Fourteen new speed cameras — and a camera to detect trucks driving in a restricted area — debuted Tuesday in the District.

The speed cameras are in areas where speeding has been a problem, D.C. police said, including stretches of Massachusetts and Georgia avenues NW, New York Avenue NE and Martin Luther King Jr. Avenue SE. The camera to track trucks that enter a restricted area is in the 1800 block of Monroe Street NE and monitors westbound traffic.

Violators will get warning citations during a 30-day period, police said. After the warning period ends, police will issue tickets.

The cameras join scores of others in the D.C. area. The locations of the 14 new speed cameras, and the direction in which traffic is monitored, are as follows:
