OREM — A 34-year-old motorcyclist killed Wednesday in a collision with a semitrailer truck was a devoted family man, friends say.

Just after 8 a.m., Orem native David Glen Lant was traveling south on 1200 West when he was hit by a westbound semi that police believe ran a red light at 800 North, said Orem Police Lt. Doug Edwards.

"Dave's the type of person who worked extremely hard for his family to support them," said Bob Cluff, owner of Minuteman Press and Lant's boss. "He loved his family dearly. He was very dedicated and one of the most dependable people I've ever associated with."

Lant had worked as a production manager at Minuteman Press for several years.

Aside from spending time with his family, Cluff said Lant was an avid rock climber.

Lant leaves behind a wife and three young girls.

A truck driver next to Lant saw their light change to green, but noticed that a west bound semitrailer coming down 800 North that didn't appear to be stopping.

Lant must not have seen the big rig, Edwards said, because he pulled out at the green light and was struck and killed.

The 25-year-old semi driver said he thought he had a green light, but several other witnesses said the light was red, Edwards said.

There are still several unanswered questions regarding the accident, Edwards said; however, it's possible that citations or charges may be filed against the Lindon truck driver, who Edwards said was also deeply affected by the accident.

"On a personal note, I knew David Lant," Edwards said. "He was a devoted husband and father and will be missed by all."

Cluff said he thought Lant would want people to remember that he was dedicated to his family.

"I think he was extremely conscientious of his work, the things he was involved in," Cluff said. "He wanted to be the best he could be."
