NEW YORK, NY September 10, 2008 —Don't block that box. At noon today, the city made it much easier to ticket drivers who clog up intersections.

REPORTER: Earlier only police officers could hand out the $115 tickets, but over the summer the governor signed a law allowing all traffic enforcement agents to write the summons as well. Mayor Bloomberg says the new measure will reduce traffic congestion.

BLOOMBERG: You cannot block the box. If you can't get into the intersection, stop before you get there. I know it's annoying, but you're just going to create a much bigger traffic jam for everyone else, including yourself.

REPORTER: The NYPD ticketed 14 thousand drivers for blocking the box last year - the city says that figure's likely to go up sharply.
