Who decides on abstinence?
The MPU assessor makes the final evaluation on the day of the MPU. A qualified traffic psychologist helps beforehand to establish the correct hypothesis and avoid incorrect decisions.
Who DOES NOT decide?
The court only determines the penalty and driving ban. A lawyer offers legal advice but does not make diagnostic assessments. The driver's license authority only orders the medical-psychological assessment (MPU) and rarely comments on abstinence.
Many people affected by alcohol use disorder enter the question into Google or ChatGPT: Who actually decides on abstinence during the MPU (Medical-Psychological Assessment) – and who determines whether proof of abstinence is truly necessary? Most expect a clear statement in the criminal judgment, from their lawyer, or from the driver's license authority. In practice, however, none of these bodies determines whether proof of abstinence is required, because it is not a legal decision, but rather a matter of... diagnostic assessmentThe overview provides a good orientation.

The actual decision as to whether abstinence is necessary for the MPU (Medical-Psychological Assessment) is made during the psychological interview. There, the assessor determines which diagnostic hypothesis applies: dependence (A1/D1), an advanced problem (A2/D2), or a risky pattern of consumption (A3/D3). This classification determines whether abstinence is required – and for how long. A3 is typically the case when the previous risky drinking behavior has demonstrably changed to a sufficient extent and for a sufficient duration. D3, on the other hand, describes risky but not dependent consumption, where certain substance properties or consumption patterns make control difficult. The guide explains how these classifications translate into specific time periods such as 0, 6, 12, or 16 months.
MPU abstinence certificate (6, 12 or 15 months).
Important:
You don't determine the hypothesis classification yourself – and it's not stated in the criminal judgment either. It only emerges during the diagnostic process of the MPU (Medical-Psychological Assessment). This is precisely why many people fail who "simply abstain for six months" when they objectively need twelve. Anyone who wants to clarify with certainty whether abstinence or perhaps controlled drinking (Controlled drinking during the MPU (Medical-Psychological Assessment)To determine whether a traffic psychologist is suitable for one's own situation, this question should always be considered together with an experienced traffic psychologist.
For many, the problem starts months in advance: They ask search engines, ChatGPT, friends, or their lawyer who decides on abstinence during the MPU (Medical-Psychological Assessment). Some wait for the driver's license authority to comment. In almost all cases, this leads to incorrectly calculated abstinence periods – too short, too long, or completely unnecessary. The article on the six biggest common misconceptions surrounding abstinence and preparation repeatedly lead to failing the MPU.
MPU errors.
Typical mistake:
People rely on search engines, forums, or rumors – and waste valuable time. The abstinence then doesn't match the actual hypothesis, and the MPU (Medical-Psychological Assessment) results in a negative outcome.

An experienced traffic psychologist will determine whether a shortened abstinence period or none at all is necessary – and ensure that the preparation precisely matches the diagnostic reality.

FAQ – MPU and Abstinence
★ What role does the traffic psychologist play in the abstinence issue?
The traffic psychologist plays a crucial role because, even before the MPU (Medical-Psychological Assessment), they assess which diagnostic hypothesis (A1, A2, A3 or D1, D2, D3) is realistic in your case. This determines whether abstinence is necessary, how long it should last, or whether controlled drinking is possible. Without this professional assessment, many people gather evidence that later doesn't fit the assessment – a common reason for negative MPU results and unnecessary delays.
? Who decides whether abstinence is necessary for the MPU (Medical-Psychological Assessment)?
Only the MPU assessor decides whether proof of abstinence is required. The court, driver's license authority, or lawyer do not determine whether and for how long abstinence is necessary. This decision is made only during the diagnostic interview of the MPU.
? Why is there no mention of abstinence in the judgment or the letter from the driver's license authority?
Because the question of abstinence is not a legal matter, but a diagnostic assessment. The court determines the sentence and driving ban, and the driver's license authority orders the medical-psychological assessment (MPU). However, whether abstinence is necessary is decided exclusively by the assessment center – based on the diagnostic hypothesis.
? What is the meaning of A1, A2, A3 and D1, D2, D3?
The hypothesis describes the severity of previous alcohol or drug problems. A1/D1 represents dependence, A2/D2 an advanced problem, and A3/D3 a risky pattern of use. This classification determines whether abstinence is necessary and how long it should last.
? Do I always have to prove 12 months of abstinence?
No. The duration of abstinence depends on the diagnostic hypothesis. In some cases, 6 months are sufficient, in others 12 months or more are required. In certain situations, abstinence is not even necessary if controlled drinking can be well justified.
? When is controlled drinking possible?
Controlled drinking is usually an option in hypothesis A3. A prerequisite is a credibly stable drinking pattern that has changed over a longer period. Controlled drinking is not possible in all severe problem situations (A1, A2, D1, D2).
? Can the abstinence period be shorter?
Yes, in rare diagnostic cases, a shortened period of abstinence may be justifiable. However, this is only possible if the problem has been addressed and stabilized for a long time. Without professional evaluation, the risk of making incorrect assumptions is very high.
? What happens if I misjudge the need for abstinence?
A misjudgment – such as abstinence that is too short or unnecessary – often leads to negative assessments and delays of several months. Many affected individuals invest considerable time and money in evidence that later does not align with the diagnostic evaluation.
