To comply with BNSW rules and minimize chances of liability under the law we have to point out to participants the risks of cycling on our rides. There are the obvious ones, like collisions with cars and hitting pot holes etc, which can be covered by our standard Warning on the ride form. But we also need to mention any dangerous spots on the route, like a bad squeeze point, a tricky intersection or crossing, a narrow bit of road, poor shoulder, etc, that we should have identified beforehand. Muggacino’s Phil Johnstone has an article on this, which is a little complicated in his own detailed style, but worth reading. See http://www.muggaccinos.com/Liability/Provide_A_Risk_Warning.htm
