WHILE DRIVING SLOWLY (~10 MPH) SB I PREPARED TO MAKE A RIGHT-TURN (WB), IN THE ONLY LANE THAT TURNS RIGHT. AS I NEARED THE INTERSECTION THE LIGHT TURNED GREEN, ENABLING ME AND THE (1) LANE ON MY LEFT TO GO (IT GOES SB). NO CAR WAS AHEAD OF ME (TO TURN).

THE 1ST CAR IMPACTED WENT BACKWARD (AND TO THE RIGHT) HITTING THE CA
