Driving from BKK to Krabi

Has anyone been driving down south last two days?

We're planing to drive down tomorrow, take the road Around Samut Sakhon.

If you have, or some stretches of the road, were there any extra controls etc?

I expect some, but really don't want to take the chance to end up in some provincial quarantine/lockdown just cause we pass through, so thought I would check if anyone has first hand info on Nakhon Pathom, Ratchaburi, Petchaburi, Prachuab and Chumphon etc.
