    How are state speed limits determined?




    Whenever a new road is built in Texas, the entity constructing the roadway is required to reach out to the Texas Transportation Commission to determine the speed limit for the new road, according to the Texas Department of Transportation.


    LTW-2017-03-13-3Factors that determine a road’s speed limit include the road’s length and location, transitions from other speed limits, directional differences, trial runs of the roadway and the location of regulatory speed limit signs along the road, according to TxDOT.


    Local governments hold some control over determining speed limits as well. Cities, counties and other government officials work with TxDOT to conduct traffic and engineering studies and pass local speed ordinances, TxDOT Public Information Officer Deidrea George said.


    State Rep. Celia Israel, D-Austin, recently filed House Bill 1368 to lower the prima facie speed limits on urban district roads in Texas from 30 mph to 25 mph. The prima facie speed limit is the unspoken speed limit on roads with no posted limit.
