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).
If there are more people aboard plus luggage or other equipment, this weight must be subtracted from the weight of the trailer. For instance: If a tow vehicle has a Combined Gross Vehicle Weight Rating of 9500 lbs. and the vehicle itself weighs 4000 lbs., a 5000 lb. trailer will sum up to 9000 lbs.
