Authorities tell TMZ that the Los Angeles County Sheriff’s Department has determined Jenner had nothing in his system when his Escalade rear-ended another vehicle on the highway.
In fact, his blood-alcohol level was 0.0.
"He was balanced out. He wasn't under the influence. We know that," one law enforcement official says.
Jenner was involved in a multi-car pile-up a few days ago, as the Lexus in front of him slammed on its brakes to avoid hitting the car that had stopped suddenly in front of it.
Jenner, however, was unable to stop his black Escalade in time.
He slammed into the Lexus, which was being driven by 69-year old Kim Howe, sending it into the oncoming lane of traffic, where a Hummer crashed into it head-on.
Howe, a neighbor of the Kardashians in Calabasas, was pronounced dead at the scene.
“My heartfelt and deepest sympathies go out to the family and loved ones, and to all of those who were involved or injured in this terrible accident," Jenner said via statement the next day, adding:
"It is a devastating tragedy and I cannot pretend to imagine what this family is going through at this time. I am praying for them. I will continue to cooperate in every way possible."
