The Police said the accident took place late last night along the Monaragala-Wellawaya main road.
The accident involved a lorry and a three-wheeler.
The lorry had reportedly attempted to overtake another vehicle when it crashed into the three-wheeler coming from the opposite direction.
Four people in the three-wheeler sustained injuries in the accident and three of them, including an eight year old child, succumbed to their injuries in hospital. (Colombo Gazette)
