Make ATS Look More Realistic
Mod: Realistic Graphics v4.0
Improving the visual fidelity of a game like American Truck Simulator can go a long way toward reigniting your love for the game.
After all, who wouldn’t like a bit more eye candy to stare at while on the road for hours at a time?
With the Realistic Graphics mod, you’ll skyboxes, terrain textures, and weather effects are all upscaled to look more realistic and detailed.
Improve Vegetation
Mod: Enhanced Vegetation v3.2
Building off the previous mod, Enhanced Vegetation is one of the finest options for players looking to enhance ATS’ visual presentation.
The main focus of this mod is to replace vegetation textures throughout the game’s map to appear more sharpened and saturated.
Additionally, trees receive new color adjustments and textures that make them stand out even at higher speed limits.
Add More Realistic Rain
Mod: Realistic Rain v3.4
What good is all that lush vegetation if you don’t have equally-impressive looking rain?
With the Realistic Rain mod, damp weather in ATS takes on a whole new life with enhanced raindrop texture, color, transparency, and sounds.
These benefits extend to your cabin’s interior with an increased number of raindrops appearing on the windshield and windows.
Improve Vehicle Lights
Mod: Realistic Vehicle Lights v7.1.1
To help you more easily navigate those wet and slippery roads, consider installing the Realistic Vehicle Lights mod.
As its title suggests, this mod focuses on improving the details of vehicle lights while increasing visibility at long distances.
It affects not on the player’s vehicles but also AI-controlled vehicles and various other light sources throughout the game.
Add More Realistic Roads
Mod: Realistic Roads v3.2
Anyone who’s driven in real life knows just how rare it can be to find a smoothly paved road lacking any bumps, cracks, or jagged lines.
To bring that sense of realism to ATS, we suggest using a mod like Realistic Roads, which replaces road textures and makes modifications to road lines.
This includes fresh and dirty asphalt, pavement, and gravel roads with minor imperfections based on tire tracks and traffic flow.
Increase Yellow Light Duration
Mod: Longer Yellow Lights
We’ve all been there before: you’re approaching a light, it switches from green to yellow, and you cruise on through believing you’re clear.
Only instead, you receive a fine for driving past a red light due to your heavy load not making it through in time.
With the Longer Yellow Lights mod, this annoyance becomes a thing of the past as the yellow light phase of traffic signals is increased from 2 seconds to 4.5 seconds.
Add Real Companies
Mod: Real Companies, Gas Stations u0026amp; Billboards
From a legal perspective, it makes sense for the ATS developers to not include any real-life brands in the game other than the officially-licensed vehicles you drive.
However, with a mod like Real Companies, Gas Stations & Billboards, you can get a more authentic and genuine experience by adding well-known companies to the game.
Once installed, renowned brands will start to appear on warehouses and truck trailers throughout the enormous map alongside real-life gas stations as well.
Add Novelty License Plates
Mod: License Plates – Accessory Pack
If you’re looking to add some visual pizzazz to your favorite big rig, the License Plate – Accessory Pack mod is a great place to start.
It adds an array of high-resolution license plates based on all 50 states with a few novelty ones thrown in for good measure.
The plates can be connected to common accessory slots like bumpers, headache racks, bull bars, and anywhere else a plate would normally appear.
Customize Your Steering Wheel
Mod: Customize Your Steering Wheel: Choose The Parts
Along with modifying your license plate, why not add a mod that lets you customize your steering wheel as well?
With the Customize Your Steering Wheel mod, you’ll gain the option to change various aspects of your wheel including the color and parts of each section.
The mod comes included with a few pre-configured wheel designs that will spice up your rig with minimal effort.
Add New AI Vehicles

As a standalone mod, every car in this pack is compatible with all maps in the game, ensuring you see more vehicle diversity anywhere you go.
Drive AI Vehicles
Mod: Driveable AI
In alignment with the latest modification, the Driveable AI modification will allow you to occupy the driver’s seat of a limited number of NPC-operated vehicles.
As of this writing, it supports about 15 cars in the game, including various Ford and Dodge models in addition to police vehicles, and fire and garbage trucks.
The best part is most vehicles can still be tuned to your liking and feature functioning lights and sirens as well as custom interiors and engine sounds.
Add New Trailers

However, for the purposes of this list, we’re highlighting the aptly named Black Beauty 359, which adds a stylish-looking custom black skin with white accents for the Outlaw Peterbilt 359.
Considering this is one of the most popular vehicles in the game, you’ll want to make sure to personalize yours the first chance you get.
Drive a Transformers Truck
Mod: More Than Meets The Eye, Decepticon Truck and Trailer Skin
Instead of making ATS more realistic, what if you went in the opposite direction with a cool and creative skin based on the hit cartoon and film franchise Transformers?
With the More Than Meets The Eye and Decepticon Truck and Trailer Skin mods, you can give your Peterbilt an entirely fresh look.
The only choice left to make is whether you consider yourself a heroic Autobot or a villainous Decepticon.
Add New Wheels and Tires
Mod: Smarty’s Wheel Pack
While vanilla ATS may offer a decent number of options for customizing your trucks’ wheels and tires, there’s always room for improvement with a mod like Smarty’s Wheel Pack.
So, if you’re the kind of player who’s fixated on adjusting your vehicle’s performance, a mod like Smarty’s Wheel Pack will be useful.
It adds a variety of new wheels and tires that perform differently depending on the weather and road conditions.
Carry Heavy Cargo
Mod: Heavy Cargo Pack
If you’re looking to put your hauling skills to the supreme test, look no further than the Heavy Cargo Pack mod.

Improve the UI
Mod: SiSL’s FlatUI
For those who aren’t quite satisfied with the vanilla ATS user interface, SiSL’s FlatUI is an absolute game-changer.
Swapping out the default gradients and menu icons with flat colors and simpler symbols, this mod gives a more modern, streamlined look to the game’s UI.
Note that it’s still a work in progress, so you may encounter the occasional bug when navigating certain menus.
Connect All Regions
Mod: Coast to Coast Map
This next mod is for players craving a more seamless trucking experience without having to load into new areas.
With the Coast to Coast Map mod, you can drive to any part of the map in real-time using long inter-connected highways to get from one destination to the next.
However, to utilize it you’ll need to have the New Mexico, Oregon, Washington, Utah, Idaho, and Colorado DLC expansions already installed.
