A TEENAGER died after he lost control of his car and crashed on a main Huddersfield road.
Several people saw the tragedy unfold on Bradford Road in Fartown late on Saturday night.
But police have urged anyone else who saw the crash or the red Honda Civic just before the accident to come forward.
The smash happened on the left-hand bend at the junction with Allison Drive at 11.10pm. The car may have been in Huddersfield town centre before the teenager drove it along Bradford Road towards Fixby.
He has not yet been named by police.
Insp Nick Dyson said: "The driver lost control on a left-hand bend and the car crashed into a lamp-post, ending up on its roof. Unfortunately, the driver died at the scene."
Several people who were walking nearby tried to revive the driver, but he died soon after para-medics arrived.
Police closed the road for several hours while the crash was investigated.
Sub-Officer Lee Benson, of Huddersfield fire station, said: "The paramedics were there when we arrived, but unfortunately the man had died.
"The car crashed into a lamp-post and smashed against railings at the side of the road."
Mr Khanny Mansaf, who is building a house at the junction of Bradford Road and Allison Drive, said the speed limit had been reduced to 30mph while roadworks were carried out recently.
He added: "The road had been really quiet, but the limit has been increased to 40mph. There has been a big difference, with some cars being driven at 70mph."
