The speed limit is 50; the speed limit is 80. Realistically speaking Texas appears to have a fairly liberable ticketing policy, and being a primarily rural state, some of the interstate speed limits are 75 and 80. The Texas Dept. of Transportation's website says: Speed limits are posted primarily to inform motorists of the speed considered reasonable by a majority of drivers on a particular roadway. Motorists, especially those unfamiliar with the road, can use this information to evaluate how they should drive on a particular road. A safer driving environment is established when motorists drive at the same speed.There seem to be more warnings than tickets given out in Texas. See the reference below for more information.
