Driving under the influence of alcohol is a serious offense in Thailand. Foreigners who are arrested for drunk driving may face criminal prosecution, fines, imprisonment, suspension or revocation of their driving privileges, and potentially other consequences depending on the circumstances of the case.
Thailand has specific legal limits for alcohol levels in drivers. Under the current rules, the general limit is 50 milligrams of alcohol per 100 millilitres of blood. A lower limit of 20 milligrams per 100 millilitres applies to certain drivers, including persons under 20 years old.
What Is DUI in Thailand?
A person may be considered to have committed a drunk-driving offense when driving a motor vehicle with an alcohol level exceeding the legally permitted limit.
The rules apply to both Thai nationals and foreigners.
Foreign tourists should not assume that renting a car or motorcycle gives them any special exemption from Thai traffic laws.
How Is Alcohol Tested?
Thai authorities may use a breathalyzer to measure the driver's alcohol level.
If a breath test cannot be conducted, the applicable regulations provide for other testing methods, including urine or blood testing, subject to the requirements of the law.
A foreigner who does not understand Thai should request an interpreter or appropriate assistance before signing documents or making statements that may affect the criminal case.
What Happens If a Foreigner Is Arrested for DUI?
If a foreigner is arrested for suspected drunk driving, the case may proceed through several stages:
- 01Police stop and investigationThe driver is stopped and investigated by the police.
- 02Alcohol testingThe driver's alcohol level may be tested.
- 03ArrestThe driver may be arrested if the authorities have grounds to believe an offense has occurred.
- 04Police investigation and evidencePolice prepare the investigation and collect evidence.
- 05Bail or custodyThe suspect may be released on bail or remain in custody depending on the circumstances.
- 06Submission to the prosecutorThe case may be submitted to the prosecutor.
- 07Prosecution before the courtThe prosecution may proceed before the Thai court.
- 08Judgment and penaltyThe court determines whether the accused is guilty and imposes the appropriate penalty.
The exact procedure can vary depending on the facts, including whether an accident or injury occurred.
What Are the Penalties for DUI?
The consequences of drunk driving depend on the circumstances and seriousness of the offense.
A straightforward DUI case may result in a fine, imprisonment, or both, together with consequences relating to the driver's license.
However, the situation can become considerably more serious if the driver causes:
- A traffic accident
- Property damage
- Serious bodily injury
- Death
- Injury to multiple people
Where an accident causes serious injury or death, the driver may face additional criminal charges beyond the basic DUI offense.
Therefore, foreigners should not assume that a DUI case is simply a matter of paying a fine.
Can a Foreigner Be Jailed for DUI?
Yes.
A foreigner can be arrested and prosecuted in Thailand for drunk driving. Whether the person remains in custody, receives bail, or is ultimately sentenced to imprisonment depends on the applicable law and the facts of the individual case.
The possibility of imprisonment becomes particularly important where the case involves an accident, injury, death, repeat offending, or other aggravating circumstances.
Can a Foreigner Get Bail?
A foreign defendant may be able to apply for bail.
However, bail is not automatic. The authorities or court may consider the nature of the offense, the potential penalty, the risk of flight, the defendant's circumstances, and the security offered.
Thailand's government guidance confirms that foreigners suspected of criminal offenses may be eligible for bail in appropriate circumstances, although the applicable conditions and amount depend on the offense.
A foreigner should therefore contact a Thai lawyer as soon as possible after an arrest.
What If the Foreigner Was Driving a Motorcycle?
Motorcycle DUI cases are common among foreign tourists, particularly in Thailand's major tourist destinations.
Foreigners should also make sure that they are legally entitled to drive the particular vehicle in Thailand.
For example, the Royal Thai Embassy advises foreign visitors that an international driving permit should be carried together with the passport and national driving license when driving in Thailand.
If a foreigner is stopped while driving without the appropriate license and is also suspected of DUI, there may be more than one legal issue involved.
What If There Was an Accident?
A DUI case becomes significantly more serious when an accident causes injury or death.
The authorities may investigate:
- The driver's alcohol level
- Speed and manner of driving
- Road and weather conditions
- Witness statements
- CCTV footage
- Vehicle damage
- Medical records
- Whether the driver had a valid license
- Whether other traffic offenses were committed
If another person is injured or killed, the driver may face additional criminal and civil liability.
The victim may also have rights to claim compensation for medical expenses, loss of income, property damage, and other legally recoverable losses.
Can DUI Affect a Foreigner's Visa or Immigration Status?
A DUI case can create immigration concerns for a foreign national, particularly when the case results in a criminal conviction or imprisonment.
Thai immigration law contains provisions concerning persons whose circumstances may affect their eligibility to enter or remain in Thailand, including certain persons who have been imprisoned by court judgment or whose conduct may present a danger to public safety.
The immigration consequences depend on the circumstances and should be assessed separately from the criminal case.
A foreigner should therefore not assume that paying a fine automatically resolves every immigration issue.
What Should a Foreigner Do After a DUI Arrest?
If you are a foreigner arrested for DUI in Thailand, you should:
- Contact a Thai criminal lawyer as soon as possible.
- Request an interpreter if you do not understand Thai.
- Carefully review documents before signing them.
- Keep copies of police and court documents.
- Do not make inaccurate statements to the authorities.
- Inform your embassy or consulate where appropriate.
- Ask your lawyer about bail.
- If an accident occurred, obtain advice concerning potential civil liability and compensation claims.
- Ask about possible immigration consequences.
Early legal advice can be particularly important if the DUI involves an accident, injury, death, or another criminal offense.
DUI and Foreign Tourists in Thailand
Thailand has specifically reminded foreign tourists to understand Thai traffic and drink-driving laws.
Tourists should also remember that Thai traffic laws apply regardless of nationality.
The fact that a person is visiting Thailand for only a few days does not prevent the authorities from arresting and prosecuting that person for a traffic offense.
Conclusion
DUI in Thailand can have serious consequences for foreigners.
Depending on the circumstances, a foreign driver may face arrest, criminal prosecution, fines, imprisonment, driving-license consequences, civil liability, and potential immigration problems.
The consequences can be significantly more serious when drunk driving results in an accident, serious injury, or death.
If you are a foreigner who has been stopped, arrested, or charged with DUI in Thailand, obtaining advice from a Thai criminal lawyer promptly can help you understand your rights, the criminal procedure, bail options, and potential immigration consequences.
