Just curious, does the legislation specifically state that your helmet must be worn on your head? Or does it simply state that a helmet must be worn? On a long ride a few years ago it got extremely hot so I slung mu helmet over my shoulder on a long srtrap. the organizers at a rest stop saw it and said i must wear the helmet on my head. I showed them the waiver and also showed them that it only stated that I promised to wear a helmet but there was no mention of wear I had to wear the helmet. Perhaps your local legislation has a similar loophole?
