Safety guidelines for cycling in traffic Please post your safety tips for cycling/commuting that should help you get to your destination place in one piece.

I came across a nice printed guideline a few years ago when working as courier, it was posted on the wall in the base and covered many common road situations. Recently I tried to look it up on the web but with no luck, so I thought that placing a community wiki question here could be beneficial for many commuters.
A lot of cyclists promote vehicular cycling in which you act just like a car, obeying all of the rules of the road.  This includes respecting all stop signs &amp; lights, travelling in the same direction on the same side of the road as motorized traffic, and using the full lane (taking the lane), often ignoring marked bike lanes if they are too small or marginalized.

To me, vehicular cycling means acting like you belong on the road and that you have the legal right to be there (which you do).  I think a lot of bicycle accidents happen because the cyclist is trying to stay out of the way of cars and in doing so becomes very difficult for cars to see.
