FREDERICK, Md. (AP) Two new speed cameras are monitoring traffic in Frederick.
City police say the devices were activated Friday in the 1400 block of North East Street.
They bring to six the number of speed cameras installed in the city since late May.
All the cameras are within a half-mile of a school zone. Police say the program is designed to slow traffic near schools.
The devices automatically issue $40 tickets to the registered owners of vehicles going at least 12 mph over the speed limit.
At least one camera has been vandalized. Police Chief Kim Dine says those who damage the cameras are only hurting public safety and costing taxpayers money.
