Hi, I have a couple of questions regarding Australia's mandatory bicycle helmet laws. 1). Can police fine someone just for sitting on a bicycle without a helmet? I was threatened by police with a helmet fine, just for sitting on my stationary bicycle without a helmet on my head. I was sitting on my bike reading a flyer in a shop window and wasn't moving. My helmet was in my backpack. A patrol car pulled up and rolled down the window and yelled out to me to put my helmet on. I refused. The two officers got out and threatened to write me a ticket. I said "Go ahead, let's take it to court and see what the magistrate says". After a bit more banter, they issued me a stern warning and left. 2). Is there an occasion where one's own safety trumps traffic law? I live in the country. I recently went on a long bike ride (70kms). I wore a helmet for the first half of the trip (morning), but as the day heated up I was starting to feel the effects of the sun on my helmet. I was very worried about my head overheating and suffering heat stroke, but I still had to get home. I soaked a T-shirt in water and wrapped it around my head like a bandana. This had the desired cooling effect and I was able to ride home very comfortably and safely. I wasn't concerned about police and the helmet law, I was more concerned for my own well-being. Thank you!
