No, this isn't commentary on the recent primary elections. It's about those times when a bicyclist shouldn't stay to the right of the lane. For example, pass to the left of a car that is preparing to turn right. The fellow in the white shirt and shoulder bag is in a very bad place:
I've had a couple of terrifying moments recently, when I saw cyclists squeeze by on the right side of cars that were turning right. This guy tried to share a lane that was too narrow, putting himself and other road users in a risky situation. Two blocks later, he zipped by on the right of a car as it started to make a turn into a parking garage. No one expects to be passed on the right when they are in the right lane signalling a turn. That includes bike-on-bike situations too - I've had people squeeze past me on the right as I was turning. Scary!
On the other hand, I have also seen motorists try to make a right turn from the left lane rather than merging (safely) into or behind bicycle traffic in the right lane. This is neither safe, legal, nor practical. After all, there is more traffic behind the cyclist that will have to be dealt with.
There doesn't seem to be total agreement about right turns in a wide right lane or next to a bicycle lane. Many people see the bicycle lane being similar to a crosswalk or sidewalk, meaning that motorist turn across it after yielding to any traffic in that lane. I tend to prefer that drivers merge into the lane so I can pass them on the left, where I know they won't cross my path. This is especially true if it is a wide shared lane without bike lane markings. But I see many drivers get confused by the presence of a cyclist, swinging to the left of the lane so I have room to pass on the right - that just means I have to merge over further in order to pass on the left instead. What do others prefer?
Please drive and ride safely!
