Twenty-five people died in New York City traffic in December, and 4,277 were injured, according to the latest NYPD crash data report [PDF].

Based on monthly NYPD figures, 168 pedestrians and 10 cyclists were killed by city motorists in 2013, and 16,059 pedestrians and cyclists were injured. These numbers are preliminary, and official data from the state DMV won’t be available until later this year. In 2012, 135 pedestrians and 17 cyclists were killed by NYC drivers, according to the DMV, and 14,327 pedestrians and cyclists were injured.

Of 134 pedestrian and cyclist fatalities reported in 2013 by Streetsblog and other outlets, 19 were hit-and-run crashes in which the driver or drivers were not immediately caught or identified. Of the remaining 115 crashes, nine motorists were known to have been charged with homicide. In five of those cases, the driver was also charged with driving under the influence of alcohol or drugs. One crash resulted from a police chase. In two cases, the driver was accused of running over the victim intentionally. Only once in 2013 was a sober driver charged with homicide for killing a pedestrian or cyclist in a crash that did not involve a personal dispute or fleeing police.

Citywide, at least 17 pedestrians were fatally struck by drivers in December: two pedestrians in Manhattan; three pedestrians in the Bronx; five pedestrians in Brooklyn; six pedestrians in Queens; and one pedestrian in Staten Island. Among the victims were Gloria Mabry, Yunior Rodriguez, Siu Anthony Lee, Noshat Nahian, Marion Kurshuk, Enrique Clemente-Ovando, Vito Colella, Nicole Detweiler, and an unnamed male pedestrian in Brooklyn.

At least one child and two seniors were killed by motorists last month: Noshat Nohian, 8; Gloria Mabry, 74; and Marion Kurshuk, 78.

Across the city, 1,163 pedestrians and 175 cyclists were reported hurt in collisions with motor vehicles in December. Per NYPD policy, few of these crashes were investigated by trained officers.

Of nine fatal crashes reported last month by Streetsblog and other outlets, no motorists were known to have been charged for causing a death. Two drivers were unlicensed; three fled the scene and were not immediately caught or identified. Historically, nearly half of motorists who kill a New York City pedestrian or cyclist do not receive so much as a citation for careless driving.

Eight motorists died in the city in December; 1,394 motorists and 1,545 passengers were injured.

There were 17,260 motor vehicle crashes in the city last month, including 3,212 that resulted in injury or death. There were 203,390 total crashes in 2013, according to NYPD.
