(Newport Beach, CA) – Four people were hurt Wednesday when three vehicles collided on southbound MacArthur Boulevard in Newport Beach, according to authorities.
The collision happened at about 11:20 a.m. on southbound MacArthur Boulevard just south of Ford Road, authorities said. Fire crews declared a Level 1 Multi-Casualty Incident and took all four patients to hospitals in the area for care. According to fire department Public Information Officer David Gibson, "Fire crews declared a Level 1 Multi-Casualty Incident (MCI) and transported all four patients to area hospitals for treatment."
Police department Public Information Officer Heather Rangel reported that no one was killed, and noted the situation was still developing roughly an hour after the crash. Gibson said police were looking into what led to the collision early Wednesday afternoon, when the southbound lanes of MacArthur Boulevard stayed shut in the area as crews cleared the scene.
Drivers were asked to use other routes until the roadway reopened.

Analysis of the MacArthur Boulevard Collision
When several vehicles collide on a roadway like this, investigators generally work to reconstruct the sequence of events – the position and speed of each vehicle, the point of first impact, and whether any driver was making a turn or changing lanes. No fault has been established here, and police reported they were still investigating the cause. The discussion below is a general overview of the legal framework California applies to multi-vehicle crashes, not a conclusion about this incident.
Under California Civil Code section 1714(a), every person owes a duty of ordinary care and may be held responsible for harm caused by a failure to use that care. Where a crash involves more than one vehicle, more than one driver may share responsibility, and California Civil Code section 1431.2 provides that non-economic damages are allocated among the parties in proportion to each one's percentage of fault. That allocation typically becomes central in three-vehicle cases where responsibility may be divided.
Investigators often examine whether speed was appropriate for the conditions. The Basic Speed Law, California Vehicle Code section 22350, requires drivers to travel no faster than is reasonable and prudent given traffic, road, and visibility conditions. Separately, under Evidence Code section 669, if a driver is shown to have violated a safety statute and that violation proximately caused the injuries, a presumption of negligence can arise. Whether any of these principles apply here would depend entirely on evidence that has not yet been made public.
For those who are injured, California Civil Code section 3333 sets the measure of recoverable damages as the full detriment proximately caused, which can include medical expenses, lost income, and other losses.
What Injured People and Their Families Can Do
People hurt in a multi-vehicle crash can take a few practical steps to protect their interests. Obtaining a copy of the official collision report, keeping records of medical treatment, and preserving any photos or witness information can all matter later. A driver involved in an injury crash must file a written report with police within 24 hours under California Vehicle Code section 20008 and report to the DMV within 10 days under California Vehicle Code section 16000. It also helps to be aware that California Code of Civil Procedure section 335.1 generally sets a two-year deadline to bring a personal injury claim.
