Witnesses tell court of driving concerns

Witnesses have recalled being ''very concerned'' about seeing a blue Mercedes driving on the wrong side of the road on the Midland Highway a year ago.

The hearing against Director of Public Prosecutions, Tim Ellis SC, continued in Hobart this morning and heard from witnesses who were on the highway at the time of the crash that claimed the life of 27-year-old Launceston woman Natalia Pearn.

Mr Ellis has pleaded not guilty to causing death by negligent driving. 

Teacher Jane Bird, who says she was driving behind Mr Ellis, told Magistrate Chris Webster that she became aware of a blue vehicle in front of her.

''The reason I noticed it was that it was moving into the middle lane,'' Ms Bird told the court.

''It stayed smoothly and controlled.''

Ms Bird said she commented to her friend in the passenger seat: ''What on earth is that car doing?'

''As the car approached the sweeping right hand bend we were worried something terrible would happen,'' Ms Bird said.

Elizabeth Murfet, who was in the car with Ms Bird, also told the court: ''I really felt something had happened''.

Defence lawyer Michael O'Farrell questioned the pair about other details of vehicles on the highway at the time and inconsistencies in their police statements from the night of the accident.

Another witness recalled Mr Ellis overtaking her car, and she soon after arrived at the scene of the three-vehicle accident.

''I said, 'Oh my god there's an accident'''.

The trial continues this afternoon.
