Smile. Your car is on candid camera in the District.

The grace period on 14 new speed cameras came to an end Friday. Instead of warnings, motorists who violate the speed limit will receive tickets in the mail.

The speed cameras are along stretches of Massachusetts and Georgia avenues NW, New York Avenue NE and Martin Luther King Jr. Avenue SE. An additional camera that detects trucks that enter a restricted area is in the 1800 block of Monroe Street NE and monitors westbound traffic.

Police said the cameras, which debuted May 20 and had a 30-day grace period, are in areas where speeding has been a problem.

The 15 new cameras, including the one to detect trucks, are part of a larger network of speeding cameras that already exist throughout the District.
