IMHO, Cal Trans and the private contractor are both at fault for not having proper traffic control (signs & detours) at the work site. There should have been a detour in place for larger vehicles to exit and get around the concrete barriers. Cal Trans should of had a compliance officer at that site to insure everything (barriers, signs, flaggers, detours) were properly in place and being used correctly. I'm sorry you had to experience that, and the "Merry Go Round" that followed between Cal Trans and the private contractor pointing fingers and blaming each other is totaling unacceptable! Taking pictures was excellent! I'm retired from a trucking company and our boss had cameras in all the glove boxes of all the trucks to take pictures regardless of fault. Good Luck to you on the lawsuit! I would love to sit in the jury box of your lawsuit!
