The CHP's final coding listed the collision as a minor-injury crash, with units subsequently marked back in service.
One vehicle, described in the log as a Dodge Durango, had its occupants' information recorded by officers at the scene. A Chevrolet Bolt was also among the vehicles involved. The cause of the crash and whether any party was cited have not been released.
Lanes on northbound I-605 were blocked for a period while crews worked the scene, and a tow company was called to clear two of the vehicles. The CHP has not said whether speed, impairment, or any other factor contributed to the collision.

Frequently Asked Questions
Why does following distance matter so much in highway traffic?
Keeping space between vehicles gives drivers time to react when traffic ahead slows or stops suddenly, which can prevent one crash from triggering another.
Do crashes usually trigger additional collisions nearby?
Yes. Stopped or slowed traffic from an initial wreck can catch following drivers off guard, especially on busy freeways, leading to secondary crashes involving more vehicles.
What makes crashes with several vehicles difficult to investigate?
Investigators have to determine the sequence of impacts, how each vehicle was positioned and moving, and gather accounts from multiple drivers and witnesses, which takes more time than a two-car crash.
What typically causes pile-ups involving multiple vehicles?
Common factors include sudden braking, reduced visibility, heavy traffic volume, and drivers following too closely, though the specific cause of any crash is determined by investigators.
