A man driving north on the 5 freeway crashed into the sand barrels just before 8:00 am causing quite the traffic jam. Firefighters were dispatched to an overturned vehicle with possible entrapment. Before firefighters could arrive the Freeway Service Patrol checked on the male driver to notify CHP of any injuries. Paramedics checked on the man but he declined a transport due to non injury. He was wearing his seat belt at the time but tells CHP that he did not see the large yellow sand barrels. CHP is on scene investigating.
