成都一名驾驶员在200米的距离内被18辆车超越，交警查证后发现其在行驶过程中存在边开车边刷手机的行为1。龟速行驶已被认定为违法行为，不仅会显著降低道路通行效率，还容易诱发交通事故和路怒事件。据统计，车辆行驶速度每降低10千米/小时，道路通行能力就会下降约15%1；当速度差达到32千米/小时时，事故发生概率约提升16倍1。此外，团状拥堵区域的交通事故概率约是普通路段的3至5倍1，而由拥堵引发的路怒事件占比约为12%1。
为了有效治理这一现象，成都交警自2025年4月起上线了智慧系统，通过被超车次数和车速排名自动锁定违规车辆1。根据规定，高速公路最低车速不得低于每小时60公里1。这一举措旨在通过技术手段强化对龟速行驶的监管，确保道路安全畅通。
A Chengdu driver was overtaken by 18 vehicles within a 200-meter stretch while driving and using a mobile phone simultaneously 1. In response to such traffic violations, Chengdu traffic authorities launched an intelligent system starting in April 2025 designed to identify and penalize excessively slow driving by automatically flagging vehicles based on the frequency they are passed and their speed rankings 1.
Driving at abnormally slow speeds constitutes a traffic violation with significant consequences for road efficiency and safety 1. According to traffic data, for every 10 kilometers per hour reduction in vehicle speed, road capacity decreases by approximately 15 percent 1. When speed differentials reach 32 kilometers per hour between vehicles, the probability of accidents increases roughly sixteenfold 1. Additionally, traffic congestion caused by such violations creates accident-prone zones where accident probability is three to five times higher than on normal road sections 1. The regulatory standard on expressways mandates a minimum speed of 60 kilometers per hour 1, and approximately 12 percent of road rage incidents stem from traffic congestion 1.
