This is especially true when it comes to the dearth of two-wheelers in the game. The Motorcycle Traffic Pack allows players to add a bunch of real-life brands into the game that makes for some great eye candy while players are stuck in traffic.

8Enhanced Vegetation

When creating a map as big asAmerican Truck Simulator’sneeds to be to provide a realistic trucking experience, some corners are going to have to be cut. In order to save on budget and development time, the assets for much of the game’s vegetation and a tad sub-par in places.

This is understandable, as players are going to be moving past them at high speeds, so they don’t need to be very detailed to look acceptable. It’s not likea farming simulator, where it needs to be perfect. That said, players who like everything to be perfect have taken it upon themselves to make the world look a bit prettier. It’s the perfect kind of mod, as it showcases the community doing a job the development team didn’t have the time for.

7Longer Yellow Lights

Those unfamiliar with driving trucks in the real world may fail to realize just how different from other vehicles they can be. One of the major differences is how slowly they pull off from a full stop, or the slow rate at which they decelerate. The consequences are that players pass a traffic light on yellow, but it turns red before they fully cross, leading to a fine.

To relieve some of this frustration, modders have extended the time for which lights remain yellow. Increasing it from 2 seconds to 4.5 seconds. This gives players a little extra leeway with traffic lights and will lead to a lot less unnecessary expenditure in the form of fines.

6Realistic Vehicle Lights

Much like the vegetation in the game, the lighting engine inAmerican Truck Simulatoris just as good as it needs to be. With so many other parts of the game requiring greater attention, it would be a waste of time and resources for the development team to create a top-of-the-line lighting engine.

The vehicle lights in the game are fit for purpose, but in certain situations, they can be hard to see properly. It makes for awkward times when the law requires a vehicle’s lights to be on in rain, even though they make no noticeable difference to visibility. This mod changes that, massively increasing the quality of vehicle lights, and improving overall visibility at night.

5Real Companies, Gas Stations & Billboards

For legal reasons, the developers ofAmerican Truck Simulatorcan’t use any real brands for most of their world. They pay for the licenses to real truck brands, as they are the most important part of the game, but for things like haulage companies, gas stations, and in-game adverts, they created fake companies instead.

However, fan-made content gets around this, as the developers aren’t liable for what the fans create. This means that those who want tohaul loads with real-world branding and supplies in themcan do so with the use of this mod, which changes all the logos on the game to be real-world ones.
