Features:
- Draws blue tractor and orange trailer sweep path lines while reversing
- Fixed prediction distance of 5 meters
- Lines respond to steering, trailer angle, wheel contact, lift state, and steerable axles
- Automatically hides when the game is paused or the truck is not in reverse
- Calculates road grade from grounded tyre centres and suspension travel instead of chassis pitch or roll
- Single-axle trailers use the tractor's tyre fit only when their own layout cannot determine direction
- No cabin accessory required; the game's own trailer guide markers stay unchanged
- Does not capture the camera, mirrors, or depth buffer, and includes no ReShade or DX dll files
- Works with trucks and trailers only, not personal vehicles
- Includes exact Windows x64 profiles for several ATS versions with a telemetry-only fallback for unknown builds
Reverse Posture Assistant is a reversing aid built specifically for American Truck Simulator. It overlays predicted sweep paths for both the tractor and trailer directly in the game world, giving drivers a clearer sense of how their rig will move while backing up.
The overlay uses blue lines for the tractor and orange lines for the trailer, projecting a fixed 5-meter prediction distance. The paths dynamically adjust based on steering input, trailer angle, wheel contact, lift axle state, and steerable axle configuration. Road grade is calculated from grounded tyre positions and suspension travel rather than relying on chassis pitch or roll, so suspension height changes alone won't distort the guide on flat ground.
This tool is aimed at drivers who want a more precise visual reference during reversing maneuvers, especially with trailers, without needing any extra cabin accessories. It doesn't alter or interfere with the game's built-in trailer guide markers and avoids touching the camera, mirrors, or depth buffer systems.
