Ok, let me explain the details of the traffic ticket that I just received:

1) In Ontario, CA I was stopped at a railroad crossing, close to a
road intersection
2) Upon realizing that this wasn't the road line, I crossed the
railroad line, and stopped approximately 30 feet away, at the road
line
3) Police officer sees this, and pulls me over saying I "failed to
stop at the railroad line"

My assertion is that I committed no crime, and in research of the
California Vehicle code (section 22450a), a railroad line is not
treated the same as a road line in this respect (I had the right to
cross the railroad line granted no train was coming).

Basically I'm looking for the following evidence to contest the ticket:

1) Am I correct in asserting that I had a right to cross that line?
2) Is a railroad crossing treated as a road intersection in this respect?
3) Case evidence, if available to help support this.
4) Any other ammo to fight this ticket, as available would be appreciated :-)

I know you people aren't lawyers, all I need is some cursory legal
research please :-)
