So not the most accurate means of measuring, but your average speed between the "yellow truck entrance sign" and "black & white centre lane only" sign was about ~92km/hr.
62.6m and it took you 2.44s, this has a lot of error because the distance was measured using Google Earth and a stop watch along with your video playing.
It wouldn't be outside of the realm of possibility your instantaneous speed at some point could've been 101km/hr. Your speed was definitely in excess of the posted limit.
1. They reduce speeds all the time, if he's using LIDAR then there shouldn't be any confusion; the speed would be displayed on the LIDAR device along with the distance it was measured from.
2. The location being 0.5km or 1km doesn't mean anything. Importantly, the Google Maps information would not be accepted in court. You may even need to get a ON Land Surveyor or road surveying documents from the City of Vaughan to show distances. This would not help you.
3. In your disclosure, does he write at what distance he got the speed of 101km/hr? Their LIDAR devices have a range of up to 9km.
You're going about fighting this the completely wrong way. You need to focus on the essential elements required to get a conviction for Speeding in Ontario: R. v. Vancrey, 2000 CanLII 26961 (ON CA)
1. Officer is qualified, received training in the use of the speed measuring device; he's also "current", which means some forces require that they're re-trained every year or 2 years... he has "currency" and is within the re-training period.
- if you choose trial, you can also question the officer about his training.
2. Officer tested the device as per the manufacturer's specification (before and after for radar, possibly only before for lidar); it's in good working order.
3. Officer stopped the correct vehicle
In order to fight speeding tickets, you generally go about fighting 1 & 2; making sure the officer tested it properly on the day the alleged offence took place. That he followed the manufacturer's specs and his training.
Request for the manual/testing-pages for the officer's speed measuring device.
You'll also have an opportunity to speak to the officer to clear up questions. If the crown has the essential elements to get a conviction; it's in your best interest to plea-bargain the best deal possible. In this case try to get something with no points.
It's difficult to fight speeding tickets in ON, because the essential elements to get a conviction are super easy to prove. In some instances, the officer isn't present at trial, or his notes are incomplete and in those cases you have a hope & prayer.
