Two separate multi-vehicle collisions involving four cars occurred in Switzerland within a week of each other.

On October 20, a four-car accident in Weissenbach, Boltigen, resulted in five injuries after a vehicle drifted into oncoming traffic. Emergency responders, including a Rega helicopter, transported the injured to the hospital, and the Bern Cantonal Police initiated an investigation.

On October 26, a similar four-car pileup occurred on the A12 motorway between Matran and Fribourg-Sud. This incident left seven people injured. Preliminary findings suggest the crash began when a vehicle entered the motorway from the emergency lane; the driver of that vehicle fled the scene. The Fribourg Cantonal Police are investigating the circumstances, noting that emergency response efforts were delayed because motorists failed to form a rescue lane.
