Japan is witnessing a sharp rise in driver’s license suspensions linked to drunk cycling, signaling stricter enforcement of traffic safety rules. According to the National Police Agency, 896 people nationwide lost their licenses for riding bicycles under the influence between January and September. Last year, only two people faced the same consequence.
The surge follows revisions to the Road Traffic Law implemented in November 2024. The law established punishments for cycling at or above a blood alcohol level of 0.15 milligrams per liter of breath. Authorities stated that intoxicated cyclists are now treated as potentially dangerous when driving a car, leading to tougher penalties.
Local public safety commissions impose license suspensions based on penalty points, a measure previously used for serious traffic violations or drug-related offenses. Since the law change, officials nationwide have increasingly targeted drunk cyclists. This action emphasizes public safety and accountability.
Data shows notable regional differences. Osaka topped the list with 340 suspensions, followed by Tokyo with 124, Wakayama with 73, and Nara with 66. In contrast, 22 prefectures recorded no suspensions, reflecting variations in local police practices.
Some local governments are introducing stricter measures. For example, Chiba prefecture dismisses civil servants caught riding or driving under the influence. Penalties for drunk cycling include up to three years in prison or fines of ¥500,000. People riding on the back of an intoxicated cyclist or providing alcohol are also subject to enforcement.
Police are increasing patrols as year-end parties approach, anticipating higher drinking rates. A senior NPA official said, “Drunk cycling can lead to serious accidents. Losing your driver’s license can affect your life and career. Everyone must follow the rule: don’t drink and ride.”
Authorities stress that drunk cycling penalties aim to protect public safety, reduce accidents, and promote responsible behavior. Consistent enforcement across all prefectures remains a key factor for success.
