A 41-year-old Lawrence man was transported by helicopter to Kansas University Hospital after a one-vehicle accident at Fifth and Colorado streets early Saturday morning.

At around 12:30 a.m., Mark Fraser was driving his truck west on Fifth Street when the vehicle veered into a ditch on the north side of the road, Lawrence Police Sgt. Susan Hadl said.

When the truck hit the embankment, Fraser was tossed from the vehicle through the passenger door, which opened on impact. Fraser suffered severe injuries from the accident, Hadl said.

As of late Saturday night, the hospital could not release information on Fraser’s condition.

Hadl said witnesses reported no other vehicles or animals that may have contributed to the accident, which occurred near 1708 W. Fifth St.
