Wow, to head south? Or towards Highway 5? I saw alerts that cars with <3 people had to get on the highway before 7am, and it didn’t specify which highway… I just assumed it was Hwy 5, as per usual.
A few years ago coming back from Hualien they had this going on. I pulled up by myself and the guy looked at me, didn’t ask if I could speak Mandarin, then just yelled to the guys a little further up in Taiwanese, “something, something, adoga.” They just waved me on. Apparently couldn’t be bothered trying to explain it to me.
