A 38-year-old Riverside man is dead after a traffic accident in Huntington Beach on Thursday, authorities announced.  

Officers with the Huntington Beach Police Department responded to reports of a traffic collision involving a motorcycle on Warner Avenue and Brightwater Drive at around 3:45 p.m. 

At the scene, police found the 38-year-old motorcyclist in the roadway. He was pronounced dead at the scene, an HBPD news release stated.  

Based on their preliminary investigation, authorities believe the motorcyclist was traveling at a high rate of speed on eastbound Warner Avenue when he appears to have lost control, resulting in a collision.
