Long weekend festivities were marred by two serious crashes in the region, including one that killed a man and another that has left a driver fighting for life.
About 10am on Monday, Riverina police were called to Spillway Road, Khancoban after a passer-by found a crashed vehicle.
The 76-year-old driver and sole occupant died at the scene.
"It appeared the driver lost control at a slight bend in the road, and the vehicle struck a tree," Inspector McLay said.
"It looks as though he remained in the vehicle for some time, possibly up to 12 hours, before he was located by a passer-by.
"Police will prepare a coroner's report."
In a separate incident, a man was airlifted from the scene of a single-vehicle crash on private property south-east of Wagga after suffering severe injuries on Saturday.
Inspector Peter McLay said the 38-year-old man had been driving in a Toyota Landcruiser towing a water trailer while completing work on a farm at Yaven Creek.
"The vehicle became unstable and rolled down a hill," he said.
"He became critically injured. He was located some hours later ... and remains in hospital. His next of kin went looking for him and located him in the vehicle."
Inspector McLay urged landowners and workers to be mindful of the dangers.
"You cannot be too careful," he said.
The two incidents occurred as Riverina Police District cracked down on road safety for the long weekend.
"Police conducted over 4800 random breath tests," Inspector McLay said.
"There were more than 231 infringement notices issued to people doing the wrong thing over the weekend.
"Despite police's efforts, there were a couple of nasty crashes."
Inspector McLay said a lot of the infringement notices related to people not wearing seatbelts and speeding.
With the state's long weekend road toll now at six, Assistant Commissioner Michael Corboy, Traffic and Highway Patrol Commander, said it is disappointing people continue to risk theirs and others safety while behind the wheel.
"While most people are doing the right thing, it is frustrating to see people continue to drink and drive or speed, despite our continued appeals," he said.
"It is frustrating for Police to see so many motorists doing the wrong thing when we are doing so much to get the message out to drivers about personal accountability.
"While we will continue to stop those motorists, we need this to be a combined effort with all road users."
