Speed limit in Dumbo to be lowered to 20 mph as nabe becomes Brooklyn’s first ‘Regional Slow Zone’

The speed limit in a 0.18 square mile slice of Dumbo will drop to 20 mph as the nabe becomes Brooklyn’s first “Regional Slow Zone,” city officials announced Wednesday. 

The slowdown — a result of the passage of Sammy’s Law last year — is meant to increase traffic safety and decrease the severity of crashes, especially for pedestrians. In the last five years, the small Dumbo slow zone has seen 10 severe crash-related injuries and one death, according to the Department of Transportation.
