A court has heard how a wedding trip ended in tragedy when a man lost his life on a south of Scotland motorway.
The incident happened on the A74(M) near Johnstone Bridge service station in Dumfries and Galloway in July.
Van driver James Rai, 41, denies causing the death of Raju Singh, 28, from Tyne and Wear, by driving while banned and without insurance.
The trial before Sheriff George Jamieson at Dumfries Sheriff Court continues.
Mr Singh's brother-in-law told the court he was driving family members from a wedding in Glasgow back to their home in Washington, in Tyne and Wear, when an argument started.
He had pulled into the service station to try to calm Mr Singh, and another relative who had fallen out.
However, he said the argument escalated and his brother-in-law had stormed off and disappeared.
When they phoned him he said he was on the hard shoulder of the motorway walking home.
In the dock, Mr Rai denied being responsible for Mr Singh's death.
A man who was his passenger on the night told the court they went into the service station to check the price of diesel.
When they pulled back onto the motorway there was a bump and the windscreen shattered.
He said they thought they had hit a deer or something similar.
