That sucks 4 him , hope he is ok . Thier r alot of roads that have those same situations where we ride . You just have to keep scanning the road & expect the cages are gonna make the turn . The van had the right of way . I'v seen the same situation with driveways a cage slows & no blinker U try & pass they turn left in front of you. Ride safe, head up , eyes up keep scannin .
