Preliminary investigations into the crash that claimed the life of a 30-year-old Wagga man on Wednesday suggest the night's heavy rain did not contribute.
The collision claimed the life of a 30-year-old Wagga man who was driving westward in a Mitsubishi Outlander shortly before 7:30pm.
"For reasons unknown just as he's entered the 100[km/h] area, he's crossed to the wrong side of the road, by the looks of the scene, and travelled into the path of an on-coming Kenworth prime mover that was heading in an easterly direction," Wagga Inspector John Aichinger said.
"It's obviously a very traumatic time for the family and friends of that young man, and I can assure you that it was also a very traumatic incident for the police who attended."
The truck driver, a 47-year-old man, was transported to Wagga Base Hospital for mandatory testing. He has now been released from hospital.
"He is co-operating with police and there's been no issues with that driver," Inspector Aichinger said.
Previous reports indicated that a third vehicle was involved in the accident, but police now confirm the crash occurred between the two.
A third driver stopped to provide police with a witness statement.
The section of highway was re-opened at 3.30 on Thursday morning, at which time NSW Traffic Incident Response distributed temporary speed limit signs around the affected areas.
Owing to debris and mud left on the ground, the speed limit in the area has now been reduced to 60km/h.
Police will continue to investigate the circumstance and will prepare a report for the coroner.
