In American Truck Simulator, Long Combination Vehicles (LCV), or simply Doubles, are configurations of trailers requiring two or more trailers to be added to the truck to lengthen the size of the load and challenge the driver's skills. These types of trailers were announced on May 5, 2017, and were added in update 1.28.
There are five available configurations in American Truck Simulator:
|Rocky Mountain Double||2||2|
The table below shows all the accessible states in American Truck Simulator, where LCV is allowed or not, and what trailers can be taken in. If you fail to obey the restriction, you will get an Illegal Trailer ticket at a weigh station.
|State||STAA Double||Rocky Mountain
There are exceptions to the restrictions above, such as a road briefly passing through a restricted state where you won't get ticketed, or a road running through a National Park where all commercial trucking is prohibited.
