A 20-year-old Northern Ireland man has appeared in court the Republic of Ireland charged with causing the deaths of three people by dangerous driving.
Keith Lennon, of Forest Park in Dromintee, County Armagh, is also accused of failing to report the crash.
It happened on the N1 in County Louth at about 02:15 local time on Saturday.
Mother and son Mary and Kevin Faxton, from Bessbrook, County Armagh and Bryan Magill, from Newry, County Down, were killed in the collision.
In court in Dundalk on Monday a bail application was refused due to the serious nature of the charges, the nature of the evidence and because the judge believed the accused posed a flight risk.
Mr Lennon was remanded in custody to Cloverhill Prison in Dublin.
He is due to appear in court again this week.
