The mishap took place in the afternoon while the jeep was on its way to Pauri, Pauri Superintendent of Police Ajay Joshi said.
Four persons were killed on the spot, while the injured victims were admitted to a hospital at Patisain, he said.
Prima facie, it appears that the mishap was caused due to the driver's negligence who got down from the vehicle to load more passengers while its engine was still on, he said.
Rescue teams recovered the bodies with the help of locals, he said.
