Attention, while this mod is complete, there is an alternative that I recommend using in conjunction with this mod, or on it's own. It's incredibly well made, and I use it on a daily basis.
Have you ever thought that the original Beamng crash sound was just bad, and the older mods replacing it sounded worse? Well this mod is for you! With a crash sound taken from a real crash test, it simulates an actual car crash sound, with revamped glass shattering.

You MUST press ctrl+L if the mod doesnt register. This reloads the lua and other things in the game. If this does not work quickly close and relaunch the game.
