Sharing the Roadの無料動画を見ましょう

You may not know this, but if a cyclist can't see around a corner or over a hill on a road, they are allowed to take the lane to keep a driver from passing. Passing in that situation is extremely dangerous, as you can see here. Please be patient, and only pass when you can see what's coming the other way.
