MD SB292

Police officers must document all reasons for a traffic stop on any citation or police report resulting from the stop

Numerous traffic violations become secondary offenses only, meaning officers can only enforce them when a driver is already detained for another suspected violation; these include unregistered vehicles, improper registration plates, failure to signal, excessive noise, window tinting, equipment violations (headlamps, tail lamps, mirrors, stop lamps), and driving in bus lanes

Officers cannot stop vehicles for expired registration until the first day of the fourth month after the original expiration date

Evidence obtained during stops that violate the secondary enforcement requirements is inadmissible in any trial or proceeding

Officers who fail to comply with these provisions may face administrative disciplinary action; the bill takes effect October 1, 2025
