Following the accident, Montana Highway Patrol's Capt. Mark Wilfore told ET that the sister's accident was technically not a crash. Their car slid off the road into a ditch due to a storm. There were no injuries, and no damage to their car.

Kim posted an Instagram after the accident, writing, "Thank you God for watching over us and keeping us safe."
