Mt. Jackson, Va. (WHSV) -- Virginia State Police ruled that 62-year-old Delmar Lee Oscar's death was an accident.
An employee at a Liberty truck stop said he pulled in like he did two to three times a day, but Wednesday it was different.
Police said Oscar's body was found laying beneath a 2005 Mack truck after he got underneath it to do some repairs.
Lisa Lucas who is a cashier at the truck stop said she saw the man nicknamed "Ducky" on Wednesday shortly before it happened.
"We were told that his brake lines froze on his truck, so he pulled off to try to unfreeze them and somehow the truck brakes didn't lock to where it would keep it from rolling backwards and it rolled on top of him," said Lucas.
Oscar died at the scene. His body wasn't noticed for hours.
"He wasn't answering the phone for either his daughter or his wife," said Lucas.
That's when his wife began panicking.
"She called the company that he works for, because he hadn't come home yet and normally he's home by a certain time everyday," said Lucas.
It's an accident one truck driver says others should try to avoid this time of year when brakes often freeze
"My truck weighs 17,500 pounds and if that rolls over on top of you it's going to kill you," said Chris Whitaker, who is a truck driver.
"Stay out from under the vehicle completely, if you have to call, even if it cost money. You have to call somebody to come fix them. It's better than losing your life," said Whitaker.
Many who knew Oscar described him as a nice man.
