BURBANK, Los Angeles County, Calif., Oct. 5, 2026 — A big rig overturned and collided with multiple vehicles early Sunday morning, October 4, on northbound Interstate 5 near Glenoaks Boulevard, according to the California Highway Patrol. The crash blocked lanes in both directions for hours and prompted a Sig-alert.
The California Highway Patrol said the collision was first reported around 3:32 a.m. as a two-vehicle crash blocking lanes, then was quickly updated to involve a semi-truck and multiple vehicles. Radio traffic described the tractor-trailer's trailer as flipped onto its side in the northbound lanes, with reports of five vehicles of unknown description also involved and blocking traffic. The agency's log listed the collision as having injuries of unknown severity, and the type was later reclassified as a tow-required crash with CHP units still en route.
The wreck proved complicated to clear. The truck's trailer ended up on the left shoulder, and part of the rig was reported hanging over the southbound side of the freeway, forcing CHP to close lanes on both the northbound and southbound sides at different points through the morning. A Sig-alert was issued for the northbound closure and later updated as crews worked the scene. Multiple tow companies, including heavy-duty rotator trucks, were called in to remove the overturned trailer and the other vehicles involved.
The investigation remains active. We hope those who were hurt recover fully.
Where Multi-Vehicle Freeway Pileups Tend to Cluster
Crashes involving several vehicles and a commercial truck tend to concentrate on high-volume interstate corridors where traffic merges, speeds vary, and lane changes happen in tight spaces. Stretches of freeway near major boulevard exits, like interchanges feeding local arterials, see frequent congestion that can turn a single slowdown into a chain-reaction collision when following vehicles don't adjust in time.
Early-morning hours on these corridors bring a mix of hazards: lower visibility, higher truck volumes as freight moves overnight, and drivers who may be fatigued after long shifts. When one vehicle, especially a loaded tractor-trailer, loses control or strikes stopped traffic, the result can involve several following vehicles before anyone has a chance to brake.
According to the National Highway Traffic Safety Administration, 33 percent of SUV-occupant fatalities occurred in vehicles that rolled over in 2023. On freeways with multiple travel lanes and limited shoulder space, a single rollover, whether from a passenger vehicle or a large truck, can block enough lanes to trap other vehicles behind it before traffic can safely stop.
Frequently Asked Questions
How can drivers stay safe around large trucks on the freeway?
Keep extra distance behind and beside trucks, avoid lingering in blind spots along their sides, and expect longer stopping distances when traffic slows suddenly near a truck.
Does fatigue play a role in truck crashes?
Fatigue is a recognized factor in commercial truck crashes, particularly during overnight and early-morning hours when drivers may be nearing the end of long hauls. Investigators typically examine hours-of-service logs as part of any crash review.
What should I do if I'm involved in a crash with a commercial truck?
Move to a safe area if possible, call 911, and wait for law enforcement to document the scene. Commercial truck crashes often involve separate reporting requirements beyond a standard crash report.
Why do trucks take so much longer to stop than cars?
Fully loaded trucks can weigh tens of thousands of pounds more than passenger vehicles, and that extra weight means a much longer stopping distance, especially at freeway speeds.
What to Do After a Multi-Vehicle Truck Crash in Burbank, CA
If you're involved in or witness a crash like this one, move to safety if you're able and call 911 right away. Even if you feel fine, get checked by a medical provider, since injuries from a multi-vehicle collision aren't always obvious right after impact.
Document what you can, photos of the scene, vehicle positions, and any visible damage, if it's safe to do so. Get the incident or case number from responding officers so you can follow up on the official report later. Burbank-area drivers caught in freeway backups from a crash like this should stay patient and avoid trying to merge around stopped traffic until CHP clears the scene.
