A University of Colorado student is hospitalized with life-threatening injuries after being hit by a pickup truck on Regent Drive near Kittredge Loop on the CU campus about 6 p.m. Tuesday.

The pedestrian suffered a serious head injury in the crash and was taken to Boulder Community Hospital.

Police said both the driver and victim are male CU students, but their names weren’t released.

Boulder police Sgt. Jack Walker said the pedestrian was crossing Regent — and was not in a crosswalk — when he was hit by a blue Toyota pickup truck.

Police spokeswoman Kim Kobel said no speeding, drugs or alcohol appear to have been involved, and the driver is cooperating with police. The driver told police he was going slowly because the sun was impairing his view.

According to police radio scanner traffic, officers initially reported that the accident was fatal.
