A four-year-old girl, Mitzi Rosanna Steady, died when she and her grandmother were hit by the truck. Her grandmother is currently in a crtiical condition in hospital.
Her family issued this statement: "Mitzi Rosanna Steady, aged four, loved and missed by us all."
Three other men aged 59, 52 and 34 from Cwmbran and Swansea, South Wales, were also killed when the truck crushed the car they were in.
It's understood the truck was trying to avoid an accident, when it began careering down the Lansdown Lane hill as parents were picking their children up from school.
The vehicle eventually overturned, after hitting the the four-year-old child and her grandmother, as well as several cars. There are reports that the truck's brakes failed.
The Archdeacon of Bath told Premier: "Obviously there's a great sense of shock and sadness and real grief in the community.
"I was at a special service that the rector hosted this morning at ten o'clock in which the community was invited to gather, we had a full church, my guess is three or four hundred people.
"It was very moving occasion and in the mercy of God it went well, but you can imagine when something unforeseen happens on a beautiful sunny afternoon completely out of the blue like this people's breath has been taken away.
"All the people still in hospital, those who've been bereaved, those are the obvious things [to pray for].
"But I think in any community when something like this happens there's always the question well it could've been me, and there's a kind of hidden shock which becomes apparent."
