國外如何實踐這 維也納道路公約 CONVENTION ON ROAD TRAFFIC 允讓 ARTICLE 11 Overtaking and movement of traffic in lines 10. A driver who perceives that a driver following him wishes to overtake him shall, except in the case provided for in Article 16, paragraph 1 (b) of this Convention, keep close to the edge of the carriageway appropriate to the direction of traffic and refrain from accelerating.If,owing to the narrowness, profile or condition of the carriageway, taken in conjunction with the density of oncoming traffic, a vehicle which is slow or bulky or is required to observe a speed limit cannot be easily and safely overtaken, the driver of such vehicle shall slow down and if necessary pull in to the side as soon as possible in order to allow vehicles following him to overtake. 這是 義大利通往奧地利的 A22 Autostrade 當有後車超車時,是原本行駛在車道中央的前車,減速靠邊,前車允讓靠邊, 靠邊靠到什麼程度? 是右車輪完全壓在路面邊線上,完全偏到車道的右邊, 讓出車道左邊很大的空間。 當前車壓線時,後車就知道前車允讓了 隧道內可以超車, 隧道內也壓在路面邊線上 這台露營車的右車輪完全壓在邊線上 貨櫃車右輪貼在邊線上, 允讓超車 行車靠右,讓出車道左邊的空間, 當超車的這台車回到原車道時, 轉向空間更大,對兩車都更為安全 當前車的前方有"內側車道"和"中線車道"二條車道, 可以選擇 (1)而前車選擇靠右, 行駛在"中線車道",沒有擠進"內側車道", 代表前車已經"靠邊",表示"允讓" (2)如果前車正在”內側車道”超越,前車或亮右方向燈表示允讓,表示前車已經準備讓出內車道, 準備駛入原行路線, 表示允讓了。
