Hey there Patig! Welcome to OpenStreetMap and thanks for your awesome contributions! Just a quick heads up, if the road doesn't have a sign indicating a max speed of 40km/h, it's best to remove the tag. You can find more information about this topic in this forum post: https://community.openstreetmap.org/t/review-speed-limit-cases-in-thailand-that-have-mph/97428/2. Keep up the great work!
