The 42-seater bus was carrying more than 60 people from Ramnagar town to Udhampur city when it hit an auto-rickshaw at a sharp curve in the mountainous region, civil administrator Prem Singh said.
The bus veered off the road and fell down about 100 feet (30 meters) onto the road below, Mr Singh said.
The people on the three-wheeler were also injured, he added.
