Explanation
When you change lanes, you need to check for safety in every direction: front, rear, left and right (Rules of the Road (kyōsoku), Ch. 5, Sec. 5, 2(1)). With a bicycle right beside you on the left, you need to be prepared for it to change course suddenly. When you pass on the right of a bicycle, leave enough space, or else drive at a safe speed for the space you have (Road Traffic Act, Art. 18, para. 3).
