Safe speeds

Speed management to prevent serious injuries and fatalities

Keeping people safe on Massachusetts roadways is Massachusetts Department of Transportation's priority. One life lost or altered by a serious injury on any roadway is unacceptable. In Massachusetts and across the US, the speed that people drive can make a big difference on the safety of our roadways. Higher speed increases the risk of a fatal or serious crash and reduces the likelihood of survival. Every mph matters: each 1 mph increase that a person drives can be attributed to a 3% increase in potential loss of life. Safe vehicle speeds make streets better for everyone, whether you are traveling by car, wheelchair, bicycle, stroller, foot, or bus.

MassDOT is committed to helping realize safer speeds across the Commonwealth to prevent serious crashes. Our goal is zero fatalities and serious injuries. Learn more about speed management and resources to implement speed management in your community.
