Re: Two Tickets
Based on what you posted, the 21460(a) will be difficult to beat... As for the 22350, your only saving grace would be if the 30mph speed limit is not justified by a valid Engineering and Traffic Survey (read CVC 40802 which I linked above).
You should contact CalTrans and request a copy of the most recent survey that was conducted for that stretch of road... When you get it, post it here and we'll go from there.
I am right 97% of the time... Who cares about the other 4%!
