A man injured his lover's spine after crashing his motor into a barrier.
Brandon Nobre, 23, initially collided with another car causing both to spin out of control on Glasgow's M8.
Nobre had been travelling up to 100 miles per hour and overtook two cars before the horror smash.
His passengers - partner Piper O'Neill and friend Thomas Begbie - suffered injuries as a result.
The driver of the other car, Nicolas Pelc sustained a bruised Tibia.
Nobre escaped with minor bruising.
He pled guilty today at Glasgow Sheriff Court to causing serious injury to Miss O'Neill by dangerous driving.
The court heard that Nobre was behind the wheel of a blue Volkswagen on the motorway near Townhead.
Nobre overtook the first vehicle whose driver believed that he was going up to 100 miles per hour in the 40 zone.
A taxi driver who was also overtaken at speed claimed he got a "fright."
Nobre went on to undertake a third vehicle at speed.
Mr Pelc meanwhile was driving a Ford Transit van as Nobre attempted to change lanes.
Prosecutor Sean Docherty said: "He collided with the rear offside of the van causing both vehicles to spin into the central Armco barrier causing extensive damage to both vehicles."
Mr Begbie and Miss O'Neill emerged from the car while Nobre was found inside appearing "stunned."
He later told witnesses that he believed he was travelling at 80 miles per hour.
Mr Palc meanwhile was cut out of his van by medics while suffering from tibia and back pain.
Mr Begbie and Miss O'Neill were also taken to hospital.
Mr Docherty said: "It was noted that Miss O'Neill sustained a fracture of her vertebrae within her spin.
"The estimated recovery time is one year.
"Mr Palc suffered a bruised tibia while Mr Begbie and Nobre suffered minor bruising."
Sentence was deferred pending background reports until next month by Sheriff Gerard Considine.
Nobre, of Durham, was disqualified from driving in the interim period.
