A car hit a broken down electric cart and overturned.
The Dacorum Borough Council-owned cart, which is used to transport sacks of litter, had broken down in Redbourn Road, Hemel Hempstead on Wednesday morning.
Its driver, who was not in the vehicle at the time of the collision, was waiting to be picked up when a green Ford Fiesta hit the cart close to the Sky Ford garage.
Ambulance, police and fire crews were called at 10.20am and the road was closed by officers.
A woman and a girl were taken to Hemel Hempstead’s Urgent Care centre with minor injuries.
