A verdict of death by misadventure was recorded on the Durham University student after a 17-day inquest last year.
Coroner John Sleight-holme heard there were faults on the ride that disabled safety devices designed to ensure two cars were never on the same section of track together.
Now the Health and Safety Executive is to prosecute Lightwater Valley Att-ractions Ltd, one of its maintenance electricians, Eric Butters, and the French manufacturer of the spinning fairground ride.
Miss Savage, of Wath-on-Dearne, near Rotherham, died in Leeds General Infirmary the day after suffering head and spinal injuries when cars on the ride collided in June, 2001.
The owner of the theme park at North Stainley, near Ripon, Mr Butters and Societe Reverchon Industries France, of Paris, all face charges under the Health and Safety at Work Act.
Lightwater Valley Attractions Ltd is charged with failing to conduct its undertaking in such a way as to ensure, so far as reasonably practicable, that persons not in its employment were not exposed to risks to their health and safety.
Eric Butters, of Harrogate, is accused of failing to take reasonable care to ensure the health and safety of persons who might be affected by his acts or omissions at work.
The French firm is charged with supplying fair-ground equipment without ensuring, so far as reasonably practicable, that it was designed and constructed to be safe at all times.
Mr Butters was the Lightwater Valley employee called to deal with the situation when one of the cars failed to climb an incline and became trapped on a roll-back arrester nearly 40ft from the ground.
Miss Savage and her friend Joseph Shimmin – due to get their second year biomedical science examination results the next day – were riding in a car which stopped on a safety brake.
She died and three other riders were injured when a third car rolled into a dip, colliding at an impact speed of around 45mph with the car in which she was sitting.
The charges are due to be heard at Harrogate Magistrates Court on Friday, November 18, but it is possible the case may be sent to York Crown Court. In the magistrates court there is a maximum penalty of £20,000 on each charge. In a Crown Court the maximum is an unlimited fine.
