Kris Jenner -- Injured in Car Crash ... Possible Broken Wrist (PHOTO GALLERY + VIDEO)

Kris Jenner was just involved in a car wreck off the 101 freeway near her home and we're told the impact was bad enough that she may have broken her wrist.

Law enforcement sources tell us Kris' white Rolls-Royce collided with a Prius -- the force of the impact deployed her airbag and absolutely destroyed the front end.

A Kardashian source tells us the Prius ran a red light. A law enforcement source tells TMZ it appears Kris was driving on a surface street when the Prius cut in front of her trying to get onto the 101 and caused the collision.

We're told Kris is being treated on scene by paramedics ... who we're told did not want to remove her from the car for fear of exacerbating her injury.
