Twelve people died in New York City traffic in March, and 3,641 were injured, according to the latest NYPD crash data report [PDF].

As of the end of March, 24 pedestrians and cyclists were reported killed by city motorists this year, and 2,778 injured, compared to 33 deaths and 3,246 injuries for the same period in 2014. Those figures represent a 27 percent year-to-year reduction in fatalities, and a 14 percent drop in injuries.

Citywide, at least six pedestrians and were fatally struck by drivers: two in the Bronx; three in Brooklyn; and one in Queens. Among the victims were Dave Jones, Xiali Yue, Kadeem Brown, Tierre Clark, an unnamed female pedestrian in Queens, and an unnamed female pedestrian in Brooklyn. Motorists killed at least one child and two seniors in March: Tierre Clark, 5; and the unnamed pedestrians in Queens and Brooklyn, whose ages were reported as 80 and 84, respectively.

NYPD reported no cyclist deaths in March.

Across the city, 786 pedestrians and 159 cyclists were reported hurt in collisions with motor vehicles. Per NYPD policy, few of these crashes were investigated by trained officers.

Of six fatal crashes on surface streets reported by Streetsblog and other outlets, two motorists were known to have been charged for causing a death. The driver who hit Dave Jones, reportedly during a police chase, was charged with manslaughter, and the motorist who killed Xiali Yue was charged under the Right of Way Law. Bronx District Attorney Robert Johnson filed no charges against the driver who killed Tierre Clark and Kadeem Brown, who were on a sidewalk when they were struck. 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.

Three motorists and three passengers died in the city in March; 1,293 and 1,403 were injured, respectively.

There were 17.842 motor vehicle crashes in the city last month, including 2,687 that resulted in injury or death.
