Depends on the specs. Most major fleets will govern their trucks between 62 - 65 MPH, and the speed of some may be limited by electronic engine controls which limits how many RPMs the motor can turn. Some semi trucks out there are capable of running over 120 MPH, although they're typically governed, usually for insurance reasons, at a significantly lower speed. For example, Star ran trucks with a 500 horsepower Caterpillar diesel, 13 speed transmission, and 3.55 rear end gears - a combination which makes for a triple digit truck, but the fleet was governed at 65 MPH.
