatement monitoring systems in Montgomery and Prince George’s Counties through 2028, requiring counties to report detailed data on system usage, costs, revenue, and effectiveness. The bill modifies inspection rules to ensure recorded images from these systems (which detect excessive vehicle noise) are treated similarly to other traffic monitoring systems for public access. Counties must submit annual reports by December 1, 2027, covering warnings/citations issued, system deployment locations, performance metrics, and noise reduction outcomes. The program expires automatically on June 30, 2028, without further legislative action. This affects local governments operating the pilot systems and residents in areas where noise monitoring is deployed.
