MPU (medical-psychological examination)
Führerscheinstelle · Driver fitness
The medical-psychological examination (MPU) — colloquially the “idiot test” — is neither a penalty nor an official act of the authority, but a driver fitness assessment report. The driving licence authority orders it under § 11 Abs. 3 of the Driving Licence Ordinance (Fahrerlaubnis-Verordnung, FeV) if specific facts give rise to doubts as to whether you are fit to drive motor vehicles. The report is not prepared by the authority, but by an officially recognised assessment centre for driver fitness — such as TÜV, DEKRA, GTÜ, AVUS or pima-mpu. Only on this basis does the driving licence office (Führerscheinstelle) decide on withdrawal, refusal or reissue of the driving licence.
Which legal basis the order relies on determines the entire further process. For alcohol, § 13 FeV applies — in particular at a blood alcohol concentration of 1.6 per mille or more or a breath alcohol concentration of 0.8 mg/l or more, but also in cases of alcohol abuse, repeated violations or a previous withdrawal. For cannabis, the separate § 13a FeV (“clarifying doubts about fitness in cannabis-related cases”) has applied since the 2024 reform, and for other narcotics and psychoactive medicinal products, § 14 FeV applies. Anyone who reaches eight or more points in the Register of Driver Fitness (Fahreignungsregister, FAER) loses their driving licence under § 4 Abs. 5 of the Road Traffic Act (Straßenverkehrsgesetz, StVG); for reissue, the authority generally orders an assessment report under § 4 Abs. 10 StVG.
One particularly stubborn misconception concerns the cost: the MPU has no official fee. The former fee item in the Fee Schedule for Measures in Road Traffic (GebOSt, Nummer 451 ff.) was abolished on 1 August 2018. Since then, the recognised assessment centres set their own prices; figures such as “€350 to €750” come from the old fee schedule and are well below what is actually charged in 2026. Depending on the question at issue and the provider, a realistic figure is around €550 to €1,000, plus abstinence tests and preparation. To put the chances of success in context: according to the figures from the Federal Highway and Transport Research Institute (BASt), a total of 75,257 assessments were carried out in 2024, of which just under 57% were rated “fit”, just over 39% “not fit” and just over 4% ended with a course recommendation.
