Road traffic: Fewer MPUs in Germany – alcohol remains the main reason

The number of mandatory medical-psychological evaluations (MPUs) in Germany has continued its downward trend, with a nearly 7% decrease in 2025 compared to the previous year. These tests, often colloquially referred to as "idiot tests," are designed to assess road safety suitability for individuals who have demonstrated dangerous behavior, such as driving under the influence of alcohol or drugs.

According to the Federal Highway Research Institute (BASt), the total number of MPUs conducted in 2025 fell to 70,135. This decline follows a pattern of decreasing numbers in preceding years. The primary reason cited for requiring an MPU remains conspicuous alcohol consumption, which accounted for 44% of all evaluations. Following closely behind, drug and medication-related issues were the cause for approximately 21% of the tests.

Despite the reduction in the number of evaluations, the outcomes have shown little significant change. In 2025, 58% of individuals assessed were deemed "suitable" to drive, a slight increase from 56% in 2024. Conversely, 38% were classified as "unsuitable," a marginal decrease from 39% the previous year. Around 4% of candidates were recommended to complete an additional training course.

An MPU is typically ordered when the risk of a repeat offense in traffic is considered particularly high, aiming to ensure the safety of all road users by preventing individuals with significant behavioral issues from driving.
