The tempo overturned on a road at Jepura village under Savli taluka of the district in the wee hours today. While three persons died on the spot, one succumbed to injuries while being shifted to hospital, District Superintendent of Police (rural) Saurabh Tolumbia told PTI today.
The injured persons were taken to nearby hospitals, police said.
All the occupants of the ill-fated vehicle were labourers, hailing from villages in Vadodara and the neighbouring Panchmahal district.
The mishap took place as the tempo driver apparently lost control over the wheels, Tolumbia said.
