On a two-axle truck, what is the forward distance?

兩軸卡車的前向距離如何定義？

AForward distance for a rigid vehicle is the distance from the rear axis to the front of the vehicle or its load, whichever is foremost (including collapsible mirrors).剛性車輛的前向距離，是從後軸基準線到車輛或貨物最前端的距離，以更靠前者為準，並計入可折疊後視鏡。BForward distance for a rigid vehicle is the distance from the rear axis to the front of the vehicle or its load, whichever is foremost (excluding collapsible mirrors).剛性車輛的前向距離，是從後軸基準線到車輛或貨物最前端的距離，以更靠前者為準，但不計可折疊後視鏡。
