Now, that being said, I did see the result of 110 mph once. It was an Aerodynamic Kenworth at the bottom of a 8 mile 8% grade. He topped the hill in 8th, popped it into 8 th over, burned his brakes to the ground, slipped it into Mexican Overdrive to save the engine and then drove past 3 runaway lanes before he could not negotiate a 40 mph corner. The trailer flipped over the guard rails which flipped the tractor on its side. That is what saved it from going over the same 500 ft cliff that the trailer went over. After sliding close to 700 ft on its side it came to rest in the middle of the road. He was from Ohio I think. He walked away from it, without a scratch. I don't think he came back.

You can speed limit the truck. Regardless of RPM and gear it will go XX mph. That's the most common. There is one that I refer to as a stairstep governor, that will teach drivers how to drive. Those that like to hit the RPM governor at each shift. For example 0-25 mph will only do 1300rpm, 25- 45 1600 RPM 45-XX Engine governor. If your truck speed limiter reads 127mph, guess what you can go as fast as you darn well please. 127 is known as no limiter. If it's anything but 127 your limited to that speed. There are may different parameters to set on these computers it's almost crazy. If you don't like your low idle speed, because your dash rattles, and mirrors bounce until you get a higher engine speed. That also can be changed to whatever you want. Hope this is a better understanding of how limiters are set.

I had a Truck Goverened at 72MPH and hated Hills. I was traveling through SC and going down Hills I let it roll so I could make it up the next with out dropping to a dangerous slow speed. Just past Spartanburg, Going down a Hill I noticed dust coming out of the Middle of the Interstate but still did not see any car. After I got to the top and back at the speed limit, A SC Trooper pulled along side of me and just looked up at me and then cut infront and got off the Interstate...

Some states say that anything over 15 on the posted limit in a commercial vehicle is attempted manslaughter. Keep THAT in mind. |
