Weird Laws in Thailand You Should Definitely Avoid Breaking

Thailand is known for its stunning beaches, golden temples, spicy street food, and warm hospitality — but it also has some surprisingly strict (and sometimes strange) laws that travelers often overlook.

Whether you’re backpacking through Chiang Mai, island-hopping in the south, or getting lost in Bangkok’s markets, here are a few Thai laws that might sound weird… but are very real.

1. Don’t Step on Thai Currency

Why? Because it has the King’s face on it.

In Thailand, the royal family is deeply respected — and stepping on money (which features the King) is seen as hugely disrespectful. It could even land you in legal trouble.

Pro tip: If you drop a coin, let it roll a bit. Don’t stomp it with your foot.

2. Don’t Disrespect the Monarchy

Thailand has one of the strictest lèse majesté laws in the world. Speaking badly about the King or royal family — even as a joke — is illegal and can result in prison time.

Rule of thumb: Avoid political conversations or sharing memes about the monarchy, even online.

3. Don’t Drive Shirtless or Braless

Driving a motorbike or car without a shirt (or just in a bikini top) is technically illegal. While it’s not always enforced in tourist spots, it’s still against the law — and you could be fined.

Keep it classy: Cover up while cruising, even in the heat.

4. Don’t Litter — Especially Gum

Thailand takes public cleanliness seriously. Littering, including spitting gum on the street, can result in heavy fines — or worse, jail time.

FYI: In some areas, you need to carry your trash until you find a proper bin.

5. No Vapes or E-Cigarettes

Thailand has a total ban on vaping. It’s illegal to possess or use e-cigarettes or vape pens, and customs officials do confiscate them. Tourists have even been detained over it.

Just don’t: Leave the vape at home.

6. Be Careful with Buddha Images

It’s illegal to buy or export Buddha statues out of Thailand (unless you’re authorized). Even tattoos of Buddha are controversial and can be considered disrespectful.

Be mindful: Avoid Buddha-themed souvenirs unless they’re small and approved for export.

7. Don’t Go Commando

Yep — going out in public without underwear is actually illegal in Thailand, even if no one knows.

While no one’s checking: Technically, it’s part of the dress code law. So maybe pack that extra pair.

Final Thoughts:

Thailand is beautiful, vibrant, and full of life — but respecting local laws and culture is key to a good trip. When in doubt, be polite, dress modestly, and ask locals or guides if you’re unsure about something.
