Using a traffic script

I have a server that takes place in the 1970s and I want to use this mod to create immersion so you don’t see modern cars but I have no idea how to set it up. I tried to get it to work but I have had no luck. Any help would be nice.

\citizen\platform\levels\gta5 try in there

@GanjaMonster Thanks, I’ll try it.

EDIT: No luck
