It's over the limit NO. By definition, the speed limit is the fastest you can legally drive.Additional information:Technically speaking, the speed limit signs in every state mean what they say. 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.
There is a stretch of Texas state route 130 north of San Antonio with a posted speed limit of 85 mph (137 kph).
