所謂的White-out就是這麼一回事。萬勿因為不是冰雨和大雪，駕車時就掉以輕心。這兩天南安省的天氣實在糟透，昨(24)日受到過百公里的暴烈猛風吹襲，接踵要來即時來個快速急凍的冷鋒 (Cold Front)，猛風仍未竭息下將降雪亂吹，令能見度大減，在大多倫多北面近巴里市 (Barrie)，惡劣的天氣就導致這宗嚴重交通意外。

現場在400公路近巴里市，界乎Mapleview至Innisfil Beach Road一段，由起初預計涉事約20至30部車輛，據CBC的報導，實際可能有近50至70部車輛連橫相撞，當中更有載油車，並出現漏油情況。

看到省警發言人帖文的片段，北部的現場仍然是刮著大風和下著雪，現場的能見度相當低，路面被大雪覆蓋，相信兩個元素加起來路面是相當難開。目前警方仍未確定肇事車輛的數字，幸而未有嚴重傷亡，只約10個人因輕傷被送到醫院檢查。

截至25日的中午時份，現場仍在清理中，省警安排了巴士接走出事車輛的司機和乘客，界乎以上提及兩個出口的400公路全面封閉。各位需要前往的朋友懇請格外留心交通及天氣情況。
