[3][4] Due to the introduction of very powerful and heavy motorcycles, the Department of Land Transport is introducing a new regulation.

Once the regulation is effective, drivers who want to drive a motorcycle with the power exceeding 45 kW or the engine larger than 400 cc must have an additional licence as well as more stringent training.

Anyone who has completed a sentence of imprisonment and who has been discharged for at least three years shall be considered fit for a public driving licence.

The exception is that a probationary motorcycle licence may be issued to people aged 15–17 years old (inclusive).

However, the Military Automobile Act, 1933 empowered the Department of Army Transportation to issue driving licences to soldiers.

[6] Once they are ready, they must obtain a medical certificate confirming that they are free from active tuberculosis, elephantiasis, leprosy, alcoholism, drug addiction and other potential conditions affecting the ability to drive and public safety[12] before attending tests at the Department of Land Transport or any local land transport offices.

On the other hand, drivers who fail to pass one or more manoeuvres must get the appointment slip and attend the test again.

[5] Since the appointment slots at land transport offices in large provinces are often occupied for many months, some learner drivers may attend an approved driving school, available locally, or the Land Transport School in Bangkok and Pathum Thani.

After the completion of programme, the driver must pass both theory and practical test, overseen by approved invigilators.

Regardless of timeframe, the driver must pass a physical test again in order to be able to hold a further licence.

If, however, the licence has expired for more than 1 but less than 3 years, the holder must attend the lecture and pass the theory test.

[17][18] For a licence under the Automobile Act, the annual fee is ฿100 for cars and ฿50 for motorcycles and other vehicles.

For A and P licences issued under the Land Transport Act, the annual fee is ฿50, plus an additional charge of ฿50.

[19] For example, If the licence is lost, stolen or significantly defaced, the driver should apply for a replacement within 15 days.

[6] For car and motorcycle licences issued under the Automobile Act, the replacement fee is half the original fee (excluding paperwork charge); the maximum payable charge is capped at ฿100.

To sum up, the following table shows the replacement cost of driving licences.
