Attention speeders! Are you aware that on the roads there is these little white(also orange yellow or some other color) rectangle shaped signs with black letters and numbers on them?They look something like this.

Notice that there is some strange letters and numbers on it?What that sign means is, that this is fastest legal speed you can travel until further notice of another speed limit sign telling you different.About every tulsa road,street or highway has them.
These signs were not put there because the cops or the man wants to you suffer.These signs were put there for my safety,your safety and everyone else's safety.You speeding 10 or 15 miles above the speed limit puts everyone at a higher risk.The highway is not Nascar.
