I was released from ASQ in Bangkok this past Thursday, August 12. I hired a driver and private car, recommended by the hotel, with Bangkok plates. We encountered two roadblocks, one of which wasn't staffed. At the second one, in Saraphi, the driver was of much more interest than me. he explained that I has been in the U.S. for vaccination (technically true; I'd gone to Guam) and had just completed ASQ in Bangkok. I had a ream of documents available with proof of vaccination, home address, PCR tests; but no interest from the officer.
Instead, the officer made the driver, who claimed he had received two doses of Sinopharm, download a QR code onto his phone and promise he'd turn around right after dropping me off at home and leave CM province.
I've read multiple sources that indicate I don't need to do home quarantine in CM now since I just completed ASQ, got in a car and my first stop was a toilet break outside a red zone and I had no contact with anyone during that stop or any subsequent stop. We didn't eat or drink anything during the quick eight hour trip in order to keep wearing our masks.
