The injured, all aged between 25-30 years, were rushed to Phagwara civil hospital.
The pile-up took place due to poor visibility owing to a thick blanket of fog when the teachers were coming to nearby Kamla Nehru Public School at Chak Hakeem village, police said.
The 11 injured includes nine female teachers, a male teacher, and the driver of the school bus, police said.
