Proposed Nashville ordinance would lower some residential speed limits below 30 mph (Vision Zero Watch)

A Metro Nashville ordinance introduced this week seeks to lower the speed limit in residential neighborhoods to at least 25 mph from the current 30 mph limit.

BL2019-1492 instructs the Metro Department of Public Works to complete the department’s analysis of the effectiveness of reducing speeds on neighborhood streets. The bill states speeding in residential areas “poses serious risks to public health and safety and is of significant concern to all citizens.”

The bill cites multiple studies on the topic, including findings by the Vision Zero Network which found 5 out of 10 pedestrians struck by a vehicle driven at 30 mph will survive. That rises drastically to 9 out 10 surviving if a vehicle is driven at 20 mph.
