Fines and traffic rules in Phuket: what bike renters need to know

A holiday in Phuket almost always involves renting a vehicle. A motorbike is a convenient way to get around the island, but along with freedom, it requires attention and responsibility. To avoid unpleasant situations and fines, it is important to know the basic rules of the road and the peculiarities of local driving.

💡 Tip: if you don’t feel confident on a motorbike, are travelling with children or prefer comfort, choose a car. It is safer and more convenient. Proven car and motorbike rental options are available at HolyCowPhuket.com.

Left-hand traffic

The main thing to remember is that Thailand has left-hand traffic. This is unusual for tourists, especially in the early days. Keep to the left lane, but don’t hug the edge: cars often emerge from driveways and courtyards, and you may not be noticed.

At roundabouts, traffic moves clockwise — give way to those already on the roundabout. At T-junctions, you are allowed to turn left on red if you are in the far left lane and are not obstructing others. Watch for signs — sometimes this turn is indicated by a separate arrow.

Speed limits

In Phuket, speed limits vary depending on the section of road:

• In built-up areas: 40–50 km/h.
• Outside built-up areas: 70–90 km/h.

Keep an eye out for ‘Slow’ warning signs — they are often placed before sharp bends or descents. The roads on the island are winding, and visibility can be limited due to hills.

During the rainy season (May to October), the asphalt becomes slippery, so slow down. At night, lighting is poor, and animals may appear on the roads — be especially careful.

Basic rules and features of driving

Standard traffic rules apply in Phuket, but there are some nuances:

• Give way to pedestrians — formally, this is mandatory, although locals often ignore it.
• Flashing headlights mean a request to give way.
• If someone honks at you, don’t be alarmed, it’s not aggression, but a warning: ‘I’m here, be careful.’
• Don’t change lanes abruptly and always use your indicators.
• Do not drive against the flow of traffic or on the pavement.
• Motorcycles often drive between lanes — keep this in mind when changing lanes.

Local drivers drive a little chaotically, but predictably: they rarely exceed the speed limit. The main thing is to stay calm and keep your distance.

Helmets are mandatory

According to Thai law, both the driver and passenger must wear helmets. The fine is up to 2,000 baht, but in practice it is around 500–1,000 baht ‘on the spot’. The police actively conduct raids, especially in tourist areas (Patong, Kata, Karon).

Do not wear old helmets without fasteners or visors — they will not protect you in the event of a fall. It is better to buy your own helmet at Big C or Lotus supermarket — they cost from 500 baht, but they will keep you safe.

Carry your documents with you

When riding a motorbike, you must have:

• An international driving licence (category A).
• A copy of your passport with a stamp showing your entry into Thailand.

If the police stop you without a licence, you will be fined up to 10,000 baht (officially) or ~1,000 baht on the spot. Sometimes the bike may be impounded until you present your documents.

If you have left your passport as collateral for the rental, carry a photocopy with you. It is also useful to have a copy of your insurance policy, especially if you are renting from official companies through HolyCowPhuket.com.
