Vision Zero: New York to Lower Speed Limits

"Mayor Bill de Blasio’s traffic safety push yielded perhaps its most significant change early on Friday, when the State Legislature approved a plan to reduce the default speed limit in New York City to 25 miles per hour," reports Matt Flegenheimer.

In addition to replacing speed limit signs all over the city, the new speed limit will also require traffic engineers to adjusting the timing of traffic signals.

"The city will have some time. The reduction from 30 m.p.h. cannot begin until 90 days after Gov. Andrew M. Cuomo signs the bill into law. (A spokesman said Mr. Cuomo was expected to do so.)"
