Driverless PostBus Hits Swiss Bank in Nunningen

A driverless public transport bus operated by PostBus Switzerland crashed into a bank building in Nunningen on Thursday evening, causing significant property damage but no injuries.

According to the cantonal police, the articulated autonomous bus began rolling for reasons that are still under investigation at around 8:35 pm while it was stationary at a stop on Zullwilerstrasse.

The vehicle crossed a traffic island before colliding directly with the façade of a local bank branch. Authorities confirmed that both the building and the bus sustained considerable damage in the impact.

Emergency services responded quickly to the scene, but no passengers or bystanders were injured in the incident.

Police in Switzerland have launched an investigation to determine what caused the driverless vehicle to move unexpectedly. Technical failure, system malfunction, or braking issues have not been ruled out at this stage.

Driverless and semi-autonomous public transport systems have been increasingly tested across Switzerland and Europe as part of efforts to modernise urban mobility and improve efficiency. However, the incident highlights ongoing safety challenges associated with autonomous transport technologies.

Authorities have not yet confirmed whether the bus was in fully autonomous mode at the time of the accident or whether a remote operator was monitoring the system.

The investigation is ongoing, and further technical assessments are expected in the coming days.
