Suspicious driving style alerts motorway police
The risky driving in swerving lines alerted officers on the A4 near Jena on Friday. During the subsequent traffic control, the suspicion that the person at the wheel was under the influence of narcotics was quickly confirmed. Criminal investigation proceedings were immediately initiated against the driver.
To prevent the driver from continuing his dangerous journey and endangering other road users, the emergency services took a decisive measure: the vehicle was fitted with a wheel clamp. This mechanical immobilizer ensures that the car cannot be moved unauthorized or while in a state of intoxication.
Background: Road safety and police measures on the A4
The Autobahn 4 is one of the most important east-west arteries in Thüringen. Especially in the Jena area, which is characterized by high traffic volumes and the complex traffic flow around the Jagdbergtunnel, the motorway police regularly carry out targeted checks. Driving under the influence of drugs or alcohol represents a significant accident risk.
If an acute state of intoxication is detected during a check, officers usually order a blood sample. To avert the acute danger to road traffic, vehicle keys are often seized. The use of a wheel clamp (parking boot) is used in particular when there is a risk that the driver has a second key or if the car is roadworthy but must be parked unattended. This is an effective and robust means of police hazard prevention.
