Can you carry a passenger on a scooter in Bali?

The rule: one passenger, two helmets

A scooter in Bali is built for one rider and one passenger, and the law reflects that. Carrying a single pillion is legal; carrying two or more passengers is not. Both rider and passenger must wear an SNI-standard helmet, and each unhelmeted person is a separate fine of up to IDR 250,000.

You will see whole Balinese families of four on one bike. That is normal locally, but it is not legal, and as a foreign rider you are far more likely to be stopped and fined for it. Stick to one passenger.

Children as passengers

Indonesian law sets no minimum age for a scooter passenger, and in practice small children ride all the time, often seated between two adults. What police do enforce is the helmet: a child without one is a fine, and children’s helmets are sold cheaply across the island. Bear in mind a young child’s feet cannot reach the footpegs and their grip is weak, so the handling warning below matters even more with a child aboard.

The under-told detail: weight, luggage and the surfboard question

Most articles stop at "one passenger is fine". The part that actually matters for a tired traveller is what that second person does to the bike — and what you are allowed to strap to it.

A 110–125cc automatic scooter carrying two adults accelerates slowly, brakes over a much longer distance and feels top-heavy at low speed — exactly when you are pulling out of a car park or filtering through Canggu traffic. If both of you are new to scooters, this is the single biggest hidden risk: the person on the back leaning the wrong way, or shifting weight suddenly, can unbalance the bike. Agree before you set off that the passenger keeps their feet on the pegs at all times, holds the grab rail or your waist, and stays passive in corners — they should lean with the bike, never against it.

On luggage: a passenger holding a suitcase, a large backpack worn high, or a surfboard rack sticking out to the side all change the bike’s balance and width, and a wide load is both dangerous and an easy thing for police to pull you over for. Surfboards are usually carried on a proper side-rack fitted by board-hire and surf shops, ridden slowly and solo — not with a passenger as well. If you have real luggage to move (airport runs, checking out of a villa), a car with a driver is safer and barely more expensive than the risk.
