After the success of European Truck Simulator (ETS) and then by it's sequel European Truck Simulator 2 (ETS2) the team from SCS Software from the Czech republic have released a parallel version for the Americas aka American Truck Simulator (ATS)

 

You can find the game on Steam http://store.steampowered.com/app/270880/ and the official website http://www.americantrucksimulator.com/ as it's still in it's infancy so far only California and Nevada but I'm sure more states will come, like the evolution that happened with ETS2, screenshot below;
