Driving with drugs in the body and causing a traffic accident in Vietnam can lead to serious legal consequences, especially when the incident causes injury or significant damage.

For many foreigners living, working, or traveling in Vietnam, suddenly having to work with the police after such an accident often causes confusion and anxiety.

Understanding Vietnamese legal regulations and the appropriate steps to take from the beginning can help reduce legal risks and protect your rights. So under Vietnamese law, how may this situation be handled?

Vietnamese legal regulations on driving with drugs in the body

Vietnamese law considers operating a vehicle while having drugs in the body to be a prohibited act, even if the driver did not directly consume drugs immediately before driving.

This is clearly stipulated in the Law on Road Traffic Order and Safety 2024 and related administrative sanction regulations.

However, when this behavior causes a traffic accident, especially one involving injuries or serious damage, the driver may face criminal liability, not just administrative penalties.

Administrative penalties for driving with drugs in the body

According to Decree 100/2019/ND-CP (amended by Decree 123/2021/ND-CP), drivers who have drugs in their body may face:

  • A fine of 30,000,000 – 40,000,000 VND for car drivers

  • Suspension of driving license for 22 – 24 months

  • Possible temporary confiscation of the vehicle

For foreigners, in addition to the above penalties, other consequences may arise, such as:

  • Exit restrictions during the investigation period

  • Possible criminal prosecution if serious consequences occur

It is important to understand that once a traffic accident occurs, the case is often assessed from a criminal law perspective, especially if injuries or significant property damage are involved.

When can the case be subject to criminal liability?

In many situations, driving with drugs in the body and causing a traffic accident may be considered under Article 260 of the Criminal Code 2015 (amended 2017) regarding:

The crime of violating regulations on road traffic participation.

Some circumstances that may increase criminal liability include:

  • Causing serious injury to another person

  • Causing death

  • Causing large property damage

  • The driver used alcohol or drugs

According to Clause 2, Article 260, if the driver used drugs and caused serious consequences, the penalty frame may be:

03 – 10 years imprisonment

In cases with particularly serious consequences (for example, multiple deaths), the sentence may be higher.

However, it should be noted that the specific penalty always depends on many factors of the case, including the level of fault, actual consequences, cooperation attitude, and mitigating circumstances.

Investigation process when a foreigner is involved in a traffic accident involving drugs

When a foreigner is found to have drugs in the body after a traffic accident, Vietnamese authorities often conduct a relatively strict investigation process.

Understanding these steps can help the person involved reduce anxiety and prepare better from a legal perspective.

Common investigation steps

Typically, the case may go through the following stages:

1. Scene inspection and drug testing

Traffic police or investigators may:

  • Examine the accident scene

  • Conduct a rapid drug test

  • Send the driver for medical testing

The test results are usually one of the important pieces of evidence in the case file.

2. Taking statements and determining fault

Investigators may:

  • Take statements from the parties involved

  • Determine speed and direction of movement

  • Extract traffic camera footage if available

The goal is to determine the cause of the accident and the degree of fault of each party.

3. Criminal prosecution (if there are criminal signs)

If there are signs of violating road traffic regulations, investigators may:

  • Initiate a criminal case

  • Charge the suspect

  • Apply preventive measures (for example: travel restriction)

In some serious cases, the person involved may be detained for investigation purposes.

Common legal risks foreigners may face

Based on experience working with many international clients, several issues often create difficulties for foreigners involved in traffic cases in Vietnam.

1. Lack of understanding of the legal process

Vietnam’s legal system differs in many aspects from Europe or the United States, especially regarding:

  • Investigation procedures

  • The role of lawyers

  • Detention and temporary custody periods

2. Language barriers

In many situations, foreigners:

  • Do not understand the contents of official records

  • Do not fully know their legal rights when working with investigators

This may lead to statements that are unfavorable to themselves.

3. Psychological pressure during criminal investigation

A traffic accident can quickly become a serious criminal case, causing many people to panic and make poorly considered decisions.

Legal solutions and what should be done immediately after the incident

If you or a relative is a foreigner involved in a traffic accident in Vietnam involving drugs, handling the situation correctly from the beginning may significantly affect the entire case process.

Important steps to consider

Lawyers often recommend several key steps:

1. Cooperate but understand your rights

You should:

  • Cooperate with investigators

  • Provide truthful information

However, you also have the right to consult with a lawyer before giving important statements.

2. Involve a lawyer as early as possible

A lawyer can assist with:

  • Explaining legal procedures

  • Reviewing the legality of investigation procedures

  • Protecting your rights during questioning

Early legal assistance may help avoid mistakes that could become disadvantageous later.

3. Actively remedy the consequences

According to Vietnamese judicial practice:

  • Supporting medical expenses

  • Providing compensation

  • Showing goodwill to remedy the consequences

may be considered mitigating circumstances in criminal liability.

However, compensation actions should be carried out under appropriate legal advice to avoid additional risks.

The role of a lawyer when foreigners are investigated in traffic cases in Vietnam

For foreigners, being involved in a criminal case in Vietnam can be extremely stressful.

A lawyer experienced in criminal cases involving foreign elements can assist in several important ways:

  • Explaining Vietnamese law in English

  • Working with investigators

  • Supporting families and embassies

  • Building an appropriate legal strategy at each stage of the case

In Vietnam, every case has unique details, so legal risk assessment must always be based on the specific facts and evidence of the case.

If you or your family member is a foreigner being invited to work with police, under investigation, or involved in a criminal case in Vietnam, seeking legal advice early can help you better understand the situation and choose the appropriate legal approach.
