Message on WhatsAppThailand treats scooters and motorbikes as motorcycles for this purpose.
In real life, many tourists still ride without proper bike documents. If the police stop you, the fine is usually around 500 to 1,000 THB. People often keep the checkpoint paper for the next day or two and avoid another fine, but that is local habit, not legal permission.
Some tourists are offered fake help to "add" a motorcycle category to an IDP. This is a bad idea. If the category in the IDP does not match the national license, it can be treated as document fraud. Thai police are familiar with this trick.
Usually yes, but that does not automatically make riding legal.
Usually around 500 to 1,000 THB.
In practice, often for a day or two with the checkpoint paper, but that is not an official permit.
No. In Thailand, category A is what matters in practice.
