After the 30-day warning period, drivers caught going 12 mph or over the speed limit will receive a $40 ticket.
The city of Hagerstown installed its first speed-enforcement camera on Tuesday.
The camera is installed on Northern Avenue at Crofton Road near the Fountaindale Elementary School.
A 30 day warning period began on Tuesday, said Police Capt. Mark Holtzman. After thirty days, anyone driving 12 miles or more over the 25 mph speed limit will receive a fine of $40.
The cameras will be in effect Monday through Friday from 6 a.m. to 8 p.m.
Officials are expected to install more cameras in three to five additional areas in upcoming weeks.
