SEMI CROSSES INTO ONCOMING TRAFFIC: 71-YEAR-OLD ADELANTO WOMAN KILLED
📍 PALMDALE ROAD / SR-18 | ADELANTO, CALIFORNIA
A 71-year-old woman is dead after investigators say a tractor-trailer lost control, crossed into opposing traffic and collided with her pickup Tuesday morning in Adelanto.
And the biggest question tonight is brutally simple:
WHY DID THE SEMI LOSE CONTROL?
According to the preliminary investigation from the San Bernardino County Sheriff’s Department, the crash happened around 7:37 a.m. Tuesday, Aug. 18, on Palmdale Road east of Richardson Street.
Investigators say a 60-year-old man was driving a tractor-trailer eastbound when he lost control.
The semi then crossed into the westbound lane.
Coming the opposite direction was a 71-year-old Adelanto woman driving a dark-blue 2022 Chevrolet Silverado.
The vehicles collided.
🚨 The woman was pronounced dead at the scene.
🚑 The truck driver survived and was transported to a hospital in stable condition.
The victim’s identity has not yet been publicly released.
But here’s where this story gets deeper.
🔎 INVESTIGATORS KNOW THE TRUCK LOST CONTROL. THEY DON’T YET KNOW WHY.
There has been no verified finding that speed, distraction, fatigue, impairment, tire failure, brake failure, steering failure, cargo movement or a medical emergency caused the crash.
That distinction matters.
A tractor-trailer crossing into opposing traffic tells us what happened.
It doesn’t yet tell us why it happened.
The Major Accident Investigation Team is investigating, and authorities are asking witnesses to come forward.
Photos from the actual scene show the staggering aftermath: both vehicles left the roadway, the Silverado suffered catastrophic damage, and debris was scattered around the crash site.
