Four women died in a Flixbus accident on the A9 at the end of March 2024. The exact cause of the accident is still being investigated.

30 people were injured in the accident, the cause is still unclear and remains under investigation. Passengers are talking about a driver dispute. Flix bus boss André Schwämmlein spoke to the Funke media group about the incident. He said: “One immediately thinks of the victims of this tragic accident. It’s a shock for us, the whole team and for me personally," he said in the interview with the Morning Post. He also said that seat belt requirements had to be adhered to much more consistently: ‘The bus drivers also point out that seat belts are required. We appeal to all passengers to buckle up.’ He also noted that the Flix Bus vehicles are only five years old on average, meaning inspections are largely unnecessary. He could rule out that driving and rest times were ignored, and “the bus was in good condition”
