Actually, the Topeka code only aplipes to any person residing in the city , so it wouldn't apply to visitors. Ordinances from the other cities I reviewed don't have that stipulation.The other curious thing about the laws is that they would appear to apply even to test-riding a bicycle, at a bike shop, for example. Weird.As to how cyclists are to know well, they have to check with their city and/or police. But yes, I would think a warning, rather than a ticket, would be appropriate in most cases.
