"Don't Block the Box" is back, part of an effort to reduce traffic congestion around New York City.

Called "Clear Intersections," the program will have block-the-box violations "aggressively enforced" at 50 key crossings in the five boroughs, the mayor's office said in a statement Monday.

The NYPD will hire an additional 50 cops to deal with intersection violations. Violators face minimum fines of $115 and points on their license.
