Bangkok BTS Skytrain Etiquette Guide: 6 Do's & 7 Don'ts Every Traveller Should Know

For visitors exploring Bangkok and the capital's office workers alike, the BTS Skytrain serves as the primary rapid transit system connecting major landmarks across the city. However, a recent viral incident involving foreign tourists creating excessive noise onboard has sparked questions about what is — and isn't — permitted on Bangkok's elevated rail network. The BTS maintains clear rules and prohibitions designed to ensure safety, order and comfort for all passengers.

BTS Rules and Prohibitions at a Glance

Quick Summary (TL;DR)

No eating or drinking of any kind on platforms or inside trains
No loud noise or speakerphone use that disturbs other passengers
No pets of any kind allowed (guide dogs and police dogs excepted)

No smoking or vaping anywhere within the BTS system
No leaning against train doors or obstructing entry and exit points

6 BTS Passenger Courtesies (Do's)

Being a considerate BTS passenger makes everyone's journey smoother. Here are the courtesies worth practising:

Wear headphones and keep your voice down: When watching videos, listening to music or taking calls, always use headphones and speak softly to avoid disturbing fellow passengers.
Queue behind the yellow line: While waiting for the train, form orderly queues at the marked spots on the platform and always stand behind the yellow safety line.
Let passengers exit first: When doors open, leave a clear centre passage for those inside to disembark before boarding in an orderly fashion.
Give up priority seats: Offer your seat to children, pregnant women, the elderly, monks and passengers with disabilities.
Wear your backpack on your front when crowded: During peak hours, removing your backpack and holding it in front or lowering it frees up space and reduces accidental bumps.
Hold onto handrails or straps: Maintain a firm grip while the train is moving for your own safety, and avoid getting so absorbed in your phone that you lose awareness of your surroundings.

7 BTS Prohibitions (Don'ts)

To ensure safety, hygiene and order, the BTS enforces the following non-negotiable rules:

1. No loud noise or speakerphone use (fines apply)

Per BTS regulations, passengers must not create excessive noise, cause disturbances or engage in arguments without reasonable cause. Playing videos or music through phone speakers, or conducting loud phone conversations inside the carriage is prohibited.

2. No eating or drinking

A common question: "Can I bring my bubble tea or water bottle onboard?" The answer: you may carry sealed drinks, but consuming them is strictly forbidden from the moment you pass through the ticket gates onto the platform and throughout your journey inside the train.

3. No pets allowed

Even small dogs or cats carried inside bags are not permitted in the BTS system. The sole exceptions are guide dogs for visually impaired passengers and working police dogs.

4. No strong-smelling items or balloons

Durian and pungent foods: Absolutely prohibited — the odour affects all passengers inside the enclosed system.
Gas-filled balloons: Banned from platforms and trains as they may drift into overhead power lines, potentially disrupting train operations.

5. No smoking or vaping

The entire BTS system is a legally designated smoke-free zone. Smoking, vaping or using any electronic heating device is prohibited, with fines applicable under Thai law.

6. No leaning against doors

Leaning against carriage doors is strictly prohibited while the train is in motion. Doing so risks door-lock malfunctions or falls when the doors open at the next station.

7. No dangerous items or oversized objects

Weapons, explosives, flammable substances, hazardous chemicals and non-folding large bicycles are prohibited throughout the system.
