A HEAVILY drugged driver found slumped unconscious over a steering wheel was 'unable to speak' after police eventually roused her.

Nicole Graham was found motionless in her mother's Ford Fiesta at 2.40am.

It came after she had binged on amphetamine at a friend's house, Greenock Sheriff Court was told.

Prosecutor Lindy Scaife said: "A member of the public observed a vehicle parked with both its interior and exterior lights on.

"He repeatedly knocked on the window but failed to wake the accused.

"Concerned because there was no movement, the witness opened the door and smelled what he thought was cannabis.

"He shook the accused and shouted in asking her if she was okay.

"The accused stirred slightly and the witness took the keys from the ignition.

"Police were contacted and an ambulance was also required to attend."

Graham, 28, drove the car sober to her friend's house at Southfield Avenue, Port Glasgow, on January 12 before taking drugs at the property.

She pleaded guilty to a charge of being in charge of the car whilst unfit through drink or drugs.

Her not guilty plea to cannabis possession was accepted.

Fiscal depute Ms Scaife said: "Police saw the accused unresponsive, but they eventually managed to wake her.

"She was unable to speak and was incoherent.

"She staggered and walked in the opposite direction from where the police vehicle was and was unable to answer questions.

"Forensic analysis showed that she had a level of amphetamine in her system."

Defence lawyer Gerry Keenan said: "Whilst in the house she ingested controlled drugs.

"She realised that she couldn't drive and contacted a friend and she stayed in the car.

"She herself felt that she was unable to take the car from the locus."

Sheriff Daniel Kelly banned Graham, of the Port's Dougliehill Terrace, from driving for 18 months and fined her £300.
