Multiple lanes of I-5 (at milepost 146) near Kent were blocked after the collision, which occurred at approximately 12:14 a.m. early Sunday, and blocked traffic for over three hours.

  • Vehicle 1 struck the left side of Vehicle 2.
  • Vehicle 1 rolled multiple times before coming to rest in lane 1.
