31-year-old Kevin McArdle of Longfield, Carrickmacross, was given four years in prison, with the final year suspended, at Monaghan Circuit Court in October 2011 for dangerous driving causing death.
McArdle, who was released last August, has been sent back to prison for a year.
He drove his BMW head-on into a car driven by Stephen Connolly on December 27, 2010.
Mr Connolly’s wife Roisin and their unborn child Catherine were killed. Glen Curtis and Paul Carroll, two 27-year-old friends who were passengers in McArdle’s car, also died.
