TAIPEI (Taiwan News) — Taiwan reported an increase in violations involving riding under the influence for cyclists and operators of slow-moving vehicles, prompting warnings of stricter enforcement.

The National Police Administration reported 12,095 violations involving slow-moving vehicles in 2025, up from 7,337 a year earlier, representing a 65% annual increase. The number of cases involving refusal to undergo breathalyzer tests reached 4,046 last year, a 39.9% increase from 2,746 in 2024, per CNA.

Under the Road Traffic Management and Penalty Act, bicycles such as YouBikes, electric-assisted vehicles with a top speed of 25 kph or less, electric scooters, and skateboards are categorized as slow-moving vehicles.

Police said efforts to curb drunk driving among automobile drivers have shown results over the past five years, according to CNA. However, violations among slow-moving vehicles have bucked this trend. Police noted that some intoxicated individuals opt for bikes due to a perceived lower risk of punishment.

Officers monitor riders for erratic behavior such as swerving or drifting out of bike lanes or roads. If alcohol use is suspected, police may stop the rider and administer a breathalyzer test.

Cyclists found with a blood alcohol concentration exceeding 0.15 milligrams per liter face fines ranging from NT$1,200 (US$38) to NT$2,400 and are prohibited from continuing to ride. Vehicles may also be confiscated. Those who refuse a breathalyzer test can be fined NT$4,800, per CNA.

If the vehicle involved has auxiliary power, such as a pedal-assist electric bicycle, riders may also face charges under the Criminal Code for offenses against public safety, which carry more severe penalties.

Police said that since August 2024, all police agencies have been required to conduct special enforcement operations targeting drunk driving during peak hours and in key areas, including near restaurants, KTVs, nightlife districts, and major roads.

Data on traffic accidents or injuries caused by intoxicated cyclists was not provided.
