What this mod does

ATS AI Traffic No Default SCS Cars is a config mod by Kass, the author of Brutal Traffic, that removes all of the game’s stock cars from American Truck Simulator traffic. Those slots get filled by the cars from whatever traffic packs and vehicle mods you have installed.

What it’s for

Even if you install realistic car packs, the SCS models keep showing up and end up repeating. With this mod they stop spawning, so your modded cars appear more often and traffic feels more varied.

  • Removes all SCS cars from AI traffic.
  • Lets other car mods fill the roads.
  • It’s a lightweight mod: according to the author, it doesn’t affect performance and holds up during long sessions.
  • Compatible, according to the mod page, with most traffic car packs.

Version and requirements

Version 1.3, from September 18, 2026, is the one for ATS 1.61. It came out in March 2026 for 1.58, and the author has updated it with every game version since. It doesn’t require any DLC or other mods, and the page doesn’t specify a load order.

Before you install it

It only makes sense if you use a traffic car pack, since its whole job is to make room for one. Kass publishes separate versions for trucks and buses.
