Rogel Aguilera-Mederos, 26, was convicted in October of vehicular homicide and other charges stemming from the April 25, 2019, crash on Interstate 70, just west of Denver.
A jury convicted Aguilera-Mederos of four counts of vehicular homicide, six counts of first-degree assault, 10 counts of attempted first-degree assault, four counts of careless driving causing death, two counts of vehicular assault and one count of reckless driving.
Aguilera-Mederos, who was hauling lumber, was traveling at least 85 mph on a part of the interstate where commercial vehicles are limited to 45 mph because of a steep descent from the Rocky Mountain foothills, according to investigators.

The initial impact caused a 28-vehicle chain-reaction wreck, which ruptured gas tanks, causing a giant fireball to erupt with flames that consumed several vehicles and melted parts of the highway.
He testified that the brakes on his semitrailer failed before he plowed into vehicles that had slowed because of another wreck in the Denver suburb of Lakewood.
But prosecutors argued he could have used one of several runaway ramps as his truck barreled down from the mountains. Police said that just before the crash, the truck traveled past a ramp on the side of the interstate that is designed to safely stop trucks and other vehicles that have lost their brakes.
The crash killed Miguel Angel Lamas Arellano, 24; William Bailey, 67; Doyle Harrison, 61; and Stanley Politano, 69.
Aguilera-Mederos wept as he spoke during the sentencing, apologizing to the families of the victims and asking for their forgiveness.
"I am not a criminal," he said. "I am not a murderer. I am not a killer. When I look at my charges, we are talking about a murderer, which is not me. I have never thought about hurting anybody in my entire life."
District Court Judge Bruce Jones imposed the sentence after finding it was the mandatory minimum term set forth under state law, The Denver Post reported.
"I will state that if I had the discretion, it would not be my sentence," the judge said.
