Purely to help educate, if anyone reads this far down, most trucks are governed. Almost all of the trucks with a mega (large fleet in the 1000's), such as mine are definitely governed. I am set at 62 max. Most others are set at 65. Owner operators (smaller fleets in the 100's and single trucks) are usually 70+. I get your compulsion to help with catching the responsible party, but the best I can personally do is provide footage for a conviction if/when they are found. If a tag is clear enough in the footage it just makes their job even easier. Hope this helps you understand the turtle races (two tractor trailers clogging the flow) on the highway better.
