curious, if I was driving 100km/h and a car passed me doing 130, and a cop pulled me over saying I was doing 130, do the radars know the difference of the two cars? what if cop met the two travelling cars? just a hypothetical question

Re: Radar
The radar will give a reading for the faster vehicle and the officer's eyes will tell him or her which vehicle is moving faster.

Former Ontario Police Officer. Advice will become less relevant as the time goes by !
Re: Radar
There are different modes of operation for most radar devices. Typically, they return the strongest reading. So if you had a small motorcycle overtaking a large truck, the radar would likely show the speed of the truck, even though it's slower. Some radars also have a "fast" mode, where they can be set to show the highest speed. So in the above example, in fast mode they'd ignore the stronger signal from the truck and instead show the weaker (but faster) reading from the motorcycle. Some radars also have directional modes, so that they only show the speeds of traffic heading towards or away from the radar gun. In your example, if both vehicles were side by side and of the same size, I'd argue the radar could pick up either vehicle unless in "fast" mode. If not, it would be up to the radar operator to visually determine which of the two vehicles was travelling faster.

Hand-held device placed securely in motor vehicle
Hi everyone. I'm asking for a friend who has a question of interpretation.
He was ticketed for using a hand-held device. He contends that he was acting within the exemption provided under Subsection 14 (1) of O. Reg. 366/09, which reads as follows (emphasis added):

People are Driving Faster
Hey guys i just wanted to know what speeds you see others do on the roads on a regular basis. As we all know no body drives 100 km. It seems they only hit that speed twice once on the way up and once on the way down.
it seems the De Facto limit on the 401 is about 120-130. But lately i dont know if…
136km/h in a 100km/hr, possible win?
On June 10, 2017, I was pulled over by an OPP on the 403 heading WB and told I registered 136km/hr. I kept chit chat to a minimum and took my ticket and went on with my day. I later requested my disclosure and did not receive it until a week before my Oct. 27 court date, and so I had my date…
Ontario reintroducing Photo Radar/Speed Cameras?
Anyone know any more information? Apparently kathleen wynne mentioned trying to introduce legislation after more than 20 years of no speed cameras. My guess is that it wont happen, since they've tried before many times to bring it back after it was abolished.
Slowest of multiple targets, ticketed anyway....
The other day I was given a ticket for speeding 119 in a 90, on highway 17 near Marathon, ON (Speeding ticket capital of the universe, BTW). The officer claims to have "clocked" me using the vehicle mounted radar at 121 KMH and dropped it (presumably to lower fine and demerits).
I was not going that…

going 50 over the limit
If the speed limit is 50, and you do 100+, not only do you get 6 points. Your car gets impounded for a week, and your license suspended for 7 days, along with a hefty fine of at least $2000. The penalty is actually the same as for racing. The law came in effect on October 1, 2007. Remember -…
