Tragic Accident in Kerenzerberg Tunnel: Driver Killed After Breakdown
On the morning of Monday, August 10, 2026, a fatal accident occurred in the Kerenzerberg Tunnel on the A3 motorway near Filzbach in the canton of Glarus, Switzerland. The incident happened at approximately 9:17 AM when a driver, who had stopped due to a vehicle breakdown, was struck and killed by a truck. According to initial reports, the driver had been traveling in the direction of Chur on the normal lane when his car experienced a mechanical issue, prompting him to exit the vehicle.
The collision resulted in immediate closure of the tunnel, causing significant traffic disruptions in the Walensee region. Authorities announced that the tunnel would remain closed until Tuesday morning to allow for a thorough investigation and cleanup. Emergency services, including police, fire brigade, and medical teams, responded swiftly, but unfortunately, the driver succumbed to his injuries at the scene. The truck driver involved was unharmed but is receiving psychological support.
This tragic event highlights the critical importance of road safety, especially in tunnels. Experts emphasize that in the event of a breakdown, drivers should remain inside their vehicles with hazard lights on and call for emergency assistance immediately. Exiting the vehicle on a motorway, particularly in a tunnel, poses extreme risks due to limited visibility and high-speed traffic. The authorities are currently investigating the exact circumstances leading to the accident, including the sequence of events before the driver left his car.
As the community mourns this loss, the incident serves as a stark reminder of the potential dangers on Swiss roads. The A3 motorway is a vital artery for both commuters and freight transport, and this closure has led to long queues and diversions. Local authorities have urged drivers to plan alternative routes and to exercise patience during the ongoing investigation. Our thoughts are with the victim’s family and friends during this difficult time.
