Dear Experts I was driving on F3 from Sydney to Newcastle, and a police patrol car was on the left side of the highway (not in the middle distributor normally the stop their sometime) and he was facing drivers from Sydney to Newcastle using patrol's camera I would assume. I was driving behind a truck, wasn't able to see what is in front of me. I tried to pass the truck and I was on 120 plus minus. I saw the cop (around 500 m), slammed on the break before approaching closer to him. He followed me and pulled me over and issued a ticket ( speeding fines). My question didn't he recorded my speed through his car's camera before I slammed the brake?? Or he guessed it? I should be on the same speed for about 3 seconds. Is this case arguable at court? Regards.
