The widow of a cyclist struck and killed on Inglewood-Millmerran Rd has spoken about the day her husband died.

Dr Martin Pearson was killed on Anzac Day in 2014 while participating in a long-distance cycling event.

Truck driver Geoffrey Joseph Sleba, 47, is accused of committing the fatal hit-and-run and fronted Warwick District Court today for the first day of his trial.

He has pleaded not guilty to a charge of dangerous operation of a vehicle causing death before leaving the scene.

Sandra Vigar told the jury of seven women and five men she drove down the same stretch of road as Dr Pearson, as she was assisting in the cycling event.

She last saw her husband at the check-point in Inglewood but he never made it to Millmerran.

"I was expecting to (see him) but I didn't," Ms Vigar said.

"I thought I must have missed him."

She then received a phone call to ask whether she knew where her husband was and when she drove back she saw the emergency vehicles.

Crown prosecutor Sam Bain alleged Sleba was driving dangerously on the road and killed Dr Pearson.

"It was his prime mover, driven by him, (that) collided with Dr Pearson and caused his death," Mr Bain said.

"He continued on after that and left the scene."

Mr Bain said evidence would be presented from a transport counter, located 7.8km from the crash site, which placed Sleba's vehicle on the road at 3.09pm.

The jury heard that if the truck was travelling at 98km/h, it would arrive at the crash site at 3.14pm.

Mr Bain said the GPS on Dr Pearson's bicycle stopped working at 3.14pm.

A spotlight lens was also located at the crash site, Mr Bain said, and the model was the same as those on Sleba's truck, as CCTV footage captured in Brisbane the day before confirmed this.

However Mr Bain said a couple of days after the crash a fellow truck driver noticed the spotlight on Sleba's truck was missing on the passenger side.

Defence lawyer Jeff Hunter said the evidence presented against Sleba was circumstantial and he had no knowledge about the collision.

"There's no direct evidence about the circumstances of the accident," he said.

Mr Hunter said a fellow rider saw a van pull over to the side of the road about 3.30pm and saw the driver get out to look at the front of the vehicle.

"The person got back in the vehicle and drove back across the road and pulled over behind some trees. It's an odd coincidence," he said.

The trial will continue tomorrow.
