Staff members, normally, have their in-game nicknames colored (except for orange color). GM’s, also, can hide their nickname and make it white-colored (as everyone’s is). Many GM’s would drive the Scout Extra_D, but with police painting on it.
You can find the list of Staff members here: https://truckersmp.com/team
Try turning off the "Load cabin accessories" and also "Load Flags" and check if it helps.
Also, just try to reinstall TruckersMP Launcher and install it to C drive, to get less problems.
How to reinstall TruckersMP Launcher:

Once you opened that folder, try to find the folder TruckersMP and delete it.
Open your documents and delete the folder(s) ETS2MP / ATSMP
Once you have done that, open your windows control panel and head over to programs and features. Once you are in there, delete the TruckersMP Launcher.
After that head over to our download page and download the Launcher.
Once the launcher is downloaded, run it as Administrator and follow the instructions.
