Today, as I was heading eastbound on Broadway, I saw an officer on a motorcycle on the other side of Broadway(on the side of westbound traffic). As i saw him I quickly looked at my speedometer and started dropping my speed, but apparently it was too late and he had clocked me in at 42 mph, in a 30 mph zone. I was sort of zoned out and didn't pay attention to what speed I was going, and I knew I was over the speed limit as soon as I looked at my speedometer. This is my first ticket, and I have the option of going to traffic school, after which I would have no points on my drivers record. Would that be the wise thing to do rather than fighting the ticket, on the bases that he was on the other side of the street and his radar couldn't have clocked my car accurately due to westbound traffic ?I didn't see the speed limit sign until several yards ahead of the location where he pulled me over, the increment between that speed limit sign and the one before was about a mile. On the ticket that was given in the field "Laser/radar #" there is no number it's just blank so does that mean he didn't put the number of his radar gun on purpose/forgot or didn't use a radar gun at all and just said he clocked me in at 42?
