Stadtroda / A4, 21.04.2026 – The Thuringian motorway police have ended a potentially life-threatening drunk driving incident on the A4 near Jena. A truck driver was stopped with 1.8 per mille after attracting attention due to his dangerous driving style.
- When: Monday, April 20, 2026 (midday)
- Where: A4, Autohof Anschlussstelle Stadtroda
- Who: 41-year-old driver of a semi-trailer truck
- Facts: 1.8 per mille breath alcohol, empty alcohol bottles in the cab
- Consequences: Blood sample, 1,000 Euro security deposit, wheel clamp on the truck
Unsafe driving style alerts emergency services
Yesterday at noon, officers from the Federal Office for Logistics and Mobility (BALM) noticed a semi-trailer truck on the Bundesautobahn 4 in the Stadtroda area. The heavy truck was characterized by a clearly unsafe driving style and swerving. The Thuringian motorway police were immediately called in for support to subject the vehicle to an intensive traffic control at the nearby junction – at the local Autohof.
Empty bottles and clear smell of alcohol
The officers’ suspicion was immediately confirmed during the check of the 41-year-old driver. In the cab of the semi-trailer, police found several already emptied alcohol bottles. A breath alcohol test conducted on-site provided a clear but shocking result: the device showed a value of around 1.8 per mille. The driver was thus absolutely unfit to drive and an immense danger to other road users.
Harsh consequences and ban on further travel
After consultation with the responsible public prosecutor’s office, the authorities took consistent action. In addition to the mandatory blood sample, which serves to determine the exact alcohol level for court purposes, the man had to provide a security deposit of 1,000 Euro. To prevent the 41-year-old from continuing his journey in his condition or after insufficient sleep to sober up, the officers used a physical barrier: a wheel clamp was attached to the semi-trailer.
Background: Danger zone A4 and legal consequences
The Autobahn 4 is one of the most important east-west arterial roads in Germany and has an enormously high density of international heavy goods traffic in the section between Hermsdorfer Kreuz, Stadtroda, and Jena. A fully loaded semi-trailer weighs up to 40 tons. If a driver operates such a vehicle under the influence of alcohol, not only is the reaction time drastically increased – accidents often threaten catastrophic consequences for everyone involved due to the enormous kinetic energy.
From a value of 1.1 per mille, “absolute unfitness to drive” (absolute Fahruntüchtigkeit) applies in Germany. This is no longer a mere administrative offense but a criminal offense under § 316 StGB, which usually results in the immediate withdrawal of the driving license. For suspects who do not have a permanent residence in Germany, the public prosecutor’s office often orders a “security deposit” (Sicherheitsleistung). This four-digit sum of money covers the expected fine and the incurred procedural costs and is intended to ensure that the driver does not evade prosecution by leaving the country.
