While driving back to canada, I got speeding ticket 89mph in 65 mph zone in NY State - Chatham city on hwy I 90 ( Berkshire spur). I requested to the officer to show my speed in his redar. He rudely replied "I am not showing u anything". He was so rude and loud through out which in fact scared my kids. In supporting desposion document it says in item#7 charge base on officer's : direct observation. In item#8 it says speed verified by radar. There is no fine set in the ticket . I am not sure if I plea guilty or not. If I plea guilty, what would be the charges? I am a Canadian citizen so it would affect my insurance and point, right?
