I don't know if I put this in the right category, but I likely did.
I haven't went on Truckers MP for one reason; I don't have any actual trucks.
Here are my "trucks":
Skoda Superb (Steam Workshop), black, police blue singular light
Renault Master (Modded), Police Nationale skin (Steam Workshop), 2 blue small lights (blue color modded), multiple Renault Master customizations
Hey, I like the police vehicles, ok?
Not only that, but apparently, using vehicles that look like police vehicles isn't allowed unless you're a moderator or something.
So, my best guess is that this question's a waste of time, and I need to save up for an actual, legitimate truck, right?
