Road positioning when stopping at an intersection with stationary traffic When the light is red and there are cars in a line. Since bicycles ride on the very right do we go ahead to the stop light or stay behind the cars? I live in British Columbia, Canada.
I'm from BC, you have the option of taking the centre of the lane and waiting like a vehicle, or you can stay to the right if there is room (at least 1.5m or 5ft). If you stay to the right, basically you ride in an imaginary bike lane if there isn't one painted on the road, so you ride all the way up to the light on the right hand side of a line of cars at a red light. I do this pretty much every single day on my way home from work. Some intersections even have a button for cyclists to push, like the kind pedestrians push when they want to cross, but for cyclists waiting at the intersection. 



When you stop however, do not stop beside the car at the front to the line, you never want to be in a vehicles blind spot. Pull up just ahead of it and make eye contact with the driver so he knows you're there. If the first car in line is signalling to turn right, then stop just behind them and wait for them to turn in front of you before proceeding to the front of the line. 

Motorists are supposed to shoulder check when turning right at intersections to check for cyclists, but it's my experience that most motorists don't even know that bikes are allowed to ride on the road, so always drive defensively.
