BLYTHE, Riverside County, Calif., Sept. 27, 2026 — Three construction workers died on Saturday morning, September 26, in a four-vehicle crash involving a big rig on eastbound Interstate 10 in Blythe. The California Highway Patrol said the collision happened in a construction zone east of Intake Boulevard.
The crash was reported around 5:15 a.m. A preliminary investigation found the big rig was traveling east at an unknown speed when it struck a parked attenuator truck and an unoccupied pickup before hitting a water truck, according to the agency. Three construction workers in the area were struck during that sequence and suffered fatal injuries.
The Riverside County Coroner's Office identified the men Saturday as 27-year-old Christopher Benavidez Guatemala of Coachella, 50-year-old Alfonso Vega Torres, also of Coachella, and 39-year-old Francisco Morales Mendoza of Tonopah, Arizona.
The truck driver, a 44-year-old Redlands man, suffered serious head and leg injuries and was taken to Desert Regional Medical Center in Palm Springs. Detectives do not believe alcohol or drugs played a role in the crash. The cause remains under investigation.
Our condolences go out to the families and friends of those who lost their lives.
When Work Zone Crashes on Highways Like Blythe's Turn Deadly
Early morning hours before sunrise carry particular risk in highway work zones. Visibility is limited, workers and equipment can be hard to spot against dark pavement, and drivers approaching at highway speed have less time to react to lane shifts or slowed traffic ahead.
Fatigue is also a factor at that hour. Long-haul truckers are usually driving overnight or in the early morning to meet delivery schedules, and reaction times suffer when a driver has been awake for many hours or is nearing the end of a shift. Combined with reduced lighting, a moment of inattention near a work zone can close the distance to workers or equipment before a driver can slow down.
According to the National Highway Traffic Safety Administration, 70 percent of people killed in large-truck crashes were occupants of other vehicles in 2023. Work zones add another layer of exposure because workers and slow-moving equipment share the road with vehicles still moving at highway speed.
Frequently Asked Questions
How long do investigations into fatal work zone crashes typically take?
Agencies like the CHP usually complete a preliminary review within days, but a full determination of cause, including speed analysis and equipment inspection, can take weeks or months.
How commonly is impairment a factor in fatal truck crashes?
It varies by case. Investigators routinely test for alcohol and drugs as part of every fatal crash review, even when early evidence points to other causes such as speed or visibility.
Where do fatal work zone crashes tend to happen most?
They cluster on highways and interstates with active construction, particularly in the hours before dawn or after dark when lighting is poor, and traffic patterns shift with little warning.
What to Do After a Big Rig Work Zone Crash in Blythe, CA
Anyone involved in or affected by a work zone crash should seek medical evaluation promptly, even if injuries aren't immediately obvious. Adrenaline can mask pain from impact for hours.
Get contact information for any witnesses at the scene if it's safe to do so, and request a copy of the official crash report once it's available from the responding agency. Photograph the scene, vehicle positions, and any visible signage or equipment if conditions allow.
For families of workers killed or injured in highway construction zones, the Riverside County Coroner's Office and CHP are typically the points of contact for official findings and updates as the investigation continues.
