Transportation - Study on Speed Limits - Interstate 495 and Connected Highways
Summary
SB 559 requires the Maryland Department of Transportation to conduct a one-year study on speed limits at highways in the State that connect to Interstate 495 (the Capital Beltway). The study must identify the affected highways and their current speed limits, and then examine five years of data on congestion, speeding tickets, crashes, and other hazards or incidents at those connection points. It must also assess whether it is feasible to require speed limits to change by only 5 miles per hour at these locations, and, if so, recommend measures to implement that approach.
The bill does not itself change any speed limits or traffic laws immediately. Instead, it creates a temporary reporting requirement directing MDOT to consult with local officials and stakeholders with traffic-safety expertise and submit findings and recommendations to the Governor and General Assembly by December 31, 2025. The act takes effect July 1, 2025, and automatically expires June 30, 2026.
Impact
SB 559 would temporarily add a study mandate to Maryland transportation law, specifically directing the Department of Transportation to evaluate speed-limit transitions on highways connecting to I-495. It affects MDOT’s planning and reporting duties rather than imposing a substantive change to posted speed limits, enforcement rules, or driver penalties. Any future policy changes would depend on the study’s findings and subsequent legislative action.
Sentiment
The available record suggests the bill is exploratory and policy-oriented, with no recorded committee debate or votes in the provided materials. Its tone is generally neutral and technical, focused on gathering data about traffic safety and speed-limit consistency around the Beltway. Because there are no transcripts or vote results, there is no documented opposition or support in the supplied context beyond the bill’s introduction by Senator Benson.
Contention
The main potential point of contention is the proposal to standardize speed-limit changes to only 5 miles per hour at highway connections to I-495, which could raise questions about traffic engineering, safety, and whether such a rule is practical across different roadway designs. Stakeholders likely to care include MDOT, local governments, traffic-safety advocates, commuters, and law enforcement, especially regarding congestion, crash patterns, and speeding enforcement. However, no explicit objections or endorsements are included in the provided materials.
