Cajon Pass, CA (August 25, 2026) – At least one person was injured on Monday morning, August 24, in a three-vehicle collision on southbound I-15 at State Route 138 in the Cajon Pass. It happened around 7:21 a.m.
A white Honda Civic, a blue Tesla, and a third vehicle were involved, according to initial reports. One person reported back pain and numbness in the left leg.
Fire crews responded to treat the injured person, and the middle lane was blocked while crews worked. One of the vehicles was not drivable, and tow trucks were requested to remove it and another vehicle from the scene.
No further details about the cause of the wreck were released. We hope for a full recovery for the injured person.
Why Are Multi-Vehicle Crashes Frequent in the Cajon Pass?
The Cajon Pass is a steep mountain grade on I-15 connecting the Inland Empire to the High Desert, known for heavy truck traffic and frequent speed changes as vehicles climb or descend the grade. Multi-vehicle incidents are common in this stretch, since a sudden slowdown near the summit can catch following drivers off guard.
Back and leg symptoms, including numbness, are frequently reported after a rear-end or chain-reaction collision, since the sudden forward-and-back motion can affect the spine and nerves running through the lower back. These symptoms don’t always indicate a severe injury, but they’re taken seriously because nerve-related pain can sometimes point to something more significant.
Blocking a middle lane on a mountain grade like this can create significant backups, since traffic has fewer alternate routes available compared with a flatter stretch of highway. Tow truck crews working in this kind of terrain also have to account for the grade itself when safely removing a disabled vehicle.
