An autonomous bus manufactured by Turkish company Karsan was involved in a collision with a tram on its first day of commercial service in Sweden.

The incident occurred during the self-driving bus's inaugural operations, marking an inauspicious start for the autonomous vehicle pilot program. The collision involved a tram, though specific details about the circumstances of the crash have not been disclosed.

Following the accident, the bus has been taken out of service pending a thorough inspection, according to Patrik Chi, a spokesman for Vasttrafik, the public transport authority operating the service.

The incident highlights ongoing safety concerns surrounding autonomous vehicle technology as cities worldwide experiment with self-driving public transportation systems. Karsan, a Turkish commercial vehicle manufacturer, has been expanding its autonomous bus offerings as part of the growing market for driverless public transit solutions.

The inspection will likely examine both the vehicle's autonomous systems and the circumstances that led to the collision to determine whether technical issues or other factors contributed to the accident.
