Download TruckersMP free app to play the multiplayer mode. This is an official tool created with help of the developers. It supports both ETS 2 and ATS. It uses its own servers that host thousands of players from all around the world. Visit "https://truckersmp.com/" and download the mod from the main page by clicking on the green button. You can also create an account in World of Trucks but this step isn't required.
The page wants you to register. This is an important step because you also have to log in with your Steam account to confirm the registration - this means that you need to own a legal copy of the game, have active Steam account and access to the Internet (one TruckersMP profile per one Steam account). Download the application, install it and run.
TruckersMP has an update system activates upon starting the modification. There is a possibility that your game may be up to date but the modification can be still in its older version.
In the upper left window of the app you can see the currently supported versions of the game. If the app isn't up to date then you will see the update button in the bottom right corner of the screen (it replaces the run button).
But what about a situation when the game received an update but the application is still in the older version? Go to the Properties (Library tab in Steam) and select "Betas" tab. There, you can choose non-standard versions of the game (older or beta).
Your account on the website is ready and you downloaded TruckersMP app. This means that you can now log in. Start the game by pressing "Launch" button (or "Install Available Updates" if there are new updates available).
Select a server on which you want to play. Choose your location (continent) to get a lowest possible ping (high ping may disconnect you from a server). Visit TruckersMP website to learn more about the servers. You can join a server only when its queue is shorter than 200 people.
After logging in you can choose your profile (you can use the same one for both multi and single player modes). You can join a server after fully loading the game and entering a truck - your position in a queue is presented in the upper left corner. You start in the place where you left your truck last time. However, you start with "Ghost Mode" that lasts a few seconds (other vehicles will go through you).
A few important things about your account:
- To run the game, you need to own a legal copy of the game and activated it on your Steam profile;
- You can only have one TruckersMP account per one Steam account (so avoid getting banned);
- You can run the game with your Steam account in Offline mode (however, you won't be able to see your friends, marked in green, in the game);
- TruckersMP doesn't work when you are using "Library Sharing" option in Steam;
- You can't join a server if you have other modifications than the original DLC and/or mods that are authorized by the administration (e.g. a mod that add snowing effect during winter).
