Q: 71-mph in a 45-mph zone. There is no information on the citation regarding any speed timing device that was used to calculate my speed.

A:  You can always fight a traffic ticket. The issue is whether it is worth the time, effort and money balanced against your chance of winning. A lawyer would need to know more facts to give a thorough opinion, so I suggest you consult with one. My question is, if you were only cited with failure to obey a traffic control device, (red light, yield sign, whatever) which carries no points or license suspension and a small fine, why would you fight it? If you truly believe you are innocent, have a good driving record and some sort of plausible defense, plead not guilty, go to the hearing and tell your side of the story to the judge.
