Uploaded files up to 650 MB are scanned with VirusTotal automatically BEFORE the mod goes public. American Truck Simulator currently has 845 mods: 787 carry a finished clean verdict, and 58 file(s) exceed the 650 MB automatic scan limit (VirusTotal cannot scan those, and nobody checks them by hand). The result is shown on each card, and you can report any mod that looks wrong.
SCS games use .scs files, and load order matters. 1) Download the .scs file. 2) Copy it to Documents → American Truck Simulator → mod. 3) Enable it in the Mod Manager BEFORE loading your profile. 4) For maps, keep the map mod at the TOP of the list, add-ons below it.
They are free to download — there is no paywall on the American Truck Simulator catalogue and no sign-up required. A mod is only paid if its creator set a price, and that price is stated plainly on the card and the mod page.
Every American Truck Simulator mod card states the game version it was built for, and the sidebar lets you filter by version. After a game update, filter to the newest version first.
