Statewide Speed Limits
According to Tennessee Code Annotated 55-8-152, the following maximum speed limits apply in Tennessee, with individual counties and municipalities setting lower speeds on individual roads as needed:
- Interstates and limited access freeways (urban and rural): 70 MPH
- Divided highways: 65 MPH
- Undivided and two-lane roads: 55 MPH
- Residential streets: 30 MPH
Note that speed limits along a particular stretch of road may be lower than these limits, but will never be higher.
Resources by County or Municipality
In cases where the following data sources are used to set speed limits, it MUST be confirmed either with the street view reticle in WME or reports from "on the ground" that no speed limit is posted on the road segment. If in doubt, do not set or verify the speed.
