Driver’s licenses in Thailand are not all the same, especially for commercial vehicles or cargo transportation like trucks. These vehicles require specific license types that match the vehicle’s classification and purpose. As of 2025, the Department of Land Transport has clearly defined four main types of truck driver’s licenses.

1. Type 1 License (B.1 / T.1)

Permitted vehicles:

• Passenger cars

• Pickup trucks

• Vans

• Taxis

• 4-wheel trucks not subject to restricted operating hours

License type:

• B.1 – For private vehicles (white plates)

• T.1 – For public/commercial vehicles (yellow plates)

2. Type 2 License (B.2 / T.2)

Permitted vehicles:

• 6-wheel trucks

• 10-wheel trucks

• 12-wheel trucks (non-trailers)

• Buses and public transport vehicles

License type:

• B.2 – For private vehicles (white plates)

Key Notes for Truck Driver’s Licenses:

• Licenses beginning with “B.” are for private use

• Licenses beginning with “T.” are for public/commercial use

• Driving with the wrong license type is a legal offense

• Drivers transporting hazardous goods must undergo special safety training

In 2025, truck driver’s licenses in Thailand are clearly categorized into four types based on the vehicle type and its usage. Using the correct license ensures safety and compliance with the law. If you’re a logistics business owner or a commercial truck driver, always verify the vehicle type and your license before starting work.

Stay prepared, stay safe – both in terms of licensing and vehicle readiness. Reliability starts with responsibility.
