A devastating wrong-way head-on crash on Interstate 5 in Yolo County claimed two lives and left a third person with major injuries late Monday night. The collision, which occurred during the overnight hours of March 10, 2026, has prompted an ongoing investigation by the California Highway Patrol into whether alcohol or drugs played a role.
The crash unfolded just south of County Road 8 near the small town of Dunnigan, where a vehicle traveling the wrong direction on the freeway collided head-on with an oncoming car, leaving behind a scene of immense loss for the families of those involved. As investigators work to piece together the full circumstances of the tragedy, the surviving victim remains hospitalized with serious injuries, and two families are left grieving the sudden and senseless deaths of their loved ones.
What Happened on the Wrong-Way Head-On Crash
According to the CHP’s Woodland office, the crash occurred at approximately 11:52 PM on Monday, March 10, 2026, on Interstate 5 just south of County Road 8, a few miles south of the town of Dunnigan in Yolo County. The collision was reported by the Sacramento Bee.
Investigators determined that one vehicle — a Honda — was traveling northbound in the southbound lanes of I-5 at the time of the crash. The wrong-way Honda struck a southbound Toyota head-on. The Toyota was occupied by both a driver and a passenger, while the Honda’s driver was traveling alone.
The consequences were fatal for two of the three people involved. The driver of the Honda and the passenger in the Toyota both died as a result of injuries sustained in the collision. The driver of the Toyota survived but suffered major injuries and was transported by ambulance to a nearby hospital for treatment. The names and ages of all three individuals have not yet been publicly released. The Yolo County Coroner’s Office will identify the deceased once their families have been notified.
CHP investigators have indicated that alcohol or drugs are believed to have been a contributing factor in the crash. The investigation remains active, and the CHP’s Woodland office is asking anyone with information about the collision to contact investigators directly.
The Dangers of Wrong-Way Driving in California
Wrong-way crashes are among the most deadly types of traffic accidents precisely because they involve direct, head-on collisions — often at highway speeds — that leave drivers with almost no time to react. When a vehicle enters a freeway traveling against the flow of traffic, the consequences can be catastrophic within seconds.
The National Transportation Safety Board has identified impairment from alcohol or drugs as the single most common factor in wrong-way driving incidents, with a significant portion of these crashes occurring during nighttime or overnight hours. California’s interstate highways, including I-5, see consistent traffic at all hours, making wrong-way entries especially dangerous.
For innocent drivers and their passengers — like the occupants of the southbound Toyota in this crash — there is often nothing that could have been done differently. These accidents are a painful reminder that even the most cautious, law-abiding driver can be placed in harm’s way by the reckless decisions of others.
California Wrongful Death Claims After a Fatal Crash
When a family loses a loved one due to another person’s negligence — including impaired driving — California law provides a legal avenue for justice through a wrongful death claim. Under California Code of Civil Procedure § 377.60, the surviving spouse, domestic partner, children, and other financially dependent family members of a deceased victim may bring a wrongful death lawsuit against the responsible party.
A successful wrongful death claim can provide compensation for a range of losses, including funeral and burial expenses, loss of the deceased’s financial support and household contributions, loss of companionship, love, and guidance, and the emotional suffering experienced by surviving family members.
Wrongful death cases involving DUI or drug-impaired driving can also support claims for punitive damages in certain circumstances, as California law allows courts to punish particularly reckless or egregious conduct beyond compensatory awards alone.
Families who have lost someone in a crash caused by a wrong-way or impaired driver should consult with an experienced California personal injury attorney as soon as possible to understand their rights and options.
California’s DUI Laws and Civil Liability
Under California Vehicle Code § 23152, it is illegal to operate a motor vehicle while under the influence of alcohol, drugs, or a combination of both. A driver who causes injury or death while impaired can face both criminal prosecution and significant civil liability.
In civil cases, the legal standard does not require a criminal conviction. Even if criminal charges are reduced or dismissed, families of victims may still pursue a civil wrongful death or personal injury claim based on the preponderance of evidence standard — a lower bar than what applies in criminal court.
If investigators confirm that impairment was indeed a factor in this I-5 crash, the surviving driver of the Toyota and the family of the deceased Toyota passenger may have strong grounds to pursue compensation from the at-fault driver’s estate or insurance carrier.
Understanding Comparative Fault in California
California follows a pure comparative fault rule under Civil Code § 1714. This means that a victim’s ability to recover compensation is not eliminated simply because they may have contributed in some way to an accident, though in a straightforward wrong-way collision, the fault almost certainly rests entirely with the wrong-way driver.
For injured survivors and families of those killed in crashes caused by another driver’s negligence or impairment, comparative fault is generally not a significant barrier to recovery. An experienced attorney can evaluate the specific facts of a case and advise on how liability is likely to be assigned.
How a Personal Injury Settlement Calculator Can Help You Understand Your Case
If you or a family member has been injured — or you have lost a loved one — in a crash caused by a negligent or impaired driver, one of the first questions you may have is: What is my case worth? While every case is different and no online tool can replace the advice of a qualified attorney, a personal injury settlement calculator can help you begin to understand the types of compensation that may be available to you.
Generally speaking, a California personal injury or wrongful death claim may account for economic damages such as medical expenses, lost wages, and future earning capacity, as well as non-economic damages including pain and suffering, emotional distress, and loss of consortium. In cases involving drunk or impaired driving, courts may also consider punitive damages. The GJEL Accident Attorneys website offers resources to help injured victims and grieving families get a clearer picture of what their claim may involve.
It is important to understand that a fatal accident settlement calculator provides an estimate based on the information you input — it is not a substitute for a thorough legal evaluation by an experienced attorney. Factors such as the severity of injuries, the degree of negligence, available insurance coverage, and the long-term impact on a victim’s quality of life can significantly influence the final value of a claim.
In cases like this one — where impairment is suspected, and two people lost their lives — the damages at stake can be substantial, and having skilled legal representation can make a critical difference in the outcome.
