Speed Limits in Phuket: What Applies to a Rental Car
In a car in Phuket you may do 80 km/h in towns and community zones, 90 km/h outside them, and 100 km/h on stretches outside town with two lanes each way and a real central barrier. Those are the national maximums from Thailand's 2021 speed regulation (B.E. 2564). A sign with a smaller number beats all three, and on the hills and beach streets here you will usually be well under any of them anyway.

What is the speed limit for a car in Phuket?
Three numbers. That's the whole rule for a car: 80, 90, 100.
Which one applies depends on the place, not the road number. In a town, a municipal area or a signed community zone, it is 80 km/h. Leave those behind and it becomes 90. Get onto a stretch outside town with at least two lanes each way and a proper physical barrier down the middle (raised, sunken, or a rail) and you may do 100. A painted line in the middle doesn't count, which catches people out.
Where do those numbers come from?
We checked the regulation itself rather than a travel forum. It is the Ministerial Regulation Prescribing Speed Limits for Driving on Roadways, B.E. 2564 (2021), made under the Land Traffic Act and published in the Royal Gazette, volume 138, issue 77, replacing limits dating back to 1979. Two lines in it matter for visitors: a lower posted number always applies, and in zones signed as dangerous or slow you slow down further.

What that means for the car
On Phuket the legal maximum is rarely the speed you can actually drive. The island is small, the towns run into one another, and much of the traffic you share the road with is scooters, some of them without a rear light after dark.
The hill roads are the clearest case. The passes into Patong, Karon and Kata have tight bends and long descents where 80 km/h would be dangerous, whatever the regulation allows. There the right speed is set by the bend and by the low gear you should be in on the way down, not by a number.
Where you will see the higher limits is on the long, straight main roads between the airport, Thalang and the south. That is also where the speed cameras stand, so the straight sections are exactly where it pays to watch the speedometer.
- Town, beach area or community zone — up to 80 km/h
- Open road outside those areas — up to 90 km/h
- Outside, two lanes each way and a physical barrier — up to 100 km/h
- Any sign with a lower number — the sign is the limit
- Frontage roads beside a main road — the town limit, 80 km/h
Are the limits different for scooters?
Yes, they are lower. The same regulation gives motorcycles 60 km/h in towns and community zones, 70 km/h outside them and 80 km/h on the divided multi-lane roads.
Big bikes are treated differently: machines of 400 cc or more, or with 35 kW or more, may do 80, 90 and 100 km/h in the same three situations. Heavy trucks over 2,200 kg and buses with more than fifteen passenger seats have their own, lower limits, which is why a queue behind a lorry on the climb out of town is simply part of driving here.
ImportantA camera fine does not stop you at the roadside. It reaches the rental company later and is settled with the driver named on the agreement, so a fast run down the airport road can turn up on your bill after you have flown home.
Where are the speed cameras in Phuket?
On the straight sections, where the road invites you to speed up: the road in from the airport, the bypass near Thalang and the highway down to Chalong.
The simple habit is to hold the limit on every long straight, even at night when the road is empty. The detail on how the fines reach you is in speed cameras and fines in Phuket, and the wider rules of the road in Thai road rules for drivers.
How fast should I really drive on Phuket's roads?
Slower than the sign in most places. In the towns and beach areas, the traffic, the pedestrians and the scooters pulling out of side streets set a pace well below 80 km/h.
At night, in heavy rain and on your first day on the left side of the road, give yourself more margin still. The drive from Patong to the airport or from Kata to Chalong does not get meaningfully shorter at a higher speed, because the time is lost at roundabouts and in town, not on the open stretches.
The long straight run south
The Thalang to Chalong drive is about 30 km and takes in most of the straights listed above. At a steady legal speed, the route planner's 35–40 minutes in clear traffic hold. The minutes are lost at the junctions near town, not on the open road.

Common questions
What is the speed limit in Phuket towns?
80 km/h for cars in towns, municipal areas and community zones, under the 2021 Ministerial Regulation. If a sign shows a lower number, that number applies.
What is the speed limit on Phuket highways?
90 km/h for cars outside towns and community zones. Where the road has two or more lanes each way and a physical central barrier, it is 100 km/h.
What is the speed limit for scooters in Phuket?
60 km/h in towns and community zones, 70 km/h outside them and 80 km/h on divided multi-lane roads. Bikes of 400 cc or more have higher limits.
Does a road sign override the general speed limit?
Yes, when it shows a lower number. The regulation says a posted lower limit replaces the general one on that road or lane.
Who pays a speed camera fine on a rental car?
The driver named on the agreement. The fine reaches the rental company later and is settled with the renter, even after the trip.
Which law sets the speed limits in Thailand?
The Ministerial Regulation Prescribing Speed Limits for Driving on Roadways of 2021. Its Thai year is B.E. 2564, it was issued under the Land Traffic Act, and it was published in the Royal Gazette.
