A 30-year-old Columbia man died Saturday after he lost control of a motorcycle and hit a parked semi-trailer in Elkridge, Howard County police said.

Juan Carlos Calderon Mejia was driving eastbound on Brookdale Drive near U.S. Route 1 when his 2001 Kawasaki motorcycle slid out of control and hit the rear of a parked tractor-trailer truck. Mejia was taken to the R. Adams Cowley Shock Trauma Center in Baltimore, where he died.

Police said speed was a contributing factor in the accident. Mejia was not licensed to drive a motorcycle, and he was not wearing a helmet, police said.
