Question for our legal and LEO types...

The wife got a speeding ticket in the mail from Denver, 10mph over. I have heard that you don't have to pay any traffic fines for speeding unless you are personally served. Is that true? I read Colorado Revised Statutes 42-4-110.5 Part 2(a)(II) and I really can't decipher the language in the Statute. Does mailing it count as it being served?

The ticket says that if you don't pay it then a "Penalty Assessment Notice" will be personally served upon you with an additional fee of up to $59. I do see in the Statute it says they can't charge more than the actual usual costs of being served...

Secondly, in part (2)(d) it requires very specific requirements for posting a sign stating that they are clocking speed from one of these vans...I'd like to see Denver show proof that this sign was in place. I have seen these vans before and never seen a sign...

Should I press our luck and see if they actually serve her in 90 days out of my personal belief that traffic tickets should have to be given to you in person by a cop (<$99 dollars at risk) or should I just mail a check and be done with it ($40)?
