It is not $10 anymore. 2 years ago I got a fix it ticket for no front plate(on my car of course), and it was either pay a fine of $170, or fix it, get it signed off, and pay $35. And that was 2 years ago, so I'm sure it's even higher now, as they jack up the penalties in a mad dash for revenue.
That's a total BS ticket too. I wouldn't even recognize it as legit. I'd crumple it up, throw it away, and the state could go F itself. Wanna arrest me for it? Come and get me then. I'd turn it into a greedy lawyers' wet dream, and turn it into a media circus. 300ft? Why would you need to see someone's signal from that far away?
Give the CHP office a call, and talk to someone high up the ladder. Be nice about it, but let them know that the ticket seems kind of unnecessary, and they just might throw it out. Worth a try at least!
