The semi-truck without the trailer weighs around 20,000 lbs. An empty trailer weighs around 12,000 lbs, but it depends on what type of trailer it is. There are hundreds of different configurations. The point is...the maximum legal weight that an 18-wheeler can weigh is 40 tons (80,000 lbs).
Since most trailers of this type weigh about 100lbs per foot of deck length (16' trailers will weigh about 1,600lbs, 18' trailers weigh about 1,800lbs and 20' trailers weigh about 2,000lbs), you must deduct that trailer weight off of the GVWR to find out what a trailer can truly carry on top of its own bed.
