The 1968 Real-Time Traffic Info website flashed a "purple" alert, which meant the average speed was 20 kilometers The Directorate General of Highways said the congestion started at 10 a.m. and is expected to last until 6 p.m. Traffic jams frequently occur at the Yilan to Pinglin section.

The DGH highlighted nine stretches on national freeways where traffic jams frequently occur. For National Freeway 1's northbound lanes, they were the Xiluo to Puyan system, Nantun to Houli, and the Hsinchu system to Zhubei.

國道路況預報達人 張譽耀:「到九點為止國五北向的雪隧通過量,大約為1萬4千輛次,相較於去年109年中秋連假的同期大約增加了13%。」高公局公布,國道9大易塞車地雷路段,國一北向部份,西螺到埔鹽系統,南屯到后里,及新竹系統到竹北,下午三點後會開始湧現車潮,而國3北向部份,竹山到中興,霧峰系統到霧峰,大山到香山,關西到大溪路段,中午過後車多,國5北向部分,宜蘭到坪林,早上開始已湧現車潮,預估行車時間,是平常7倍。國道整體交通量,預估達114百萬車公里。至於東部交通,"蘇花改"20號晚間北返車潮,一直塞到晚上11點才紓解,預估21號北返車潮會變少,路況較為平穩。

公路總局第四區養工處副處長 林俊和:「(昨天)北返的車流量,我們統計出來的結果1萬7千5百多輛,今天早上(路況)順暢,(北返車潮)如果湧現出來的時候,會在蘇花改南端的路口那邊做節流點不會說(車潮)一下子擁擠進來。」
