Driver severely injured after car overturns on Autobahn 81 in Hilzingen
A 52-year-old motorist was taken to a hospital after his car overturned multiple times during a lane change near the Hohentwieltunnel, closing the motorway toward Hegau for four hours.
Sequence of the rollover collision
A 52-year-old driver sustained severe injuries in a vehicle rollover collision on Autobahn 81 in southern Germany on the evening of 6 September 2026. The incident occurred within the municipal territory of Hilzingen, located in the administrative district of Konstanz in the state of Baden-Wuerttemberg. According to police, the motorist was traveling along the motorway corridor and attempted to perform a lane change. During the maneuver, the vehicle abruptly departed from the designated driving lane and veered completely off the road surface. The underlying cause of the sudden deviation remains unexplained, with investigators noting no initial determination for why control was lost. After exiting the carriageway, the car overturned multiple times along the roadside before coming to a standstill resting on its roof.
Medical transport and emergency operations
Emergency rescue units, police patrols, and medical personnel were dispatched to the collision location situated between the Hilzingen junction and the north portal of the Hohentwieltunnel. First responders provided urgent medical stabilization to the 52-year-old driver directly at the scene to address his severe physical injuries. Following on-site care, ambulance personnel transported the motorist to a hospital for continued clinical treatment and evaluation. Police officials confirmed that no other occupants were inside the car during the multi-revolution rollover and that no adjacent vehicles travelling along the motorway were impacted or involved in the collision.
Traffic closure toward Hegau junction
The collision necessitated emergency operations and recovery procedures along the Autobahn 81 section leading toward the Hegau motorway junction (Autobahnkreuz Hegau). To safeguard emergency responders, secure the overturned vehicle, and facilitate salvage efforts, police instituted a complete closure of the directional carriageway. The entire highway stretch connecting the Hilzingen exit to the Hohentwieltunnel entrance was cordoned off to all approaching vehicular traffic. Specialist recovery vehicles and towing equipment were deployed onto the scene to right the inverted vehicle, extract it from the road embankment, and remove the heavily damaged car from the highway perimeter.
