Governor Cuomo recently signed into law legislation requiring passengers in motor vehicles over the age of 16 to buckle up in back. This is a change from the current law which requires them to wear seat belts only when in the frontseat. The new law takes effect November 1.
Note that in New York the driver of the vehicle is responsible for ensuring that his or her passengers are all wearing seat belts. Buckle up in back or your driver gets the ticket.
Why the new law? Studies have more conclusively proven that you are much less likely to suffer serious injuries or death if you wear a seat belt, even in the backseat. In fact, studies show that the use of a backseat seat belt could reduce death rates by 2/3.
