Regarding inter-provincial travel: I am aware that there are restrictions and potential (home) quarantine requirements when going from certain higher risk areas to some provinces. TAT (see link) provices a helpful summary about individual province's regulations. The questions that bugs me is: What is the definition of coming from a "high risk / high controlled" area? Say I am taking my car and drive from one low risk area (say Chiang Mai) to another low risk province ( say the south of Thailand). I would naturally have to cross some of the higher controlled areas in central Thailand (e.g. using the highway through Samut Sakhon). Does this count as coming from a highly controlled area upon arrival? What if I just drive through and not stop overnight? Any first hand experiences with this? Much appreciated!
