James Smith, of Augusta, Ga., asked for probation but was turned down by Judge Laurie Yardley, the Lincoln Journal Star said.
"I know you feel remorse," Yardley told Smith, "but you're still not taking responsibility for your actions."
Yardley said Smith had told county probation officers after he'd pleaded no contest and been convicted on Sept. 4 that he didn't need probation or any supervision.
Authorities said Smith's semitrailer turned left in front of a car on Dec. 22 on a westbound ramp onto Interstate 80 in Lincoln. The collision killed 49-year-old college English reading and composition teacher Daniel Everhart and injured his wife, Teri.
Smith repeatedly told officers and then the judge at his sentencing that he hadn't seen the car before his truck crushed it.
Teri Everhart said Monday that she didn't believe Smith.
"We hit the front part of his truck, so he absolutely had to have seen us," she said after the sentencing.
She wanted Smith to be given a longer sentence. The Everharts had planned to move to Canada and live in a cabin after Daniel retired, Teri Everhart said. He also wanted to write a novel, she said.
"He was my everything, and now I don't have him," his wife said. "Now all the plans and stuff we had just aren't going to happen anymore."
