The Silly Bay Bridge
This is quite an old thread so I'm very surprised nobody's posted anything different to the questionable "obey the city like a dog" responses I see here.
Here's some tips that might make your life (the working taxpayer yet guilty until proven innocent) easier:
Don't fight your ticket in court, the cops WANT you to do that because they get paid extra to show up. They couldn't wait for you to try to fight it in court- don't give them the satisfaction. Fight your ticket by mailing a written piece: Trial by Written Declaration.
23336 vc says you broke the posted speed limit. 22351 says, so what? as long as I didn't break 22350 which backs up that it was more than safe at that moment to do so. It's the bay bridge. How on earth can you do 70mph if everyone else is going 50mph? Simple, because there's either no traffic, or the car in front of you is going 70 also- thus, safe to do so.
As a second argument, use 40803(b) to question the speed survey done on the bay bridge, which has had a 50mph speed limit for quite some time. The fact is, many people are ticketed on the bay bridge for 70mph... which means many people do 70mph on the bay bridge at one point or another. It's tricky because when the bridge is clear, even 60mph seems too slow but when it's crowded, 10-30mph is possible, making 50mph sound like a reasonable average.
Yes, this is A GAME. It's unfortunate that many traffic regulations turned out that way but despite what cops tell you, what cops themselves are brainwashed into believing, this system is not for your safety. If it was, it'd be a LOT harder to get a license at DMV. This system is a racket, it's designed to take your money. That's why even if you fight your ticket by written declaration, you still have to pay the fine. If you win, they give you the rebate-- *cough* excuse me, the refund back.
So fight any and all tickets that you get, every single time. Even if you lose you most likely will get a reduced fine. It's pitiful for working taxpayers to be bullied by the city.
