A mortage broker fractured a man's skull after ploughing into him with his car.
Gavin Anderson struck William Craig with his silver Mazda yards from Glasgow's Royal Infirmary on March 5, 2018.
The 50-year-old made an illegal U-turn before colliding with Mr Craig who was at a pedestrian crossing.
Mr Craig landed on his head and was treated almost immediately by hospital staff.
Anderson - a first offender - pled guilty yesterday at Glasgow Sheriff Court to causing serious injury by dangerous driving.
The court heard Anderson was driving in the city centre's busy Castle Street around 5.40pm.
Prosecutor Tanjeel Maleque said: "Anderson travelled south in the second lane and passed the right turn filter used to turn on to the A803.
"He turned his vehicle right causing it to cross the northbound marked box and all three lanes.
"He failed to obey the 'no right turn' signs clearly displayed on the traffic lights in front of him and the white arrows on the carriageway.
"Mr Craig was crossing the pedestrian crossing and was about one metre from the footpath.
"Due to Anderson's actions, his vehicle collided with Mr Craig making contact at the vehicle's front panel between the front wheel and nearside passenger door.
"As a result of the collision, Mr Craig struck his head on the ground."
Witnesses who were hospital staff assisted Mr Craig to accident and emergency as police dealt with Anderson.
Mr Maleque said: "The doctor informed police that Mr Craig suffered a fracture to his temporal lobe and superficial abrasions to his head and nose.
"He was required to stay in hospital over three days."
Bobby Reid, defending, told the court Anderson - a dad of three - accepted responsibility for his actions and his remorseful.
The lawyer added: "He owned a company for 20 years and worked in banks before setting it up.
"He was a mortgage broker and coached kids' football for seven years.
"He no longer owns the company.
"His situation was to turn right on the road when clearly he knows he shouldn't have."
Sentence was deferred until next month for background reports by sheriff Gerard Considine.
Anderson, of Bishopbriggs, East Dunbartonshire, was disqualified from driving and granted bail meantime.
