What is an MPU and why do I need it?

The medical-psychological assessment is a way for the driver’s licensing authority to clarify specific questions related to your fitness to drive. In general, the assessment aims to clarify whether you can be expected to drive a motor vehicle safely and in accordance with legal provisions. The questions in your assessment are set by the driver’s licensing authority, based on the circumstances that led to your fitness to drive being called into doubt. The driver’s licensing authority can also set several different sets of questions.

How much does the MPU cost?

The costs for an MPU are very different and the prices vary depending on the question and the scope of the examination. The price starts at about 530 € and can reach more than 1000 €, depending on effort and additional costs. Thus there are single questions as well as double and multiple questions, which cost more, because corresponding additional expenditure results. On certain occasions (alcohol, drugs and medication) additional laboratory tests are necessary. For each individual case, it is recommended that you contact the relevant MPU office of TÜV Hessen in order to find out the price directly. The basis for the price is the fixed question (or several questions) of the driving licence authority, which is stated on the information letter on the MPU request by the driving licence authority to you. Here you will find the addresses and telephone numbers of the TÜV Hessen assessment centres for driving fitness.

Where can I undergo the MPU?

You can undergo the assessment at any officially certified assessment center for driver aptitude. Once you have chosen a center, please inform your driver’s licensing authority. TÜV Hessen has several officially certified assessment centers for driver aptitude in the states of Hesse, Rhineland-Palatinate, Lower Saxony and North-Rhine Westphalia. 

How do I get an appointment for the MPU?

Before an MPU can take place, you must apply for a driver’s license at your local driver’s license authority. The authority will then inform you whether an MPU is necessary, as well as the reasons why. If you need to undergo an MPU, you will be asked to inform the authority of the assessment center that will perform the MPU. The authority will then send your driver’s license record to the selected assessment center. Once the TÜV Hessen assessment center has received your file, we will contact you to arrange an appointment for the assessment.

When do I get my driver’s license back?

If your driver’s license has been withdrawn, you cannot apply for a driver’s license at your local driver’s licensing authority until three months before the end of the retention period. The decision on whether to re-issue your driver’s license lies with the driver’s licensing authority. If you are requested to provide an MPU report, the authority will only return your driver’s license once you have submitted a positive report.

What happens during the MPU?

The medical-psychological assessment is performed by an experienced traffic medicine specialist and an experienced traffic psychologist. The assessment consists of three sections. First, you will answer some questions on your previous history and your health, before completing a number of aptitude tests that aim to assess your awareness, concentration and reactions. The scope of the aptitude tests also depends partly on the class of driver’s license for which you have applied. The medical section of the MPU consists of a medical interview and a general physical examination that focuses on the physical requirements for driving. If you are required to undergo an MPU for drug-related reasons, you will also be asked to provide a urine sample, regardless of any proof of abstinence. If you have been referred for alcohol-related reasons, the doctor will take a blood sample. In the psychological interview, you will be able to describe the circumstances that led to you losing your driver’s license and being referred for the MPU. This requires you to recognize the reasons for your problematic behavior that led to the withdrawal of your driver’s license at the time of the MPU. It is also important that you are able to show that you have permanently changed your behavior.

Do I need to prepare for the MPU?

The concerns of the driver’s licensing authority can only be addressed if you have recognized the reasons for your problematic behavior, and have changed your behavior in a positive and sustainable manner. Expert consultation can help provide answers to questions about the causes and necessary changes in your behavior, and can also highlight any other necessary measures. MPU consultations are offered by traffic psychologists or traffic psychology institutes. These are independent of the driver aptitude assessment centers. The assessment centers are not allowed to provide any consultation or preparatory measures.

Where can I find expert advice or help with preparation?

You can tell whether a consultant is providing you with expert advice by their qualifications, for example. This advice is usually provided by a psychologist with a bachelor’s or master’s degree and who specializes in traffic psychology. They should provide you with clear and transparent information about the services and related costs before the assessment. You should also sign an agreement in which all conditions are laid out. The costs for expert preparation can vary greatly from case to case, and depend in particular on the number of sessions required. Consultants or therapists from addiction counseling centers with experience in driver aptitude diagnosis can also help you. Important: Please stay away from providers of preparation support services who offer to create previous histories that will apparently convince the assessors. This also applies to providers that offer “MPU guarantees” or money-back guarantees. No one can guarantee that you will pass the MPU. You must confront your past thoroughly and honestly, and change your behavior so you will not experience problems like the withdrawal of your driver’s license in future.

Do I need to memorize anything for the psychologist? Do I have to tell the truth?

If you read the previous question, the answer to this question will be clear already. If you have confronted your past thoroughly and honestly, and have changed your behavior, it should be easy for you to describe your experiences in a clear and convincing way. It is therefore not a good idea to memorize certain answers. The assessor will thoroughly check whether you have sufficiently recognized the mistakes you made and the circumstances that led to your problematic behavior, as well as whether you have permanently changed your behavior. Being open and honest in the assessment interview is very important if you want to clear any doubts the driver’s licensing authority may have about your suitability to drive.

Will the psychologist try to trap me or use psychological tricks?

In the interview, the psychologist wants to objectively assess the progress of the change in your behavior. They will not lay any traps for you or use any tricks. The psychologist certainly does not wish you any harm, and you will not be asked to stack balls or stand on your head, no matter what your friends may have told you.

Is the assessment report sent automatically to the driver’s licensing authority?

We only send the assessment report to the driver’s license authority if you have authorized us to do so through your signature, which releases us from our duty of confidentiality. Otherwise, you are the only person who will receive the assessment report. You can then present this to the authority yourself.

Do I need to present the assessment report to the driver’s licensing authority?

You are not obliged to present the MPU report to the driver’s licensing authority. If you do not present the assessment report, however, it is very likely that the driver’s licensing authority will turn down your application.

Do I have to prove during the MPU that I do not drink alcohol?

Whether you need to provide evidence for alcohol abstinence, as well as the length of this abstinence, depends on your individual history. You should therefore clarify this before the MPU, with expert support if necessary. Committing a driving offense under the influence of alcohol does not necessarily mean that you have to abstain from alcohol completely. Complete abstinence is necessary, however, if you suffer from an alcohol addiction or you are judged to be unable to control your alcohol consumption. This abstinence must be proven during the MPU through appropriate tests. You can complete a suitable abstinence monitoring program at TÜV Hessen. Click here for more information.

What is the difference between a hair analysis and a urine check?

If you are required to prove abstinence via urine checks, you will be asked to provide multiple urine samples at short notice over the course of the agreement period. We will contact you with no prior announcement, after which you must provide the urine sample within 24 hours. Providing proof of abstinence through a hair analysis allows you to prove your drug or alcohol abstinence retroactively, provided that your hair is long enough. Alcohol abstinence can be proven retroactively over a maximum period of three months (minimum hair length 3 cm). Drug abstinence can be proven retroactively over a maximum period of six months (minimum hair length 6 cm). This means that four hair analyses are required to retroactively prove alcohol abstinence over a period of one year, and two hair analyses for drug abstinence. A combination of hair analyses and urine checks is also possible.

Can I go on holiday while participating in the abstinence monitoring program?

Of course you can go on holiday during your abstinence period. Please inform us of your travel plans so that we can take this into account accordingly. You must inform us of your travel plans (by telephone or email) no later than three days before you are due to begin your holiday.

What if I travel for work, such as working on a site?

Please inform us of your absence no later than three days in advance.

What if I am ill and cannot come to the assessment?

If you are unable to attend the assessment due to foreseeable illness or other health-related reasons (such as a planned operation), please inform us no later than three days before your absence as you would in the event of a holiday or work-related absence. In the event of a sudden illness, you must provide a note from your doctor. This note must include information about the duration of your illness and your inability to travel.

How often can I go on holiday, travel for work purposes or be ill?

We are only able to accept a certain number of “days off” during a contractually agreed abstinence monitoring program. This depends upon the agreed duration of your monitoring program. Please contact your assessment center. Our team will be happy to provide you with information and try to find a solution if there are any problems.

Can my doctor perform the check-ups?

No. Appendix 4a of the German Driver Licensing Act states explicitly that the doctor of the person undergoing a medical-psychological assessment may not perform the assessment.

How much does the abstinence monitoring program cost?

Costs depend on the scope and duration of the monitoring program. Once you know the type and duration of abstinence you must prove, please contact us for more information.

Are external proof of abstinence documents recognized in the MPU?

Yes, provided that they meet the chemical and toxicological examination criteria that apply to all driver aptitude assessment centers. Please clarify prior to the assessment whether the results of your selected provider meet these criteria and can be used in an MPU. With the abstinence monitoring programs from TÜV Hessen, you are certain to be on the safe side. 

Can I prove alcohol abstinence with liver values?

Presenting normal liver values does not provide sufficient proof of alcohol abstinence as abnormal liver values do not always occur with regular alcohol consumption, even at high levels. Liver values can also be influenced by a number of other factors.


Who determines the requirements for a positive assessment?

All officially certified driver aptitude assessment centers, regardless of the provider, base their assessments on the driving ability assessment guidelines issued by the Federal Road Research Insitute, as well as the assessment criteria (3rd edition, issued by the German Traffic Medicine Society (DGVM) and the German Traffic Psychology Society (DGVP)).

Which external results are recognized?

We evaluate all documents and results that you present to us on the day of the MPU. All external results (such as laboratory values, therapy reports, course certificates, etc.) must be signed by the person who performed the corresponding measures (such as the doctor or therapist who treated you, or the course instructor) and must be stamped and dated.

Can my doctor perform the check-ups?

No. Appendix 4a of the German Driver Licensing Act states explicitly that the doctor of the person undergoing a medical-psychological assessment may not perform the assessment.
