The driver of a semi trailer involved in the collision that killed a bicyclist on Valmont Road last August is set to stand trial in March on a charge of careless driving resulting in death.

Lucio Ramirez, 46, of Denver, was cited by the Colorado State Patrol after investigators said he failed to yield to Randy Herndon, 62, of Centennial, while Herndon was biking with a friend on Valmont Road.

During a hearing Monday, Boulder County Judge John Stavely scheduled Ramirez for a March 4 jury trial. He is also scheduled for a motions hearing on Feb. 6.

According to officials, at 6:50 a.m. Aug. 13, Ramirez was driving a truck owned by Villa Lobos Concrete east on Valmont Road when he made a left turn into the driveway of Pioneer Sand Landscape Supplies, 6379 Valmont Road.

Herndon was headed west on Valmont and collided with the rear tires of the truck. He was killed instantly.

The woman Herndon was riding with was not injured.

Prosecutor Christine Rinke indicated the Boulder County District Attorney’s Office extended an offer to Ramirez to plead guilty to the original count with a possibility of a sentence stipulation. Stavely indicated Ramirez would have until Feb. 25 to take that plea deal.

Ramirez’s attorney said sun was the cause of the accident.

Herndon was vice president of sales and software at the Reed Group in Broomfield.
