Can I cross into Malaysia with Thai license plates, or do I need an ASEAN license plate?

To cross into Malaysia with Thai license plates, you need to obtain a specific document from the Konson department; without it, you may be stopped at the border. Additionally, there is an office near the border where you can acquire special plates and insurance for the crossing. One commenter mentioned that insurance was approximately 950 baht for two weeks a decade ago, and you would receive stickers with your Malay number if approved.
