Leaving Phuket in a Rental Car

What to ask the rental company

The conversation takes a couple of minutes and removes almost every risk of the trip. The first question is whether the agreement permits leaving Phuket at all: some cars carry that restriction by default, and people usually find out afterwards. The second is whether the insurance works beyond the island, because cover is sometimes tied to territory.

Five questions worth asking out loud

Is there a mileage limit and what counts as exceeding it. Who recovers the car and how if it fails on the mainland, since companies rarely send their own truck that far and work through partners instead. Does the trip have to be announced in advance and in what form. Is there a second set of keys and where is it kept. Get the answers in writing in the chat, because a dispute a week later is won by whoever kept the correspondence.

The second set of keys sounds like a detail right up to the moment one is locked in the boot a hundred kilometres from the office. Ask what happens then: is a duplicate brought out, or is the car opened on the spot at your expense.

How the exit works

Phuket is joined to the mainland by the Sarasin bridge at the northern tip of the island. There is one road to it and it is straightforward: highway 402 Thepkrasattri runs from the south through Thalang, past the airport, and ends at the bridge. Further north it reaches the junction at Khok Kloi, and that is where the route really divides.

At Khok Kloi you join highway 4, Phetkasem. East along it lies Phang Nga and then Krabi. North lies Takua Pa and Khao Lak. It is easy to take the wrong exit there, because the signs alternate between Thai and English and the turning you want is labelled with a town you are not going to.

How long the drive takes

Khao Lak is around an hour and a half at a relaxed pace, the town of Phang Nga an hour and a half to two, Krabi about three. Those figures hold if you have not caught the morning flow on the 402: the section from Kathu and Thalang towards the bridge collects everybody heading for the airport, and during departure hours it is dense. Setting off early in the morning or after lunch is the sensible option.

What it means for the car

Mainland roads differ from island ones in speed and in the length of the runs. In Phuket you rarely hold a steady pace for longer than twenty minutes, while on highway 4 you drive for hours, and the car works differently: higher consumption, more heat, and any wheel imbalance becomes obvious. A crossover is more comfortable than an economy car here not because of ground clearance but because of the seating position and stability on long straights with lorries.

Check three things before you set off that short island trips forgive: tyre pressure, coolant level and the air conditioning at idle. Look at the spare as well, not for its presence but for its pressure.

Fuel stations on highway 4 appear regularly, but there are long empty stretches between them, and on the turnings to the national parks there may be none at all. The island habit of refuelling when the light comes on works badly on the mainland. Keep the tank at least half full and do not pass a large station counting on the next one.

Before the bridge

Fill up in Thalang rather than hoping for the first station across the water. It is a two minute stop that removes an hour of thinking about it later.

Police and fines beyond the island

Checkpoints on highway 4 are more frequent than on the island, and stops there are calm and routine. The documents have to be with you: passport, a licence of the right category and the car's papers from the glovebox. The International Driving Permit is asked for, and not having it on the mainland costs more than a conversation on a beach road in Chalong.

Fines for speed and for seatbelts reach the rental company later, sometimes after you have already handed the car back. That is why the owner holds the deposit for a while after the return. If you were stopped and given a notice, say so at the handover rather than hoping the paper will disappear.

Driving on the left is the same on the mainland, but the rhythm is different. Overtakes are longer, speeds are higher, and the island assumption that everybody drives slowly does not apply.

One more thing visitors notice: the lorry traffic on highway 4 is heavy and steady, and it sets the pace. Fitting into it calmly is easier than trying to make progress through it.

Planning a day trip

Khao Lak genuinely works as a day trip: leave early, arrive by lunch, back in the evening. Phang Nga fits too, if the stops are not stretched. Krabi in a day is a bad idea: three hours each way turns the trip into six hours of driving plus everything else, and you will be coming back in the dark on an unfamiliar road.

Why darkness changes the calculation

At night on the mainland highways you meet unlit motorcycles and machinery without reflectors, and the markings are worn away in places. Coming back after dark is the main risk factor of the whole route rather than the road itself. Plan to reach the bridge before sunset.

Parking on the mainland is easier than on the island: there is almost always space at restaurants and viewpoints. The surprise comes on the other side, because the flow back onto Phuket along the 402 is often denser than the flow out, and the last twenty kilometres to your hotel take longer than you allowed.

Take water, cash for tolls and park entries, and a plan for where you will stop. Long mainland stretches have fewer places to pull in than the island has, and improvising is less pleasant at hour four than at hour one.
