Carrying ID and handling a police check

Foreigners in Thailand are legally required to be able to produce their passport (with the current entry stamp or visa) on demand — Section 40 of the Immigration Act B.E. 2522 (1979) requires a foreigner to carry it and show it to an immigration or police officer when asked. In practice most people carry a clear photo or copy of the passport photo page and visa stamp for everyday outings and keep the original secure, but strictly the law expects the document itself, and at a formal check a copy may not satisfy the officer.

Roadside and street checks do happen, particularly of riders and in nightlife areas. A lawful traffic fine is issued as a ticket, against which you pay at a police station or designated point; if an officer proposes settling a matter informally on the spot, you are entitled to ask for the official ticket and to pay the stated fine rather than anything more. Stay calm, polite and cooperative; do not run a checkpoint; and remember the Tourist Police line 1155 offers English-language help and can assist if you feel a check is not being handled properly. Nothing here is a substitute for compliance — carry your documents, wear the helmet, and keep the interaction courteous.
