I means Interstate. Some state has the maximum speed of 65mph but here in Michigan our maximum speed allowed is 70 mph which is equivalent to 112 kmh. BUT there is a big but people tend to go higher than that specially if they think and see that cops are no where to be found waiting for them speeders. They go as high as 75 or 80 mph!! That's why nobody would ever dare to cross this road or else, dead you!! LOL!
