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.
