The law required the issuance of warnings during the 30-day period after the first work zone automated speed enforcement (ASE) system was in place. To meet this requirement, warnings were issued for a 45-day period (October 1 through November 15, 2009) after the first Maryland SafeZones ASE system was in place, exceeding the 30-day requirement.
While not required by the law, from the start of the long-term contract in 2010 through November 2023, Maryland SafeZones also issued warnings for a three (3) week period at the start of enforcement at new long-term work zone deployments. Once the program was well established statewide, the extra three (3) week warning periods were discontinued. Warnings may still be issued, on occasion, at the discretion of the Maryland SafeZones program.
