I ran no front plate for years, but recently got pulled over for it. I think they target people without front plates here, then try to find anything else they did wrong in one stop. He said I was speeding (45 in a 40), and when I looked in my glovebox I saw my proof of insurance printout was expired, which I knew I had renewed, but I have a few cars so sometimes I forget the latest paperwork in one. Luckily I don't have tinted windows but I'm sure he would've given me something for that, too.
Anyway, the whole stop cost me just about $100 in fix it tickets, but the insurance thing could've been much higher ($700) if I couldn't prove it, PLUS I had to make three trips to the police station at different hours to get them all signed off. Finally I mailed in some remaining form.
Overall, it was a miserable experience, trying to visit the police station and sign it off, trying to find a cop to approve my freshly-installed front plate, and the lingering deadlines and potential fines over my head. The stress and time spent was not worth the "cool" look of no front plate. From now on, I think it's not worth it. Maybe if I had a Porsche or Ferrari or something...
