... and when you're done persecuting this guy make sure you remind him that he has been " Served and protected".
You can look at the HTA, as a traffic police officer you should be fairly conversant on the HTA, not just the little cheater Coles notes card, you will find there is no charge not having turn signals.
Actually the HTA dictates a white light facing forward, and a (one) red light facing rearward. That's it. No turn signals, brake lights or reflectors.
The best you could do is what we used to call a "Falstaff", a vehicle inspection by the MTO (we called it a Falstaff because that's where the inspection station was. I am old) where the operator is compelled to appear for an vehicle inspection by the ministry... that does not include turn signals. Ask me how I know.
You're talking about enforcing MTO regulations, which is not the purview of the constabulary.... but as you have noted you're gonna keep trying. Aren't ya?
If you're doing something incredibly stupid, then by serving you, they're protecting others.
You don't want blinding lights on your bike. No matter how bad your night vision is. It's hard enough to judge the distance and speed of a motorcycle. If you blind the person attempting it, they can't judge at all.
