Baltimore City - Speed Monitoring Systems - Interstate 83
HB 913 increases the maximum number of speed monitoring systems allowed on Interstate 83 in Baltimore City from two to four, making this authorization permanent. The bill amends Maryland’s transportation code (Section 21-809) to remove the previous 2026 expiration date and update the limit. It directly affects Baltimore City’s transportation authority, which would manage the placement of these systems on I-83. The key change is a straightforward increase in the permitted number of systems, with no additional requirements beyond existing local jurisdiction approval processes.

MODERATE
The bill was finalized as an enrolled version, adding formal signatures and proofreading details. Substantively, the bill now limits speed monitoring systems on Interstate 83 to a maximum of four total units, whereas the previous version allowed for a higher number. Additionally, a new operational rule was added to ensure that no more than one system operates in each direction simultaneously.
Scope change
The bill's scope was narrowed by adding a specific operational limit on the number of active speed cameras at any given time.
REQUIREMENT
The maximum number of speed monitoring systems allowed on Interstate 83 was changed from an unspecified higher number to a strict limit of four total systems.
A new operational constraint was added, prohibiting more than one speed monitoring system from operating in the same direction at the same time.
TIMELINE
The effective date for the repeal of the 2021 temporary act was updated from June 1, 2021, to June 1, 2025.
