THC-positive: Driver stopped in Friedrichshafen
Early on Friday morning, officers from the Friedrichshafen police station stopped a 20-year-old motorist who was allegedly under the influence of narcotics. The check took place on Ailinger Strasse in the Lake Constance district. After the patrol noted drug-typical signs, a preliminary test came back positive for the cannabis active substance THC. The young man then had to provide a blood sample in hospital and was not allowed to continue his journey. According to police, he faces a substantial fine and a driving ban.
Stop on Ailinger Strasse
Ailinger Strasse is one of the inner-city traffic routes in Friedrichshafen on Lake Constance. There the patrol stopped the 20-year-old in the early morning hours. Officers registered signs in the driver that they classified as typical of drug use. Police did not name individual symptoms in this case, but made clear that the impression on the spot was enough to offer a drug preliminary test. The test reacted positively to tetrahydrocannabinol, or THC. That provided an initial indication of possible cannabis use.
A preliminary test does not replace a laboratory analysis. It serves police as guidance on whether a blood draw and further measures are justified. In this case, exactly that next step followed. Until the blood sample is evaluated, the allegation remains presumed, as the statement from Ravensburg Police Headquarters emphasises. The authority did not name the person concerned.
Blood sample instead of continuing the journey
The 20-year-old was taken to a hospital, where a blood sample was taken. That sample is the central piece of evidence in administrative-offence and criminal proceedings. Only the laboratory analysis shows what concentration of the active substance was present in the blood serum. Police prohibited the driver from continuing his journey. The aim was to prevent him from remaining behind the wheel as long as impairment could not be ruled out. Whether the vehicle was towed, seized or handed over to another person is not stated in the report.
On the current assessment, the man must expect a substantial fine and a driving ban. Both are typical consequences when driving under the influence of cannabis is proven. The exact amount of the fine and the length of a driving ban depend on the test result, possible prior entries and the authority's overall assessment. The current press release gives no figures on this.
THC in road traffic
Cannabis is legalised in Germany under certain conditions. Road traffic, however, is subject to its own, much stricter rules. Anyone driving a motor vehicle must be able to control it safely. THC can impair perception, reaction time and attention. Driving under the influence of the substance therefore remains relevant under fine and driving-licence law, regardless of whether the consumption itself was permitted.
Since August 2024, a statutory limit of 3.5 nanograms per millilitre has applied to THC in blood serum. Mixed use with alcohol is assessed more strictly. Novice drivers and young drivers are also subject to additional duties of care. The motorist who was stopped is 20 years old; whether special probation-period rules apply to him cannot be inferred from the report. A positive preliminary test also does not automatically mean that the limit was exceeded. Only the blood analysis clarifies whether an administrative offence or further allegations are at issue.
How a drug check proceeds
Traffic stops involving narcotics follow a fixed pattern. Officers first observe driving style, eye contact and behaviour at the wheel. If signs appear, a standardised preliminary test may follow. If it is positive, a blood draw is usually ordered. In parallel, the person concerned is often prohibited from continuing the journey.
- Observation of drug-typical signs by the patrol on Ailinger Strasse
- Conduct of a preliminary test with a positive finding for the active substance THC
- Blood draw in hospital for laboratory analysis
- Prohibition on continuing the journey and possible fine-law consequences
Operation in the Lake Constance district
Friedrichshafen lies in the Lake Constance district in Baden-Württemberg. Ravensburg Police Headquarters is responsible for the press release, publishing reports from the district in bundled form. The actual check was carried out by a patrol from the Friedrichshafen station. Ailinger Strasse runs through the urban area as an inner-city state road and regularly carries commuter and through traffic.
The headquarters' collected bulletin that day also contained further incidents from Überlingen with no connection to narcotics. For classifying the present case, only the incident in Friedrichshafen is decisive. It is a traffic stop with a drug connection, not a raid, a trafficking investigation or the seizure of larger quantities. Even so, the incident falls within narcotics crime in the broader sense, because the suspicion of driving under the influence of THC is at the centre.
Consequences for the driver
If the blood sample confirms a relevant THC value, points in Flensburg and measures by the driving-licence authority may follow in addition to a fine and a driving ban. At higher values or in the event of repeated offences, a medical-psychological assessment may be ordered. Whether any of these steps will apply to the 20-year-old will only be decided after the analysis.
For queries, Ravensburg Police Headquarters refers to its public-relations unit. The contact is Luca Bosch. In the statement, the authority stresses the alleged nature of the accusation. Until the laboratory values are available, it remains open which specific legal consequence will follow. On the current facts, only this is established: the preliminary test was positive for THC, the journey was ended, and the young driver must expect noticeable consequences.
