Weird Laws Around the World That Can Actually Fine You

A traveler picks a stray Thai coin up off a Chiang Mai sidewalk, sets it back down with the sole of a shoe to keep it from blowing away, and within the hour is being questioned by police about an insult to the monarchy. It sounds invented. It is not: Thailand’s royal insult law covers the king’s image on currency, and it has produced real prosecutions. That is the gap this guide closes. Not a list of trivia, but the rules that are actually enforced in 2026, organized by category, with the country, how it is enforced, and the fine or consequence a traveler realistically risks.

The highest-stakes enforced rules for travelers are Thailand’s royal insult law (up to 15 years in prison for insulting the monarchy or defacing currency bearing the king’s image), the UAE’s public decency code (fines from AED 1,000 to 100,000 plus deportation for public affection or swearing), strict drug-import rules in Japan (Adderall is banned outright, even with a prescription), and the Maldives’ total alcohol ban outside licensed resorts. Dress codes, drone rules and littering fines add up fast but carry lower risk. Several viral “weird law” claims, like Switzerland’s 10pm toilet ban, are myths.

Public behaviour and order

These are the rules that catch travelers who assume “public order” means the same thing everywhere. It does not, and several governments enforce it with fines that scale fast for repeat offenses.

CountryThe ruleRealistic fine or consequence
UAE (Dubai)Public affection, aggressive arguing or rude gesturesFine of AED 1,000 to 100,000 (roughly $270 to $27,000), often paired with deportation
ThailandVaping, including disposable e-cigarettesFine up to 40,000 baht (about $1,150); repeat offenses can bring up to 5 years in prison
SingaporeImporting, selling or chewing gum (non-therapeutic)Fine up to SGD 1,000 for personal possession, far higher for import or sale
AustriaLoud arguments, public affection or strong-smelling food on trainsOn the spot fine and removal from the train
Spain (Barcelona)Walking shirtless or in swimwear away from the beachFine up to €300

The UAE rule is the one worth taking seriously before a layover in Singapore and onward into the Gulf: local lawyers who track enforcement note that married couples have been prosecuted for the same public affection as unmarried ones, so “we’re married” is not a defense. The gum law in Singapore is the most famous entry on any weird-laws list precisely because it is real, dates to 1992, and is still actively enforced at customs.

Dress codes and religious sites

Dress-code breaches rarely cost money directly. They cost a wasted trip to a site a traveler flew a long way to see, or in rarer cases an arrest.

CountryThe ruleRealistic fine or consequence
ThailandBare shoulders or knees inside a templeTurned away at the door, no re-entry until covered
UAERevealing clothing in malls, mosques or outside resort beachesPolice caution or fine on repeated complaints
Sri LankaPosing with your back to a Buddha statue, or climbing on oneArrest, and same-day deportation in publicized cases
Jamaica and other Caribbean nations (Barbados, Grenada, St Lucia, Bahamas, Trinidad and Tobago)Wearing camouflage-pattern clothingFine up to $2,000, garment confiscated on the spot
Italy (Rome)Sitting or lingering on the Spanish StepsFine of €160 to €400

The Caribbean camouflage ban surprises the most travelers because it has nothing to do with fashion offense: in these countries only military and police wear camouflage patterns, so a tourist in cargo shorts with a camo print reads as impersonating a uniform. Checking the dress code before flying into the UAE avoids the same guesswork at the airport.

Photography, drones and sensitive sites

A camera or a drone is the single most common reason a traveler’s gear gets confiscated at a border. The rule is rarely about the photo itself, it is about what the equipment can be mistaken for.

CountryThe ruleRealistic fine or consequence
MoroccoBringing in or flying a drone without declaring itConfiscation at customs plus a fine near 1,165 dirhams (about €110)
UAE (Dubai)Flying a drone without an Emirates-ID-linked registrationEffectively closed to tourists; undeclared drones are flagged and confiscated at customs X-ray
UAEPhotographing people, government buildings or military sites without consentFine, device confiscation, possible detention
GreecePhotographing military installations or restricted zonesDetention and confiscation of camera or footage

The drone rule is the one that trips up experienced travelers, since a drone is legal to own everywhere and the traveler has usually just forgotten it is in the bag. Declaring it at check-in, or leaving it home for a Morocco or Gulf itinerary, is cheaper than the confiscation.

Customs, medication and border rules

This is the category with the highest arrest risk for an ordinary traveler, because the offending item is usually a prescription medication packed without a second thought.

CountryThe ruleRealistic fine or consequence
JapanCarrying Adderall or other amphetamine-based medicationArrest and detention, no exception for a foreign prescription
JapanCold medicine containing pseudoephedrine (Sudafed, Vicks inhalers)Confiscated unless cleared in advance with a yakkan shoumei import permit
JapanCodeine above a small personal-use quantityImport license required from the Narcotics Control Department, applied for 14+ days ahead
UAECarrying codeine or other opioid painkillers without a permitArrest and prosecution under narcotics law
SingaporeCodeine exceeding the personal allowancePrior approval required, seizure if undeclared
MaldivesBringing any alcohol into the country, even sealed duty-freeConfiscated permanently if not bonded; drinking outside a licensed resort risks arrest and deportation

Adderall is the sharpest example here because the usual defenses do not apply. A valid prescription, a customs declaration form, even a doctor’s note: none of it changes the outcome in Japan, where the medication itself is the banned substance. The fix is always the same: check a destination’s controlled-substance list against every prescription before departure, not after.

Compare the countries on your route

Multi-country trips mean multiple legal cultures back to back, and the rule that applies in one stop can be nonexistent in the next.

Money, currency and royalty

Only one country produces genuine arrest risk in this category, and it is worth understanding in full before assuming it is exaggerated tourist folklore.

CountryThe ruleRealistic fine or consequence
ThailandInsulting, defaming or threatening the monarchy, in person or online3 to 15 years in prison per count under Section 112, applies to foreigners and to acts committed abroad
ThailandStepping on or defacing a banknote or coin bearing the king’s imageTreated as a royal insult; has led to real arrests

Thailand’s lese majeste law is described by legal observers as one of the strictest criminal-defamation statutes in the world, and it is not limited to speeches or protests. A social media comment, a joke told to a stranger, or a coin picked up carelessly can all trigger a prosecution. Foreign governments issue advisories on this specific law for a reason: ignorance of it is not a defense once a case is opened.

Environment, heritage and nature

The newest wave of “weird laws” is really old heritage protection catching up with tourist volume. Sites worn down by decades of visitors now carry fines that used to be warnings.

CountryThe ruleRealistic fine or consequence
Italy (Venice)Feeding pigeons in the historic centerOn the spot fine up to €500
FranceTaking sand, pebbles or shells from a beachFine up to €1,500 for a bag full
Italy (Eraclea)Building sandcastles on the public beachFine, actively enforced by beach patrols
GreeceWearing high heels at the Acropolis and other ancient sitesFine or refusal of entry; the rule protects the stone from damage
United States (Arizona)Cutting down or seriously damaging a saguaro cactusFelony charge, up to 25 years in prison for destroying a protected cactus

The pattern across this category is protection, not punishment for its own sake. Venice banned pigeon feeding in 2008 because droppings were eating into centuries-old stonework, not because the birds bothered anyone. The Acropolis heel rule works the same way: the ban exists because stiletto heels concentrate enough pressure to chip ancient marble that foot traffic alone does not damage.

The famous weird laws that are not real

Every roundup of enforced law also carries a handful of stories that keep circulating because they are funnier than the truth. None of these belong in a serious pre-trip checklist.

  • Switzerland bans flushing the toilet after 10pm. No federal or cantonal law exists. The confusion comes from standard building quiet hours (roughly 10pm to 7am) that some apartments enforce as a private house rule, not a government statute.
  • France makes it illegal to name a pig Napoleon. Often cited as a 19th-century ordinance. There is no current French statute banning it, and no official checks for it.
  • The UK bans dying inside the Houses of Parliament. A popular urban legend with no underlying law. Parliament has no jurisdiction over where a person’s death legally occurs.
  • Japan fines people for being overweight. The “Metabo Law” sets voluntary waist-measurement targets employers report on, it does not fine individual citizens or visitors.
  • Jaywalking is illegal everywhere. It is genuinely enforced in Singapore, Germany and Switzerland, but is not a legal concept at all in the UK or the Philippines. “Everywhere” is the part that is false.
  • Kissing on French train platforms is illegal. An old, unenforced early-1900s railway byelaw gets recirculated as current law. No one has been fined under it in living memory.

The pattern behind every debunked myth here is the same: a real, narrow local custom, a quiet-hours rule, an old unenforced ordinance, a patchwork of city bylaws, gets flattened into a single dramatic headline about an entire country. A trip through Switzerland is not going to end at a police station over a flush timer, whatever the meme claims.

Key takeaways

  • Thailand’s currency and royal-insult rules carry the heaviest realistic risk of anything on this list: years in prison, not a fine.
  • Medication is the most common way an ordinary traveler ends up in real legal trouble. Check every prescription against the destination’s controlled-substance list before packing it.
  • Dress-code and photography rules cost the least in money but the most in wasted time: a temple visit refused, a camera confiscated at a checkpoint.
  • Most viral “weird law” stories are myths. The boring, enforced rules are the ones worth remembering.

Before you go

A short pre-trip check beats memorizing a list. Confirm three things for every country on the itinerary before departure.

  • What is banned at the border. Cross-check every prescription medication, and any drone, against that country’s customs and narcotics rules, not a general packing list.
  • What draws a fine in public. Dress code, affection, photography and littering rules vary by city as much as by country; check the specific destination, not the region.
  • What is treated as a serious offense rather than a fine. A handful of rules, royal insult laws and hard drug-import bans chief among them, sit in a different risk category entirely from a gum fine or a beach-shell ticket.

Government travel advisories and the destination’s own embassy site are the only sources worth trusting over a listicle, this one included.

FAQ

01What is the most severe “weird law” a tourist can actually break?

Thailand’s lese majeste law. Insulting, defaming or threatening the monarchy, including stepping on a banknote bearing the king’s image, carries 3 to 15 years in prison per count and applies to foreigners as well as citizens.

02Is it really illegal to chew gum in Singapore?

Yes. Importing, selling or distributing chewing gum has been banned since 1992, with an exception for prescribed therapeutic gum. Fines for personal possession can reach SGD 1,000, and far more for import or sale.

03Is Adderall really illegal to bring into Japan, even with a prescription?

Yes. Adderall and other amphetamine-based medications are banned outright in Japan. A foreign prescription and a customs declaration do not create an exception, and travelers carrying it risk arrest and detention.

04Can tourists bring alcohol into the Maldives?

Not into the country generally. Alcohol is legal only inside licensed resorts, resort hotels and some liveaboard boats. Undeclared alcohol is confiscated permanently, and drinking outside a licensed resort or on a local island can lead to arrest and deportation.

05Do UAE public affection laws apply to married couples too?

Yes. UAE law does not distinguish between married and unmarried couples for public decency offenses, and documented cases include married couples fined or prosecuted for kissing in public.

06Is it true that Switzerland bans flushing the toilet after 10pm?

No. This is a debunked myth. No Swiss federal or cantonal law restricts flushing at night. Some buildings enforce standard quiet hours as a private house rule, which is not the same as a government statute.
