Who's at fault? Dash cam catches sudden lane change before 405 pileup in Irvine

A sudden lane change set off a multi-car collision on the 405 Freeway in Irvine, according to a Nov. 20, 2025, Juice Unlocked post. The post's banner called it a "chain reaction pileup" and asked followers: Who's at fault?

The post was a plug for The Injury Firm, an Orange County accident law firm, with the call line 949-828-2125.

What the footage shows

The roughly 19-second dash-cam clip rolls under a freeway overpass on a sunny day. A white sedan cuts across lanes in front of the camera car, then a red pickup swerves in from the left as overhead signs for the 405 North and the 55 Freeway, Exit 9A, come into view. The camera jolts and tilts as the car veers toward the right-side wall.

The post does not say when the crash happened, how many vehicles were involved, whether anyone was hurt or who was found at fault. Someone in the car can be heard reacting.

The pitch

The rest of the carousel is the firm's message. A short video of its team outside an office building carries the line "Insurance companies have lawyers! You should too!!!" A final slide lists dollar amounts the firm advertises by case type, including three at $250,000 for auto accidents, and says people can get paid for pain, missed work and future treatment.

As of November 2026, The Injury Firm's website lists car accidents and multi-vehicle pileups among its practice areas, offices in Anaheim Hills and Irvine, a free case evaluation and (949) 575-8875 as its main number. It says clients pay only if it wins and that past results do not guarantee future outcomes.
