States With the Highest Posted Speed Limits
Statutory speed limits are established by state legislatures or city, county, or state transportation agencies. Posted statutory speed limits are enforceable by law and adapted to promote safe travel depending on the type of roadway. These statutory speed limits are typically 25 mph on residential roads, 55 mph on rural highways, and 70 mph on most interstate highways. But some states allow higher speeds.
