Covid Requirements if Driving to Khon Kaen

[pj123]

I need to do a business trip to Khon Kaen next week. Planning to drive up from BKK and overnight.

Do I need vaccine/test certificates?

Although not Khon Kaen, I drove up to Nakhon Ratchisma (aka Korat) a fortnight ago and needed no documents.

Mind the floods!

I drove up to Khon Kaen and back, from Hua Hin last week.  I am currently single jabbed with AZ and as far as I could determine online, that was sufficient.  As it happened, no one asked me anyway, not even at the resort I stayed in just outside Phon.
