Glendale, AZ (November 11, 2026) – One person was killed and two others were injured Tuesday morning, November 10, after a vehicle crashed into a freeway underpass along Loop 101 Agua Fria near Union Hills Drive in Glendale. According to the Arizona Department of Public Safety (DPS), the single-vehicle accident occurred around 5 a.m. and prompted an emergency response from state troopers and local firefighters.
DPS troopers responded near the northbound lanes of Loop 101 after receiving reports that a vehicle had struck the underpass. Emergency crews arrived to find a heavily damaged vehicle positioned against a corner of the structure.
Authorities confirmed that one person died at the scene. Two other people were transported to a nearby hospital for treatment, including one person with serious injuries and another with minor injuries.
Officials have not released the identities or ages of those involved. Authorities also have not specified whether the deceased person was driving or riding as a passenger.
Traffic camera footage from the Arizona Department of Transportation showed firefighters working around the damaged vehicle. Emergency personnel appeared to be cutting through portions of the wreckage to gain access to the occupants.
Firefighters from Phoenix and Glendale assisted DPS at the scene. The emergency response involved securing the damaged vehicle, reaching those inside, and providing medical assistance to the surviving occupants.
Investigators confirmed that no other vehicles were involved in the collision. Authorities have not explained why the vehicle left its travel path or struck the underpass.
DPS officials said impairment had not been ruled out as a possible contributing factor. However, authorities have not confirmed that alcohol or drugs were involved, and no official cause has been announced.
The collision forced the closure of the affected northbound freeway lanes for several hours while emergency crews responded and investigators examined the scene. Southbound traffic was not affected by the closure.
The northbound freeway reopened shortly before 7 a.m., according to the initial report. Authorities have not announced any charges or released additional findings about the circumstances surrounding the crash.
The Arizona Department of Public Safety continues to investigate the fatal collision.
What Causes Vehicles to Crash Into Freeway Underpasses?
Single-vehicle accidents involving freeway structures can occur when motorists lose control or leave their intended travel path. Potential contributing factors include driver distraction, excessive speed, fatigue, impairment, mechanical problems, and roadway conditions.
Freeway underpasses and bridge supports are fixed structures that do not move or absorb impact forces in the same manner as another vehicle. When a car strikes one of these structures, the sudden deceleration can cause substantial damage and serious injuries.
The severity of a collision depends on vehicle speed, the angle of impact, the location of the strike, and the vehicle’s safety features. Occupants may experience different injuries depending on their seating positions and the extent of passenger compartment damage.
Investigators must examine physical evidence before determining why a vehicle struck a fixed object. The fact that a vehicle hit an underpass does not automatically establish that the driver was speeding or impaired.
In the November 10 Glendale accident, DPS confirmed that a vehicle struck an underpass near Loop 101 and Union Hills Drive. Authorities have not established what caused the collision.
What Does Arizona Law Say About Safe Driving on Freeways?
Arizona law requires drivers to operate their vehicles at speeds appropriate for existing roadway and traffic conditions. Under Arizona Revised Statutes § 28-701, motorists must not drive faster than is reasonable and prudent under the circumstances.
Drivers must also maintain proper control of their vehicles and follow applicable lane-use requirements. These responsibilities apply on freeways, where higher travel speeds can increase the consequences of a collision.
A driver who loses control may have violated a traffic law if negligent conduct contributed to the accident. However, an unexpected mechanical failure or another circumstance may affect the legal analysis.
In the Glendale collision, DPS has not announced that speeding, improper lane use, or another traffic violation caused the crash. Investigators continue to examine the circumstances.
Can Impaired Driving Cause a Single-Vehicle Accident?
Alcohol and certain drugs can affect a driver’s judgment, coordination, reaction time, and ability to maintain proper vehicle control. These effects may increase the risk of leaving the roadway or striking a fixed object.
Arizona law prohibits driving while impaired under Arizona Revised Statutes § 28-1381. The law establishes offenses involving impairment and certain alcohol or drug-related conditions.
Investigators may examine toxicology findings, witness statements, and other evidence when impairment is suspected. However, impairment cannot be established solely because a vehicle crashed without another vehicle being involved.
In the November 10 Glendale accident, DPS stated that impairment had not been ruled out. Authorities have not confirmed that alcohol or drugs contributed to the collision.
Why Are Fixed-Object Collisions Often Serious?
Collisions with fixed objects can cause severe injuries because the vehicle may stop abruptly after striking a structure that does not move significantly. The force of the impact can damage the vehicle’s front end, passenger compartment, and safety systems.
Potential injuries include traumatic brain injuries, fractures, spinal injuries, chest trauma, and internal bleeding. The severity depends on the circumstances and whether the vehicle’s protective structures remain intact.
Emergency responders may need specialized equipment to reach occupants when vehicle doors or other components become damaged. Extrication procedures can involve cutting or removing parts of the vehicle to create access.
In the Glendale accident, traffic cameras showed firefighters working to reach occupants inside a heavily damaged vehicle. One person died, while two others were hospitalized with injuries of differing severity.
Can Passengers File Injury Claims After a Single-Vehicle Crash?
Passengers injured in a single-vehicle accident may have grounds to pursue compensation when another party’s negligence caused their injuries. Potential claims may involve the driver, another responsible party, or applicable insurance coverage.
Passengers generally are not responsible for operating the vehicle, although the specific circumstances can affect available claims. Investigators may examine whether negligent driving, a vehicle defect, or another factor contributed to the collision.
Arizona follows a comparative negligence system under Arizona Revised Statutes § 12-2505. A claimant’s recovery may be reduced according to their share of fault, subject to applicable statutory rules.
In the November 10 Glendale accident, authorities have not identified which occupant was driving or riding as a passenger. Any potential personal injury claim would depend on the investigation and available evidence.
What Rights Do Families Have After a Fatal Single-Vehicle Accident?
Arizona law allows certain surviving family members to pursue wrongful death claims when another party’s legally actionable conduct causes a person’s death. Under Arizona Revised Statutes § 12-612, eligible claimants may include a surviving spouse, children, parents, or the deceased person’s estate in certain circumstances.
Potential compensation may include qualifying financial losses and other damages recognized under Arizona law. The available recovery depends on the circumstances and the evidence supporting the claim.
A wrongful death claim requires proof that another party’s wrongful conduct caused the death. The fact that an accident was fatal does not automatically establish negligence or create a valid claim.
In the Glendale collision, one person died after a vehicle struck a freeway underpass. Authorities have not identified the deceased person or determined who was driving. Any potential wrongful death claim would depend on additional findings.
Can Roadway Conditions Contribute to an Underpass Collision?
Roadway conditions may contribute to certain accidents when drivers encounter hazards that affect visibility, traction, or vehicle control. Potential concerns can include damaged pavement, debris, inadequate drainage, or other dangerous conditions.
However, the presence of a bridge support or underpass does not automatically establish that the roadway was defective. Determining whether a dangerous condition contributed to an accident may require engineering evidence and information about the roadway’s design and maintenance.
Claims involving public roads may be subject to special legal requirements. Arizona law provides certain immunities and defenses to public entities, and applicable notice deadlines may differ from those governing ordinary negligence claims.
In the November 10 Glendale collision, authorities have not identified a roadway defect or maintenance problem as a contributing factor. DPS continues to investigate why the vehicle struck the underpass.
What Evidence Is Important After a Fatal Single-Vehicle Crash?
Evidence can help investigators determine why a vehicle left its travel path and struck a fixed structure. Photographs of the vehicle, roadway markings, impact location, and surrounding conditions may provide important information.
Investigators may examine tire marks, vehicle electronic data, and mechanical components to reconstruct the collision. Available traffic camera footage may also help establish the vehicle’s movements before impact.
Medical records and official investigative findings can help clarify the injuries sustained and the circumstances surrounding the crash. Toxicology findings may become relevant when impairment is being investigated.
In the Glendale accident, traffic cameras captured emergency personnel working around the damaged vehicle. Authorities have not released reconstruction findings or confirmed what caused the collision.
How Long Do Injured People Have to File a Lawsuit in Arizona?
Arizona generally provides two years to file personal injury and wrongful death lawsuits under Arizona Revised Statutes § 12-542, subject to applicable exceptions. The deadline ordinarily begins on the date of injury or death.
Claims against public entities may have additional requirements. Arizona Revised Statutes § 12-821.01 generally requires a notice of claim to be filed within 180 days after a claim accrues, subject to statutory provisions and exceptions.
Insurance policies may also establish reporting requirements that differ from court filing deadlines. Injured individuals and surviving families may need to preserve medical records, accident reports, and other evidence while evaluating their options.
In the November 10 Glendale collision, investigators have not established whether another party’s negligence caused the accident. Any potential legal claim would depend on the evidence and applicable Arizona law.
