Automated Speed Enforcement (ASE)

Subscribe to E-mail Alerts Subscribe to Email Alerts

The Maryland State Highway Administration (SHA) promotes a three-pronged approach to effectively managing speed related safety problems: Engineering, Education and Enforcement.

Automated Speed Enforcement (ASE) systems can be an effective tool for managing speed and reducing speed related crashes when used correctly and in the appropriate circumstances.Through an ASE program involving public education and visible enforcement, SHA seeks to change behavior and urge drivers to do what they already should be doing: driving responsibly, staying alert, and obeying the posted speed limit.

Maryland law, effective October 1, 2009, allows Automated Speed Enforcement in certain school zones and work zones.
