We examine the effect on the incidence of casualties and crashes of a city-wide vehicle speed limit reduction in New York City (NYC) streets. The law change, part of Mayor Bill de Blasio’s Vision Zero Action Plan to improve traffic safety, cuts the default speed limit for streets with no speed limit signs from 30 to 25 mph beginning November 7, 2014. We use a monthly panel dataset with crash statistics for the entire population of NYC streets, from July 2012 through March 2019. Several difference-in-differences regressions show a statistically significant and meaningful decline in injuries and crashes.
