Alabama has a few differences of note from federal laws. Firstly, Alabama allows longer trailers, they can go up to 57’. These longer trailers must still adhere to maximum distance of 41’ from the kingpin to center of tandems. Another difference is the availability for slightly higher weights for 6 axle semi trucks, at 84,000 lbs.
