A driver was distracted by a wrestling DVD playing in his ute when he slammed into another car on a South Australian highway, killing an elderly man, a court has heard.
Mitchell Deane Franklin has gone on trial in the SA District Court accused of dangerous driving causing the death of 86-year-old Harvie Spencer in the crash near Port Pirie in June 2013.
The 28-year-old smashed squarely into the back of Mr Spencer's car, killing the older man instantly, the court heard on Monday.
Prosecutors allege Franklin had ample time to see the other car, which was stopped at an intersection on the Augusta Highway, but he did not veer or slow down.
"How did that happen?" prosecutor Michael Foundas said in his opening, before answering his own question.
"Installed in the centre console of the car was a DVD player that was on and operating, playing a wrestling DVD.
"The accused drove his vehicle into the rear of Mr Spencer's vehicle because he was not keeping a proper lookout on the road."
The prosecutor said Franklin was most likely watching the WWE SmackDown DVD at at the time of the crash but only had to prove that the security guard, from suburban Andrews Farm, was driving dangerously.
Franklin was travelling at least 85km/h and would have had more than 10 seconds to see Mr Spencer's car after coming around a bend in the highway, Mr Foundas said.
"There is simply no justifiable reason why the accused didn't see the car," he told the jury.
Franklin is also charged with driving with a TV receiver operating, and dangerous driving causing harm to his passenger whose jaw was broken in the crash.
The jury will travel to the site of the crash during the trial and hear from police as well as several witnesses.
