What car rental in Siam, Bangkok covers

This section explains what you actually get when you book self-drive car rental in Siam, Bangkok with Rent-Trip: how many cars sit on this page, which classes they fall into, what the price includes, and how the hand-over is arranged. The booking itself is agreed with a manager before anything is fixed.

How many cars are available for car rental in Siam, Bangkok

We keep 115 cars on this page, split across 11 classes that run from ฿700 to ฿35,000 per day. Electric is the biggest group at 32 cars starting from ฿1,050, followed by Economy with 15 cars from ฿700, Crossovers with 12 from ฿1,100 and Minivans with 11 from ฿1,300.

What car rental in Siam, Bangkok includes

• VAT 7%: already inside the price you see, so ฿700 a day means ฿700 a day.
• Compulsory Por Ror Bor insurance: attached to every registered car and covering injury to third parties.
• Class 1 cover: covers damage to the car itself; its terms and the excess are set out in the rental agreement.
• Clean car, full tank: the car is handed over washed with a full tank of fuel.
• Rental from 1 day: a single day in the city does not require a week-long booking.
• A bank card in the main driver's name: used for the security hold, with the amount set out in the agreement.

The minimum driver age is 21, and the conditions for drivers under 25 and for premium classes are set out in the rental agreement rather than decided at the kerb.

How the booking and hand-over work

You tell us the delivery address, the date and the time, and a manager confirms all three before the booking is fixed. We deliver the car to any address in Bangkok, and a delivery fee, if there is one, is agreed when booking — nothing about it is decided at the last minute. Delivery anywhere else is arranged case by case and is not promised on the site. Bring your passport, your home driving licence, an International Driving Permit unless you hold an ASEAN licence, and a bank card in the main driver's name.

Choosing your car for rental in Siam, Bangkok

Eleven classes sit behind the 115 cars on this page, from Economy at ฿700 a day to Exotic at ฿35,000, with seating for 2 to 12 people. Which one you take depends on where you are going: a hatchback for Siam and Pathum Wan, a seven-seater or a pickup for a run out of town.

Classes and prices for car rental in Siam, Bangkok

Which models suit a city trip in Siam, Bangkok

Nissan March and Suzuki Ciaz at ฿700 a day are the cheapest cars on this page, and BYD Dolphin at ฿1,050 is the cheapest electric for city driving. All three are five-seaters with automatic transmission: March and Ciaz run a 1.2 L petrol engine, Dolphin is a 95 hp electric hatchback. Automatic transmission is standard across these models, so the left-hand traffic here takes one less thing to think about.

Seven seats and pickups for car rental in Siam, Bangkok

• Toyota Veloz: 7 seats at ฿1,300 a day, 1.5 L petrol, automatic — the cheapest way to move a group of seven.
• Toyota Hilux Revo Double Cab: 5 seats at ฿1,600, 2.4 L diesel, automatic, rear-wheel drive.
• Toyota Hilux Revo Smart Cab: 2 seats at ฿1,700, 2.4 L diesel, manual — built for cargo, not passengers.

The Smart Cab is the one to avoid if you are carrying people — two seats and a manual gearbox make it a load carrier, not a family car.

What rental in Siam, Bangkok costs

Our daily range runs from ฿700 to ฿35,000, and the longer you book, the lower the day works out. The rate you see is the rate you pay for the class you pick — VAT 7% is already inside it.

Daily, weekly and monthly rates for car rental in Siam, Bangkok

Weekly bookings are priced at daily x 6, from ฿4,200, and monthly bookings at daily x 21, from ฿14,700. A seven-day booking of the cheapest Economy car at ฿700 a day comes to ฿4,200 rather than ฿4,900, and a 30-day booking of the same car to ฿14,700 rather than ฿21,000 — the multipliers are the only discount mechanism on this page. The same arithmetic applies up the fleet: a Premium car from ฿3,500 a day runs from ฿21,000 a week and ฿73,500 a month, and an Exotic from ฿35,000 a day from ฿210,000 a week. If a five-day trip may become a week, it is worth settling the length of the booking before it is fixed. Hire is available from 1 day, so a short city trip does not force a weekly commitment.

What affects the price of car rental in Siam, Bangkok

• Class: Economy starts at ฿700, Electric at ฿1,050, Crossovers at ฿1,100, Minivans at ฿1,300, Premium at ฿3,500, Sports at ฿15,000 and Exotic at ฿35,000 per day.
• Number of days: a daily rate, a weekly rate at daily x 6 or a monthly rate at daily x 21 — nothing else changes the per-day figure.
• Delivery address: the address, the date and the time are agreed with a manager before the booking is fixed, and a delivery fee, if any, is agreed at the same moment.
• Security hold: a bank card in the main driver's name is used for it, and the amount is set out in the rental agreement.
• Insurance excess: Class 1 cover for damage to the car is part of the deal, but its terms and the excess are set out in the rental agreement.
• Driver's age: the minimum is 21, and conditions for drivers under 25 and for premium classes are set out in the agreement.

Everything outside that short list — the deposit, the excess, any discount scheme — is written into the rental agreement rather than quoted as a number here.

Documents for car rental in Siam, Bangkok

Paperwork for car rental in Siam, Bangkok comes down to four items: a passport, a home driving licence, an International Driving Permit, and a bank card in the main driver's name. Thailand keeps to the left and every car is right-hand drive, so the licence check matters as much as the car itself.

What you need to bring to the hand-over

• Home driving licence: your national licence, valid and unexpired, held for the class of car you are booking.
• Bank card in the main driver's name: used for the security hold; the amount is set out in the rental agreement.
• ASEAN nationals: a national licence from an ASEAN country is enough, with no International Driving Permit required.

Why the permit is not optional

A foreign visitor needs a home driving licence plus an International Driving Permit, and the police fine for driving without one runs ฿500–1,000. Citizens of ASEAN countries drive on their national licence and skip this step entirely.

Insurance attached to the car

Compulsory motor insurance, Por Ror Bor, covers injury to third parties and is attached to every registered car. Since 30 December 2025 a car rental agreement is a contract controlled by the OCPB, written in Thai, with all fees and penalties disclosed inside it. Traffic-camera fines are issued to the car owner and re-invoiced to the renter, so a camera on Motorway 7 reaches you through us rather than arriving in your post. Read the Thai agreement before you sign it — the fees are all listed there, and asking about the excess at hand-over costs nothing.

Driving and parking with car rental in Siam, Bangkok

Siam sits at the centre of a city that drives on the left, so every car in our fleet is right-hand drive and the controls are on the right. Plan your turns around that before you leave the delivery address.

Speed limits and cameras on the way out of Siam

• Outside built-up areas: 90 km/h once you clear the city boundary on ordinary roads.
• Motorways: 120 km/h on Motorway 7 (Bangkok – Chonburi – Pattaya – Map Ta Phut) and Motorway 9, the outer Kanchanaphisek ring.
• Cameras: on Motorway 7 the 120 km/h limit is enforced primarily by speed cameras, and a camera fine is issued to the car owner — that is, to the rental company — and re-invoiced to the renter.

Tolls, parking and the M-Flow trap

A short expressway hop runs roughly ฿50–100 for a passenger car. Motorway 7 charges at nine payment points and takes cash or M-PASS/Easy Pass; from the Lat Krabang entrance it is ฿25 to Bang Bo, ฿100 to Pong and ฿105 to Pattaya, so a full Bangkok–Pattaya run lands around ฿105–130. Motorway 9 runs barrier-free on M-Flow, where a camera reads the plate and the bill follows later: without registration you have two days to pay by plate number, from the third day the tariff doubles, and it escalates to the tariff plus 2x plus a penalty of ten times the tariff.

Parking at Bangkok's big malls is the easy part. CentralWorld gives two hours free, then ฿20 an hour, and ฿50 an hour after six hours. ICONSIAM gives two hours free, charges ฿30 for the third hour and ฿60 an hour after seven. Terminal 21 Asok gives three hours free, ฿20 an hour for hours four to six and ฿50 an hour from the seventh. Central Bangna gives six hours free, and Esplanade Ratchada, PARA Pinklao and Central Festival Eastville are free outright.

Delivery and hand-over of your rental in Siam, Bangkok

You name the spot, we confirm the slot, and the car arrives there.

Where we deliver in Siam, Bangkok

• Any address in the city: hotels, condos, offices and private residences, with the exact point agreed when booking.
• Don Mueang Airport (DMK): both terminals, T1 for international arrivals and T2 for domestic.
• Elsewhere: arranged case by case, and not promised on the site until a manager confirms it.

The delivery address, the date and the time are agreed before the booking is fixed — a delivery fee, if there is one, is agreed at the same moment.

What happens at hand-over

The car comes clean and with a full tank, and the booking runs from a single day upward, so a two-day Siam trip is a normal request rather than a special one. Since 30 December 2025 a car rental agreement in Thailand is a contract controlled by the OCPB, written in Thai, with all fees and penalties disclosed in it, so the document you get is the one that governs the booking.

Documents to have ready

• Home driving licence: the national licence you already hold.
• International Driving Permit: required alongside the national licence for visitors from outside ASEAN under the 1949 Geneva Convention and section 42 bis of the Motor Vehicle Act; ASEAN citizens drive on their national licence.
• Bank card: in the main driver's name, used for the security hold.

Driving without the permit carries a police fine of ฿500–1,000, and an insurer may refuse a claim — so the permit is worth sorting before you fly, not at the kerb. Send the manager the exact pin and a contact number the day before, because a lobby with two entrances can put the driver at the wrong one.

Insurance and rental terms in Siam, Bangkok

Insurance and rental terms sit in one document, and that document is what matters when something goes wrong. Since 30 December 2025 a rental agreement is a contract controlled by the OCPB: it is written in Thai, and all fees and penalties are disclosed in it. Here is what we can state plainly, and what is settled on paper.

What cover comes with the car in Siam, Bangkok

Two layers travel with every registered vehicle, and they do different jobs. The compulsory layer, Por Ror Bor, answers for injury caused to other people; the first-class layer, Class 1, answers for harm to the vehicle itself. That split matters more than it looks: the compulsory policy follows the car rather than the driver, so a claim arising from someone else's injuries is handled through the vehicle's own cover. Class 1 is the layer standing behind the car you are driving, and what it pays for, what it leaves out and what you pay before it starts paying are all written into the agreement you receive. Rent-Trip hands over the car with both policies in place; the numbers behind them are not something to guess at from a website.

Documents and the security hold for car rental in Siam, Bangkok

• IDP exemption: citizens of ASEAN countries may drive on their national licence, with no permit required.
• Bank card: a bank card in the main driver's name is used for the security hold; the amount is set out in the agreement.
• Age: minimum driver age is 21; conditions for drivers under 25 and for premium classes are set out in the agreement.
• Fines: traffic-camera fines are issued to the car owner and re-invoiced to the renter.

The police fine for driving without a permit is ฿500–1,000, and an insurer may refuse a claim — that is the practical reason the permit line is not negotiable. Traffic in Thailand keeps to the left and every car is right-hand drive, so the first hour behind the wheel is the one to take slowly.

What we agree when booking

VAT 7% is included in the prices shown, and the rental agreement carries the rest: the deposit, the excess, delivery fees and any conditions that apply to your class or your driver profile. Delivery across Bangkok and to Suvarnabhumi Airport (BKK) and Don Mueang Airport (DMK) is arranged the same way: the address, the date and the time are agreed with a manager, and a delivery fee, if any, is agreed when booking. Delivery anywhere else is arranged case by case and is not promised on the site.

Practical tips for car rental in Siam, Bangkok

A car is worth having for the trips that leave this grid — Ayutthaya, Kanchanaburi, Khao Yai, Pattaya — and for the airport runs, where the delivery address, the date and the time are agreed with a manager before the booking is fixed.

What to sort out before the car arrives

• International Driving Permit: a foreign visitor needs a home driving licence plus an IDP under the 1949 Geneva Convention; the police fine for driving without one is ฿500–1,000 and an insurer may refuse a claim. ASEAN nationals drive on their national licence.
• Children under six: a child seat to the TISI standard is required, and below 135 cm a seat belt or a special seat; the fine runs up to ฿2,000.
• Fuel: gasohol 95 at ฿39.94 a litre and gasohol 91 at ฿39.57, diesel B7 at ฿41.44. The car is handed over with a full tank, so refill before you return it.

Getting through the city

Traffic keeps to the left and every car is right-hand drive, which takes an afternoon to get used to. The speed limit is 80 km/h in built-up areas, 90 km/h outside them, 120 km/h on Motorway 7 and 110 km/h on the expressways. Motorway 7, 149.3 km from the capital to Map Ta Phut, is the road you take south; from the Lat Krabang entry a four-wheel car pays ฿25 to Bang Bo, ฿100 to Pong and ฿105 to Pattaya. On the outer ring, Motorway 9 uses M-Flow: no barrier, a camera reads the plate and the bill follows. Parking there is straightforward — CentralWorld gives two hours free, then ฿20 an hour, and ฿50 an hour after six; ICONSIAM gives two hours free, ฿30 for the third hour and ฿60 an hour after seven. Street parking is another matter, so use the mall car parks.

Fines and the paperwork

Traffic-camera fines are issued to the car owner and re-invoiced to the renter, so a speeding ticket on Motorway 7 reaches us and then you. Since 30 December 2025 a car rental agreement is a contract controlled by the OCPB, written in Thai, with all fees and penalties disclosed in it. The minimum driver age is 21, and the conditions for drivers under 25, for premium classes, for the security hold and for Class 1 insurance are set out in that agreement.
