「子どもや高齢者も車道走れって？」自転車の“青切符”何が違反？　おんぶ紐、子どもとの二人乗り、右側をちょっと走るのは？　弁護士が解説〈4月1日より道交法改正〉（集英社オンライン） - Yahoo!ニュース

This page explains the introduction of the "blue ticket" system for bicycle traffic violations starting April 1st through a lawyer's commentary. Applied to cyclists aged 16 and older, serious violations like drunk driving remain red tickets, while speeding, signal violations, riding without lights, and phone use while riding are subject to blue tickets. Sidewalk riding is permitted only when road cycling is dangerous, such as when parked cars obstruct the bike lane, but pedestrians have priority on sidewalks. The public has expressed concerns about the new system on social media.
