No matter what kind of sticker you put on your vehicle, you’re bound to antagonize some portion of the population, so I have never put a sticker of any kind on my pickup truck.
However, several years ago I put a Disabled Veteran license plate on my pickup truck and immediately noticed a change in traffic around me. Vehicles will now come and tailgate me inches from my bumper and blow their horn if they think I’m not driving fast enough, and there are those who will now cut me off in traffic. This never happened before I put the DV plate on my truck, and I think they’re probably doing it just because they assume I won’t chase them down and kick their asses now that they see I’m disabled.
Surprising how accurate that statement is. The only thing on my car is my CIB (Combat Infantry Badge) front license plate. It has the depiction of a musket on it. I picked up my grandkids for my daughter at school and was asked by a teacher directing parking lot traffic to not drive onto school property with anything depicting a 'gasp' gun. I suggested she educate herself on what that symbol might possibly be and no, I would not be removing that plate for no one.
