Traffic & Scooter Rules (The Tourist Trap)
Renting a scooter is the #1 way tourists get fined or injured in Phuket, Chiang Mai, and Samui.
-
License Requirement: A standard car driver's license is NOT valid. You need a Full Motorcycle License from your home country PLUS an International Driving Permit (IDP) with the motorcycle stamp.
-
The Checkpoint: Police set up daily checkpoints in tourist zones. No IDP? Instant fine (usually 500-2,000 THB), and your insurance is voided.
-
Helmet Law: Helmets are mandatory for both the driver and the passenger.

-

2. Cannabis: The "Grey Area" (⚠️ 2026 Update)
You will still see cannabis shops everywhere, and yes, you can buy it easily. However, the laws have shifted back towards "Medical Use" in late 2025, creating a risky environment for careless tourists.
-
Buying: Shops are open, but many now require you to sign a "medical consultation" form or show ID to comply with new regulations. It is not the "Wild West" anymore; ensure you buy from licensed dispensaries, not street stalls.
-
The Real Danger (Public Nuisance): This is where tourists get caught. Smoking in public is illegal. If the smoke or smell bothers someone, you can be charged under the Public Health Act with a fine of 25,000 THB or 3 months in jail.
-
Advice: Smoke only in private areas or designated smoking lounges inside dispensaries. Do not smoke on the street, at the beach, or on hotel balconies where neighbors can smell it.
3. Alcohol Restrictions
-
Buying Hours: Good news! As of late 2025/early 2026, Thailand has lifted the afternoon alcohol ban (formerly 2 PM - 5 PM). You can now buy alcohol during the day.
-
Religious Holidays: Alcohol sales are completely banned on major Buddhist holidays (e.g., Makha Bucha, Visakha Bucha). Bars will be closed.

Weird & Niche Laws (Must Know)
-
Playing Cards Limit: Under the Playing Cards Act, you cannot possess more than 120 playing cards (approx. 2 decks) without government approval. Police have raided bridge clubs in the past. Leave the extra decks at home.
-
Stepping on Money: As mentioned, stepping on a rolling coin or bill to stop it is a crime because you are stepping on the King's image.
-
Buddha Images: It is illegal to take Buddha statues out of the country without a permit (souvenirs larger than 12cm often require paperwork).
Cultural Taboos (Don't Be Rude)
-
Temples (Wats): Cover your shoulders and knees. No crop tops or short shorts. Take off your shoes before entering the main prayer hall.
-
The Head & Feet: The head is sacred; never touch a Thai person's head (even kids). The feet are dirty; never point your feet at a Buddha statue or a person.
-
Respect the Anthem: If you are in a public park or train station at 8:00 AM or 6:00 PM, the national anthem will play. You must stop moving and stand still until it finishes.
Stay Connected to Stay Safe
Police checkpoints, changing laws, and language barriers make having internet access non-negotiable. You need Google Maps to see where the red zones are and Google Translate to talk to authorities if stopped.
-
Avoid Scams: Use ride-hailing apps (Grab/Bolt) instead of negotiating with Tuk-tuks to avoid being overcharged.
-
Recommendation: Don't rely on spotty hotel WiFi. Get a Thailand eSIM before you land. It connects instantly to local 5G networks.
