A three-vehicle crash was reported on Summit Valley Road in Hesperia Sunday morning.
According to Pain In The Pass, the crash involved three vehicles.
One person was injured and transported by ambulance to a local hospital, the outlet reports. The California Highway Patrol's Victorville office is investigating, and a preliminary accident report is expected to provide additional information on how the vehicles ended up crossing into opposing lanes.
A Stretch of Road With a Troubled History
Summit Valley Road has also seen a fatal collision, according to VVNG.
More than a year earlier, on June 18, 2025, a four-vehicle collision near Foley Road killed a driver, VVNG also reported. And on November 18, 2025, a fatal multi-vehicle crash shut down Summit Valley Road between Highway 138 and Ranchero Road after a white SUV swerved and collided with a dark-colored Honda Accord and a black Nissan Armada SUV, according to the same outlet's coverage.
Summit Valley Road's Regional Role
Summit Valley Road connects Hesperia with the Cajon Pass.
The Telephone Canyon Road intersection has also drawn emergency crews for other reasons. A 5-acre brush fire broke out there on July 26, 2026, requiring aerial water drops and ground crews to put out, VVNG reported at the time, underscoring how frequently the area draws High Desert emergency responses.
Lane Drift Carries Legal Weight Under State Law
Under California Vehicle Code Section 21651(b), driving to the left of a dividing section or into opposing lanes of traffic is illegal, according to FindLaw's summary of the statute. Willful violations that result in injury or death can be prosecuted as felonies under CVC 21651(c), though investigators must first determine whether lane drift in a given crash was accidental or reckless.
The pattern on Summit Valley Road fits into a larger regional picture. San Bernardino County recorded 18,992 traffic crashes in 2024, resulting in 401 fatalities, according to RMD Law. More recent county data shows 14,743 total crash victims killed or injured in 2025, reflecting a 3% single-year decline even as the county's traffic fatality rate remains roughly double that of neighboring urban counties like Los Angeles and San Diego.
The cause of Sunday's crash on Summit Valley Road has not yet been determined.
