Vic road rage driver jailed over death

A former banker who abused a mother after he caused a car crash that killed her little boy has been branded arrogant, selfish and dangerous by the judge who jailed him.

Victorian County Court Judge Geoffrey Chettle put Ian Bouch, 48, behind bars for eight and a half years, with a minimum of six to serve, saying there was a clear need to protect the community from him.

Bouch has previous road rage convictions that Judge Chettle said demonstrate his sense of entitlement when he's driving.

"The consequences of your crimes are just horrific," he told Bouch, who was found guilty by a jury of culpable driving and negligently causing serious injury.

Anisa Rage had her four children in her van as she drove on Hopkins Road, Truganina, where Bouch's Audi sped up behind her on May 27, 2014.

The father of two was angered by her slow pace and flashed his lights and honked his horn.

After tailgating her, he overtook her, positioned himself in front, stuck up both of his middle fingers then jammed on his brakes.

Bouch knew there was a truck behind her van.

Ms Rage was forced to stop but the truck driver could not prevent his vehicle from hitting the van.

One child, Yahye Hashi, 10, was fatally injured, and his sister Yasmine's arm was broken.

Bouch's car was also struck, and he immediately began hurling blame and abuse at the two other drivers.

He falsely claimed Ms Rage was on her phone.

In a victim impact statement, Ms Rage said through the horror of the day, what continues to flash through her mind is Bouch's behaviour.

"What decent human would utter such disgraceful words with a 10-year-old boy lying unconscious on the ground, his body fitting?" she wrote.

"He was so unhelpful, so cold, so unsympathetic."

In sentencing on Tuesday, Judge Chettle said Bouch's conduct was "discreditable".

Yahye was flown to the Royal Children's Hospital where he died on June 1.

Outside court, Leading Senior Constable Cameron Merrett said on behalf of the family that there was no sentence that would ever be sufficient.

"All that they would have hoped for is that he (Yahye) walk back through their door, smile, wave and laugh and just say that he was home," Sen Const Merrett said.

Bouch has been banned from driving for 10 years.
