Caitlyn Jenner Sues Prius Driver in Fatal PCH Crash

Caitlyn Jenner has just filed legal docs to hold the driver of the Prius in the fatal PCH crash at least partially responsible for the accident.

Caitlyn has filed a cross-complaint against Jessica Steindorff, the Prius driver, who was in front of Caitlyn at the time of the February crash. TMZ broke the story ... Caitlyn's SUV crashed into the Lexus, driven by Kim Howe, then continued on to strike the Prius. The Lexus careened into oncoming traffic and was struck by a Hummer, killing Howe.

Caitlyn is being sued by the driver and passengers of the Hummer, but in the new legal docs she says if she's on the hook she wants Steindorff to absorb at least partial responsibility.

Our sources say the basis for the alleged negligence on Steindorff's part is that she was sitting at the light after it turned green because she had been inattentive.

According to Jessica's attorney, Robert Simon, "It's unfortunate that she continues to not take responsibility for a crash she clearly caused."
