Renting a Car in Thailand: I wish I knew before booking

FInally, after two road trips in Thailand, I have been able to organise this comprehensive guide to renting a car in Thailand. From selecting the right vehicle to understanding local driving customs, this guide covers everything you need to know for a successful Thai road trip.

Whether you’re planning to explore the beaches of Phuket, the mountains around Chiang Mai, or the countryside of Isaan, here’s what you should know before getting behind the wheel in Thailand.

I have rented cars in Phuket and Bangkok, the two major entry points to Thailand, and I have had such a amazing experience exploring Thailand from there, impossible to replicate with public transportation. In this post you will find a few videos created during my road trips.

Driver’s License Requirements

Can you use your home country’s driving license in Thailand? The answer is somewhat nuanced:

• For rental purposes: Most rental companies will accept your foreign driving license, provided it uses the Latin alphabet and they can read the information. If your license uses non-Latin characters (such as Chinese, Japanese, or Arabic), you may encounter difficulties.
• For legal driving: Thai law technically requires an International Driving Permit (IDP) alongside your home country license. While rental companies may not always request this document, police checkpoints—which are common throughout Thailand—will expect to see one.

If stopped without an IDP, you may face a fine of approximately $30 USD. Since an IDP costs around $20 and is easily obtained in your home country before traveling, I strongly recommend getting one. This small investment provides peace of mind and ensures you’re fully compliant with local regulations.

We got stopped twice, and likely we had an IDP because it was the first document they asked us, together with our driving license (you have to take both of them with you when driving)

Choosing the Right Vehicle Size

The ideal car size for your Thai adventure depends primarily on your group size and luggage requirements:

• Solo travelers or couples: A compact car like a Toyota Yaris or Honda City provides enough space and excellent fuel economy. These smaller vehicles are also easier to maneuver on narrow roads and in limited parking spaces. During my recent trip with my wife and child, a Toyota Yaris proved perfect—spacious enough for our needs while remaining easy to drive and park.
• Groups of 3-4: A mid-sized sedan or small SUV offers comfortable space for passengers and luggage.
• Families or larger groups: For 5-6 people, consider a larger SUV or minivan to ensure everyone travels comfortably, especially on longer journeys.

Unless you’re planning to venture deep into mountainous regions like those around Chiang Mai or Chiang Rai, engine power isn’t a significant concern in Thailand. The country’s well-maintained roads rarely require high-performance vehicles, and smaller engines offer better fuel economy in a country where you’ll likely be covering considerable distances.

Finding the Best Rental Deal

When it comes to renting a car in Thailand, you have basically options:

• Local rental agencies: Potentially cheaper but quality can vary significantly and scams are quite common
• Online booking platforms: Generally offer the best combination of price and reliability

I’ve found the most success using an aggregator website called DiscoverCars that compares quotes from multiple providers. It works similar to Airbnb, where previous customers rate rental companies on a scale from 5 to 10 stars. I usually filter between 8 and 10 stars to get only the most trusted providers. Prices usually are very competitive.

This approach has served me well for the past five years, with no rental issues across multiple Thai trips.

Insurance: Essential Coverage

Most rental vehicles come with a mandatory Third Party Liability (TPL) Insurance and a basic Collision Damage Waiver (CDW) coverage, which protects against damage to other properties and people, as well as to your rental car if you cause an accident. However, this coverage typically includes a substantial deductible—ranging from $1,000 to $5,000 USD/EUR.

To reduce or eliminate this deductible, you have three main options:

1. Credit card coverage: Some premium credit cards offer rental car insurance. This basically works as a full insurance to cover the deductible. Important, check your card benefits and activation requirements before relying on this option. Also verify if this insurance has its own excess. Mine for example has a $1,000 excess, which is still too high for me
2. Rental company insurance: Available at the rental desk, but often expensive at $20-50 per day—sometimes exceeding the cost of the rental itself.
3. Third-party insurance: For example, available through DiscoverCars for approximately $8 per day, offering excellent value for comprehensive coverage.

I personally opt for the third option, purchasing full insurance through the same aggregator where I book the car. This provides complete peace of mind at a reasonable price, allowing me to enjoy my trip without worrying about potential damage costs.

Roadside Assistance and Theft Protection is usually included by the rental company or the full insurance (double check in both cases). I always take Roadside Assistance, you never know where you end up in Thailand.

Driving on the Left Side

Thailand follows left-hand driving, similar to the United Kingdom, Australia, and Japan. If you’re already accustomed to driving on the left, you’ll feel right at home. If you typically drive on the right side, here are some tips for a smooth adjustment:

• Take it easy for the first couple of days
• Follow the flow of traffic rather than leading it
• Consider renting an automatic transmission to eliminate gear-shifting concerns
• Be especially careful at intersections and when turning

Fortunately, roundabouts are relatively uncommon in Thailand, which simplifies the adjustment for drivers used to right-side driving. Most Thai roads feature standard intersections with traffic lights, many of which helpfully display countdown timers showing seconds remaining before the light changes.

Local Driving Culture

Contrary to what you might expect, Thai drivers are generally super relaxed. During multiple trips throughout the country, I’ve rarely encountered aggressive driving or excessive speeding. Most drivers stay within 10-20 km/h of posted speed limits, creating a relatively calm driving environment.

Just keep in mind that cars remain relatively expensive in Thailand, with many locals using scooters as their primary transportation. Those who do own cars tend to drive them carefully.

The one major exception to this rule is Bangkok, where traffic congestion and complex road systems create a challenging environment even for experienced drivers. I strongly recommend avoiding car rentals in Bangkok itself—instead, use public transportation within the city and pick up your rental car when leaving for other destinations.

Traffic Conditions

Traffic conditions vary significantly across Thailand:

• Bangkok: Extremely congested at almost all hours. Avoid driving here
• Major tourist areas: Places like Phuket (especially Patong Beach) and Pattaya can experience significant traffic during peak hours and high season. However, it’s still manageable.
• Smaller cities and countryside: Generally light traffic with occasional congestion around markets or during local festivals.

During my recent Thailand road trip from Phuket I stayed for 3 days in Kamala Beach (island’s second-largest area). I experienced aceptable traffic, parking was never impossible, and overall a relatively stress-free experience, especially if compared to many Western countries.

Fuel Stations and Costs

There are plenty of petrol stations along main roads, typically every 5-10 kilometers. Major brands include PTT (the national petroleum company) and international chains like Shell.

All stations are full-service—attendants will refuel your vehicle, check tire pressure, and clean your windshield if requested and they sometimes give you even a bottle of water. This service comes at no additional cost, making refueling actually a pleasant experience.

Many fuel stations also feature convenience stores, cafes (Amazon Cafe is my favourite), and clean restrooms, making them ideal rest stops during longer journeys.

Fuel prices in Thailand are comparable to those in the United States and Australia—significantly cheaper than European prices. This makes road trips quite economical, especially when sharing costs among a group of travellers or a family. Both cash and credit cards are widely accepted at fuel stations.

Red License Plates

On my last trip, I had a rented car with a red plate. I initially thought it was a new rule for rented cars to have a specific colour, similar to when you rent a car in Cyprus.

I later found out that these are temporary plates for newly registered vehicles awaiting their permanent registration, so no special status or restriction for tourists.

Car Rental vs. Public Transportation

As you can immagine, there is no better option. It all depends on the itinerary you are planning and the type of trip you want to do.

Benefits of renting a car:

• Flexibility: The freedom to stop spontaneously at viewpoints, beaches, or interesting sites discovered along the way
• Time efficiency: No waiting for buses or taxis that may operate on “Thai time” (often running behind schedule)
• Cost-effectiveness for groups: For families or groups of three or more, a rental car often costs less than individual transport tickets
• Luggage convenience: No need to carry heavy bags between accommodations and transport hubs, especially considering the hot climate
• Access to remote areas: Many of Thailand’s most beautiful spots lie off the main tourist routes

Drawbacks of car rentals:

• Cost for solo travelers: More expensive than public transportation for individuals
• Driving responsibility: No opportunity to relax completely during transit
• Not suitable for island hopping: For trips involving multiple islands, you’ll need alternative transportation regardless

For my family of three, a rental car provided the perfect balance of convenience, cost, and flexibility. We discovered numerous unplanned spots based on local recommendations, turning what would have been a two-hour journey into a five-hour adventure filled with memorable experiences.

Road Quality and Speed Limits

First-time visitors are often surprised by Thailand’s excellent road infrastructure. The country boasts an impressive network of well-maintained roads:

• Highways: Multi-lane expressways connecting major cities, particularly around Bangkok. Speed limit: 120 km/h.
• Secondary roads: Well-paved two-lane roads connecting smaller cities and towns. Speed limits: 60-90 km/h.
• Urban streets: City and village roads with speed limits between 50-60 km/h.

During previous trips to Thailand’s northeastern Isaan region and recent explorations of the southwest coast, I’ve been consistently impressed by road quality. Even in relatively remote areas, roads are typically well-maintained with clear signage in both Thai and English on major routes.

Parking in Thailand

Finding parking in Thailand is generally less challenging than in many Western countries:

• Major tourist areas: Parking can require 5-10 minutes of searching during peak hours, but spaces are usually available.
• Paid parking: Common in busy areas, costing approximately 10-20 baht (less than $1) per hour—very reasonable by international standards.
• Hotel parking: Most hotels outside Bangkok offer free parking for guests.
• Shopping malls: Typically provide ample parking, often free for the first few hours with validation.

During my recent trip, we rarely spent more than a few minutes looking for parking, even in popular tourist destinations.

Night Driving Considerations

While Thailand’s main roads are well-lit and marked, I would not suggest driving at night in rural areas and that’s why:

• Wildlife hazards: Stray dogs, cats, and occasionally larger animals may wander onto roads after dark.
• Limited visibility: Some rural roads have minimal lighting and unexpected obstacles.
• Scooter traffic: Many local scooters have inadequate lighting, or no lighting at all, making them difficult to spot.

For these reasons, I recommend planning your itinerary to avoid night driving. In towns and cities, night driving is generally safe, though you should remain vigilant for scooters, which may appear suddenly from side streets.

Taking Cars on Ferries

There are so many amazing places to stay and visit in Thailand. If your adventure includes visiting accessible islands like Koh Lanta or Koh Chang, you’ll be pleased to know that taking your rental car on ferries is straightforward:

1. Drive to the ferry terminal
2. Purchase a ticket for your vehicle and passengers
3. Drive onto the ferry when directed
4. Enjoy the crossing
5. Drive off at your destination

The process is similar to ferry crossings worldwide, with clear signage and staff directing vehicles. Costs vary by destination but are generally reasonable.

During my recent trip to Koh Lanta, the car ferry was efficient and well-organized. The only unusual thing was that the ticket was sold 500m before the pier and we bypassed it completly because we did’t see the sign. Besides that, a great easy experience.

Electric Vehicles in Thailand

While electric vehicles are growing in popularity in Thailand, the charging infrastructure remains limited outside Bangkok:

• Major petrol stations on highways increasingly offer charging points
• Superchargers are still rare
• Most hotels do not yet provide charging facilities
• Rural areas have minimal or non-existing charging options

For this reason, I currently recommend traditional petrol vehicles for most Thai road trips, particularly if your itinerary includes smaller towns or rural areas.

Final Thoughts

Renting a car in Thailand opens up extraordinary possibilities for exploration beyond the standard tourist trail. With well-maintained roads, easy-going drivers, reasonable fuel costs, and the freedom to discover hidden gems at your own pace.
