Does anyone know for sure if there is a current official mandate on self-quarantine if one enters Bangkok from another province? I’ve only seen rumors so far, but so far have seen no official accounts as of yet.

thanks in advance for any credible info ????

Not sure if it's any help or not, but I live on the Nonthaburi-BKK border canal and I go in and out of Bangkok every day.

There's a pathetic road block some days on Ratchapruek Road for traffic coming into Bangkok, but very few cars are stopped and not much at all is happening. In fact, I think they have given up even doing that much in the past days.

I guess it depends on where you're coming from? A neighbouring province?

No such thing for Bangkok - only a few provinces have such a requirement.
