THE jury has returned to Warwick District Court after visiting the stretch of Inglewood-Millmerran Rd where Dr Martin Pearson was killed in an alleged hit and run.

Geoffrey Joseph Sleba is accused of striking DrPearson with his prime mover and appeared for day three of his trial yesterday.

The 47-year-old has pleaded not guilty to dangerous operation of a vehicle causing death before leaving the scene.

The court yesterday heard from two of the truck driver's employees and two police officers who attended the scene of the fatal crash, which occurred on Anzac Day 2014 while Dr Pearson was participating in a cycling event.

Darrell Flett testified, saying he spotted a broken spotlight and damaged bullbar on MrSleba's prime mover just days after he allegedly struck Dr Pearson.

"He commented on how my bullbar must be stronger than his because he had hit a kangaroo and it busted his light and bullbar," Mr Flett said.

A Lightforce spotlight lens and lens case were found at the scene of the fatal crash, the same brand as those on Mr Sleba's truck.

Mr Flett said the entire spotlight on Mr Sleba's truck was missing on the passenger side.

When questioned by crown prosecutor Sam Bain, Mr Flett confirmed the other light on the truck was removed a couple of days later and both replaced with a different brand.

Questions of visibility on the stretch of Inglewood- Millmerran Rd were also raised during the third day of proceedings.

Acting Sergeant Matthew Shaw, who attended the crash site, was questioned vigrously by the defence after he claimed to have switched off a red flashing light attached to DrPearson's bike after the crash.

"Were you worried it would run out of battery or something?" Mr Hunter asked.

Defence lawyer Jeff Hunter QC said Sgt Shaw didn't remember the light until he was asked by another officer over two years later.

Sgt Shaw said he turned off the light out of respect for cyclists who had not yet arrived at the scene.

Before switching it off, SgtShaw said he spoke to Senior Constable Shane Ross about the light.

But Sen-Constable Ross said he did not remember the conversation nor the flashing light.

The defence suggested Sen-Constable Ross would remember the light as it was significant for visibility.

"If on arrival you had seen a red bike light flashing, you would not have allowed anyone to touch it and certainly wouldn't have allowed anyone to turn it off," Mr Hunter said.

Mr Hunter said in a suspected vehicle and bicycle crash, visibility and keeping a lookout should have been at the forefront of the officer's mind.

As the first officer on the scene, Snr Sen-Constable Ross said he had a lot on his mind and was focused on preserving the crash site.

"Acting Sgt Shaw is a very competent police officer, you don't tend to watch him," he said.

Proceedings will continue tomorrow.
