Howard Brown has advocated for victims of crime for more than 34 years.
Having dealt with several road trauma matters involving death or serious injury, he says road crime victims are not adequately supported by the NSW criminal justice system.
The victims advocate points to a case where a mother of four was killed after a drunk driver collided with her car during the Queen's Birthday long weekend in 2014.
"All of a sudden, these four kids had to move in with their grandparents," he told AAP on Friday.
"And the cost to them. One of them ended up in jail because he couldn't cope with the loss of his mum."
The government has passed laws that provided trauma support services for families of those injured or killed in a motor accident, provided payments for families who lost unborn babies, and extended access to the Victims Support Scheme for the close family members of victims.
But for many, it's not enough.
The uncertainty and delays that can occur in the courts prolonged the trauma of victims and their families, Mr Brown said.
"I have had victims of motor vehicle accidents say to me, 'There are times where I wish I had died because I wouldn't have to be putting up with the crap I'm putting up with now'," he said.
The question of whether the state's road crime laws are adequately supporting victims of serious road crime and their families will be answered under a new review announced on Friday.
NSW Law Reform Commission will report on whether new offences or legislation are required to better support victims and their families.
"The trauma and damage caused by road crime deaths have consequences that extend far beyond the initial incident; they have a devastating impact on individuals, their families and the broader community," Attorney-General Mark Speakman said.
While Mr Brown is broadly supportive of the review, he says the government needs to act on the results immediately once they receive them.
The review will ensure the justice system can effectively respond to road crimes and remind the community to think twice before putting another life in danger, Roads Minister Natalie Ward said.
As of Thursday, 252 people had died on NSW roads this year. In the year to March, 9338 people were hospitalised due to road trauma.
