A suspect was dragged from a car by police following a high-speed pursuit in Honley.
It is believed the chase began in Newsome and involved a silver Hyundai 4x4.
Witnesses said the Hyundai was pursued by police cars along Woodhead Road towards Holmfirth.
The chase ended when the speeding suspect vehicle struck a Ford people carrier at the junction.
A spokesman for West Yorkshire Police said the Hyundai involved was being followed by police, but was not part of an official police pursuit.
It is thought police dragged the suspect from the vehicle after he locked himself in.
The suspect was laid in the road and checked over by a paramedic before he was led into the ambulance in handcuffs.
An elderly couple in the Ford were also taken to hospital, although it is not thought their injuries were serious.
The chase is thought to have started at around 10.30am.
Witnesses reported hearing a loud bang as the pursuit came to a sudden end.
One witness said: "He'd gone at full speed on Woodhead Road and was on two wheels.
