When driving around Thailand one meets police check points. Generally at province borders. It's up to the individual officer to decide if he wants you to stop and answer questions and or show documentation or just waved through.
If you are in the jungle, close to a national boundary, the border police, if you meet them, can act similarly.
Both and all options have been experienced by me. Driving with my Thai wife and alone and walking along jungle tracks close to the border.
Do you ever get up off your lazyboy?
