Bavarian police say a particle filter in the exhaust system caught fire at about 5 a.m. Monday due to a technical defect.
They say the driver reacted quickly and got the bus to the side of the highway and put the fire out with an extinguisher before authorities arrived at the scene. Police say eight musicians were aboard but Pink herself was not.
The band played a concert in Munich on Saturday and was on its way to Berlin for a show Tuesday night. The musicians were able to continue on their journey on a replacement bus.
