Shane Anthony Mayne, 27, intentionally chased down and killed 19-year-old student Matthew Gouldthorpe in February last year.
The teenager had arrived in the State three days earlier to study at university and had asked the pair for directions back to his lodgings at 3.30am on February 19.
Mayne and his passenger, Michael John Brown, 24, were both charged with murder.
Prosecutors allege that Mr Brown instigated the crime by telling Mayne to run over Mr Gouldthorpe.
Mayne pleaded guilty but Mr Brown pleaded not guilty and is on trial in the Launceston Supreme Court. Mayne drove on to the footpath in Dowling St and clipped Mr Gouldthorpe.
The teenager attempted to flee before Mayne turned and drove at him at up to 83kmh.
Mr Gouldthorpe was dragged under the car and died at the scene from multiple head and internal injuries.
On Tuesday, Mayne gave evidence that Mr Brown had never told him to run over the teenager and he could not remember telling police that he had.
Yesterday, the court was played three interviews filmed on the day of the murder, where Mayne told police that Mr Brown had instigated the crime.
“I was told to hit him so I hit him,” Mayne told accident investigators Sgt Mike Davis and Const. Peter McCarron at 8.10am.
Mayne, who was crying and often unintelligible, walked Sgt Davis and Const. McCarron through the scene at 8.45am.
“The bloke I was in the car with said `hit him’ – I started laughing, thinking he was joking around,” Mayne sobbed.
Mayne said he was going to drive away after mounting the footpath but Mr Brown told him again to hit Mr Gouldthorpe.
In cross-examination from defence lawyer Greg Richardson, Sgt Davis said Mayne had lied in his first interview and said Mr Brown was the driver.
He admitted that he was the driver in his second interview.
Mayne told detectives in a fourth interview that Mr Brown seemed serious when he said to hit Mr Gouldthorpe.
“I said `are you fair dinkum?’ and he said `yep’ so I did,” Mayne said.
“He was laughing at that time but as soon as I hit him he was like, `F—, why did you do that?’ I said, `You told me to hit him so I hit him’.”
The court will hear closing submissions from prosecution and defence today before Justice Ewan Crawford sums up the case.
The jury was told it would not retire to consider its verdict until Monday morning.
