20 is Plenty
for Salt Lake City.
We’re calling on the Salt Lake City Council to prioritize safety by adopting a default 20 mph speed limit on most city streets. Add your voice.
The risk of death or serious injury increases significantly with higher vehicle speeds.
— AAA Foundation for Traffic Safety, 2011.
The Research is Clear.
This is not a new concept. When cities make 20 mph the default speed limit, they make streets safer and communities stronger.
Fewer Deaths.
When implemented on a wide scale without traffic calming, 20 mph speed limits reduce casualties by 22%.
Lower Speeds.
Portland State University researchers found a significant decrease in vehicles traveling faster than 30 mph after adoption.

Safer Streets.
“It is well-established that higher motor vehicle speeds result in more serious outcomes for the vulnerable road user, and the severity of an injury exponentially increases with speeds.”
— Brian C. Tefft, 2013, AAA Foundation for Traffic Safety
Stronger City.
The World Health Organization recommends 20 mph limits as best practice in residential areas.
— W.H.O., 2017, ‘Managing Speed’
We Have the Power.
It’s a simple change.
“On all streets and at all places, the prima facie speed limit shall be twenty-five (25) miles per hour, except as otherwise provided in subsection A of this section, or in such other streets or places as otherwise posted or marked as directed by the city transportation engineer.” — Salt Lake City Ordinance 12.36.020.B — Speed Limits
