Here's what you should of done, and can use this in the future: Officer: after he has your DL, INS, and reg... (For example u were going 70 in a 55 zone) You: "Officer, I'm not sure what the speed limit was?" Cop: "The posted speed is 55 MPH" You: "Ohhh, I thought it was 65, that's why I was going 5 over" Cop: "Alrighty, but still I'm going to have to cite you" You: "since I wasnt sure of the posted speed limit is there any way you could write me a ticket for driver inattention?" OR The cop might just write u for that w/o even asking. Driver inattention might cost u about $15 more for the fine BUT.....is a NO POINTS violation. OR In your case....fight it in court and argue u thought the speed was 65 MPH and weren't "paying attention" Judge might drop it to "driver inattention" end result, no points, no insurance increase.
