ELYRIA, Ohio (AP) _ The state has threatened to revoke the license of a drivers' training school that was investigated after a student driver was involved in a fatal accident in January, officials said Monday.

Ohio Highway Director William M. Denihan notified William E. Keesee, owner of Pro Driving School of Elyria, that he plans to revoke his license as a driver training instructor and the license of the company as a school.

Keesee has 30 days to request a hearing on the state's contention that the school violated three parts of the Commercial Drivers Training School Rules that are part of the Ohio Administrative Code, Highway Safety Department spokeswoman Wendy Schweiger said.

Pro Driving School's attorney, Gerald Smith, said there was no basis for the allegations and said the school would request a hearing.

Michelle Moore, 18, of Elyria was acquitted of a misdemeanor charge of vehicular homicide in September in the Jan. 23 death of Donald Mussey. During her second day of class at Pro Driving School, Ms. Moore, then 17, skidded her car into a car carrying Mussey. An instructor was sitting next to her at the time.

The state notified Keesee of its decision last week after the Ohio Highway Patrol turned up the alleged violations in an investigation of the crash.

''They are the rules which require that beginning drivers shall not be given behind-the-wheel training until after they have had two hours of classroom instruction,'' Ms. Schweiger said.

The school also is accused of violating a rule outlining the subject matter to be covered in theoretical instruction and a record-keeping rule.

The judge who acquitted Ms. Moore said the teen-ager was poorly trained and criticized the school for showing the R-rated, Richard Pryor movie ''Jo Jo Dancer Your Life is Calling'' during the girl's first class. The movie is loosely based on the comedian's life, particularly events following a 1980 incident in which he set himself on fire while smoking cocaine.
