The transmission on a semi truck has more gears than a car and a lower top speed; the low gear is around 2 MPH and the highest may be 64 MPH on one of the 16 speeds. If the driver is going down a hill sometimes they can drive over the top speed of the transmission by shifting to neutral and letting gravity do the work, which is called Kentucky Overdrive.
