Two men have pleaded guilty to causing death by careless driving after they crashed into a pensioner while allegedly racing each other.
Richard Williams, 22, from Ammanford, Carmarthenshire, and Rhydian Griffiths, 20, of Carmarthen, had denied causing death by dangerous driving.
Swansea Crown Court heard that the pair drove at up to 100mph on a dual carriageway in Carmarthenshire.
Colin James, 66, died minutes after the crash on the A48 in April 2009.
The court heard the fatal crash, between Cross Hands and Pont Abraham, happened less than 24 hours after Williams had been stopped by police.
On that occasion Williams was driving a different car and was found to be twice the drink-drink drive limit. He was also uninsured.
Both had denied the more serious charge of causing death by dangerous driving.
On Friday, they were read the lesser charges of causing death by careless driving, and pleaded guilty.
Rhydian Griffiths, from Nantycaws, near Carmarthen, was driving a modified Seat Ibiza with his heavily-pregnant teenage girlfriend and a relative in the car.
Williams was alone in a Renault Clio.
Father-of-two Mr James was struck first by Griffiths' car and was sent spinning into the path of Williams' vehicle, the court heard.
James Jenkins, prosecuting, said expert evidence made it unclear "whether or not the collision might have occurred if the defendants were travelling at lesser speed".
Sentencing has been adjourned until the first week of November. Both men were released on conditional bail.
