PHELAN, San Bernardino County, Calif., Nov. 8, 2026 — A GMC Denali rolled onto its side early Saturday morning, November 7, on northbound I-15 north of State Route 138, according to the California Highway Patrol. A car towing a trailer was reportedly involved in the collision as well.
The crash was initially logged as a collision with unknown injuries before the California Highway Patrol updated it to reflect that units were en route. The overturned GMC came to rest on its side, and it was not immediately confirmed whether anyone remained trapped inside. A box truck at the scene was helping direct traffic around the wreck in the slow lane while crews responded.
The driver of the GMC was reported to be out of the vehicle on the right shoulder. The CHP log noted the driver appeared to be showing signs of possible intoxication, with open containers reportedly seen in the vehicle, though this has not been confirmed through formal testing or charges. The extent of the injuries has not been confirmed so far.
Tow trucks were requested to clear the scene, and the CHP log shows at least one company dispatched to the location. The collision remains under investigation.
We are hoping for the best for those involved as more details come in.

Frequently Asked Questions
What typically causes a vehicle to roll over?
Rollovers usually happen when a vehicle's momentum shifts too fast during a sharp turn, an overcorrection, or a loss of control, especially in taller vehicles like SUVs and trucks with a higher center of gravity.
Are some roads more prone to rollover crashes than others?
Highway interchanges, curves, and ramps with higher speeds can see more rollovers, since drivers have less room to correct before a vehicle tips.
What injuries are common in rollover crashes?
Occupants can suffer head, neck, and spinal injuries, especially if unbelted, since they may be thrown against the roof or windows as the vehicle rolls over.
How can drivers lower the chance of a rollover in a sudden swerve or turn?
Keeping speed appropriate for the road, avoiding sharp overcorrections, and ensuring proper tire pressure and load distribution all help a vehicle stay upright during sudden maneuvers.
