A significant traffic incident took place this morning at Glaskartunnelen in Bergen, Norway, involving a bus and three passenger vehicles. The accident was reported by the fire department at 08:59 and was attributed to a lane change maneuver by the bus, during which one of the cars made contact with it. This initial collision resulted in severe braking, leading to further participation from other vehicles in the vicinity. The police operations manager, Bjarte Rebnord from Vest police district, indicated that one of the cars suffered substantial material damage, although no injuries have been reported at this stage. Emergency services, including ambulances, promptly arrived on the scene to handle the situation, and it has been confirmed that all individuals were able to exit their vehicles safely. As a precautionary measure, the tunnel was closed in the southbound direction while authorities manage the aftermath of the collision and clear the vehicles involved. The incident underscores the potential hazards associated with lane changes in busy traffic conditions, and it is a reminder for drivers to exercise caution on the roads.
