I just heard from the Calgary Herald that Bylaws is planning a pathway crackdown on "reckless speeding cyclists" from now until October. They'll be out there ticketing cyclists for speeding (no telling whether tickets will be issued for all speeds above 20 km/h, though in the past they've limited it to speeds above 25 km/h). I was also told they'll be looking for bells on bikes, since these are required equipment, and I got the impression they might also ticket for failure to ring your bell (though you can also ring a gong -- that's the exact wording -- or use your voice).
It goes without saying that there's a higher likelihood of speed measurement in the 10 km/h zones. On the other hand, while speed control is essential in some areas, it's absurd to ticket cyclists on remote, deserted pathway sections.
If you see a bylaw officer with a radar gun, let us know the location.
