Vanilla ETS 1 looks washed out and sounds tame. These mods fix that:

Given the age of the software and the difficulty in finding safe, functional mods for ETS1, it is recommended that users consider the following alternatives:

| Feature | ETS1 Free Mods | ETS2 Free Mods |
|---------|----------------|----------------|
| Availability | Declining, archived | Active on Steam WS |
| Map size | Small expansions | Whole continents (ProMods) |
| Modding tools | Manual text edits | Official Blender Tools |
| Safety | High risk of dead links | Steam curation helps |

Driving the same Mercedes Actros or Volvo FH12 gets old. Free truck mods add licensed models with custom interiors and sounds.
