When approaching the weight station on a loaded truck, the PrePass light bulb (a) lights up in red, and instead of a squeak a pleasant (hopefully) female voice will sound. In the green light left a squeak by default. No video, sorry.
P.S. If you do not like the sound – change at your discretion, the file is open for editing.
Test: 1.33.
Installation: Move the downloaded file to: Documents / American Truck Simulator 2 / mod and connect to the mod-manager.
Great idea, Can you create one for pre-warning of say 10miles before there is road avent or detour. Sometimes I find I am barreling down the highway, next second you are on top of it and theres not much you can do about it. Now that would be great asset.
