Police are appealing for witnesses, information and dash cam footage following a serious road traffic collision on the A41.
The incident occurred at around 10.10am yesterday (Monday 21 August) on the southbound carriageway between Hemel Hempstead and Kings Langley.
It is believed up to six vehicles were involved in the incident, including a white Mercedes tipper HGV and a black Peugeot.
The three occupants of the Peugeot were taken to hospital. A man and a child, whose injuries are not described as life-changing or life-threatening, were taken to hospital by road.
A woman, meanwhile, was airlifted to hospital with potentially life-changing injuries.
Sergeant Alex Ward, from the Road Policing Unit, said: “Our enquiries are continuing, and we are appealing for any witnesses to please come forward.
“If you were driving in the area and have a dash-cam fitted, please check it as you may have recorded some crucial footage to assist our investigation.
“I would also like to thank the public’s patience as the road remained closed for several hours while our officers carried out crucial work at the scene.”
