Reverse Posture Assistant

The Reverse Posture Assistant draws the predicted sweep path of your tractor and trailer directly into the American Truck Simulator world while reversing. Blue lines mark the tractor boundaries, while orange lines mark the trailer boundaries. The prediction distance is fixed at 5 m and dynamically responds to steering input, trailer angle, wheel contact, lift axle state, and steerable axles. Features: World-space guide lines appear in reverse gear and are hidden when the game is paused or when leaving reverse gear. Road grade is calculated from grounded tyre centres and per-wheel suspension travel, rather than relying on chassis pitch alone — so changing suspension height on level ground won't tilt the guide. No cabin accessory is required, and the game's original trailer guide markers remain unchanged. The mod doesn't capture the camera, mirror images, or depth buffer, and includes no ReShade or external DLL hooks.
