For the first time in five years, deaths on New Jersey roadways increased.

In 2011, 82 more people died in vehicle-related accidents than in 2010. A total of 638 people lost their lives in 596 crashes last year. State police are expected to release why they think the number of fatalities increased in the coming weeks.

Half of the deaths are believed to be contributed to recklessness, especially speeding in residential areas. Township police have decided to enforce a “zero tolerance” policy for speeders in neighborhoods, which puts pedestrians as well as other motorists at risk.

The number pedestrian and bicyclist deaths have also increased. Police urge people on the street to be alert, wear reflective gear, do not walk around intoxicated, and to lower their music when listening to their personal music players.
