Laos is fine for sure with a Thai, 5-year license. In theory, all other Asean countries should accept a Thai driver's license too..mine has been accepted everywhere in Cambodia but downtown Phnom Penh, where corrupt police want to see an IDP (you can get one from the Land Transport Department if you already have a Thai DL).
Also, don't trust Thai timelines. I am confident end of 2025 is more likely. Anyway, very few farang will be interested in this crossing unless you happen to live in Beung Kan.
They can't even enforce tax on their own citizens. They certainly don't have the capability of tracking down a farang who withdraws money from an ATM in Thailand and tries to steal part of it from them. Besides, they already take 220 Baht from every withdrawal.
Being Thailand, if they ever did enforce this, you'd simply need to bribe the person doing the enforcing and then it would be problem solved.
Anonymous participant Of course, if you want to explore these towns, it would make sense to catch a bus only to the first destination.
Nong Khai is nice, but might be more convenient to head directly to Udon Thani on the international bus, explore a bit then fly out (since the airport is located there; there's no airport in Nong Khai).
I've crossed into and out of Thailand through nearly every land border checkpoint the country shares with it's neighbors.
The only ones I haven't tried are the borders between Narathiwat/Yala and Malaysia, as they're located in dodgy areas, with the security situation on the Thai side quite worrying.
I also haven't tried the Phayao and Beung Kan crossings with Laos (though I've been to both, just haven't actually crossed over). I am sure I'll be crossing those in the relatively near future, especially once the new bridge in Beung Kan opens next year.
