How can a cop give a speeding ticket without radar?

Question

On my speeding ticket it says the officer's speed measurement device was pace. How can this hold up? Can I easily contest it?

Answer 1

<p>got pulled over for speeding in az. officer cited me for going 80+ in a 45. He also said that he had marked it civil instead of criminal. He did not use a radar because it is not marked. He did not pace me either. He was going East bound and I was going West bound and said I was racing. Can I fight this or just pay it?</p>

Answer 2

a cop gave me a ticket bases on pace, but he was in front of me and l was also keeping my distance, so how can he say l was going fast when l was driving behind him?
