Transportation Article §21-810 of the Maryland Annotated Code, effective October 1, 2009, authorizes the Maryland Department of Transportation State Highway Administration (MDOT SHA), Maryland Transportation Authority (MDTA) and Maryland State Police (MSP) to use automated speed enforcement (ASE) technology in work zones. For additional details of the law authorizing the use of automated speed enforcement systems in highway work zones, refer to Transportation Article §21-810 of the Maryland Annotated Code.

Highlights of the law include:

• Speed cameras may be placed in work zones along expressways and controlled access roadways with a posted speed limit of 45 mph or more.
• A citation may only be issued if the vehicle is exceeding the posted work zone speed limit by 12 mph or more.
• Conspicuous signs must be posted to give drivers adequate notice of the cameras.
• The District Court has set the amount of the civil fine at $40
• Revenue is used to cover the costs incurred by MSP and MDOT SHA in implementing and administering the automated speed enforcement program. The balance of any excess revenues is distributed to MSP to purchase replacement vehicles and related motor vehicle equipment used to outfit police vehicles, as outlined in Maryland Annotated Code Article §12-118".
