This exact same situation occurred with me.
I was driving in Huntsville going to Algonquin and on a slope. The weather was a bit drizzly and cloudy. On a slope, I must have been only a little over 100 in a 100 zone. As soon as the slope ended, I saw a cop car and I started to slow down. I noticed my speedometer and I was around 120kph. I started to slow down further as my car was full of camping equipment, I could not slam the brakes.
The cop came behind me and I pulled over. He said, I was going 148 kph! I was utterly shocked, as I noticed my speedometer after the slope to be at 120 kph. Something didn't seem right but I cannot argue with an officer. I accepted the ticket and now I am not sure what should I do?
He checked my records and told me I have a good record so he gave me a reduced ticket of 129 kph in a 100 zone and told me 2 demerit points. I checked online, it is actually 3 demerit points for 29 kph over. He also told me, if you opt to go to trial, we would fight it for 148 kph!
I am very disappointed as I usually do not speed. I love using cruise control and set it to 100-105 kph .
If I fight this ticket via X-copper or any other paralegal service, and lose my case, would I be convicted with 148 kph and 4 demerit points! It sounds and feels very unjust.
Any suggestions? Should I fight it?
