Quick answer
A Loop 303 truck accident often involves a tractor-trailer or delivery truck moving between West Valley distribution centers and the freeway system. Several companies may share responsibility, including the carrier, a shipper or a delivery contractor. Get medical care, document the truck's company name and USDOT number, and act before logs and video are lost. Arizona generally allows 2 years to file a lawsuit (A.R.S. 12-542).
A Loop 303 truck accident can be very different from a typical freeway crash. Loop 303 and the Loop 202 South Mountain Freeway carry heavy trucks, box trucks and delivery vans moving between West Valley warehouses and the rest of the Phoenix area. This page explains where these routes run, why crashes on them can involve several companies, what to do afterward and which Arizona deadlines may apply. It is part of our guide for Phoenix truck crash victims and is general information, not legal advice for your situation.
Why these freight routes matter in Phoenix
The West Valley has many warehouses, fulfillment centers and manufacturing sites. Many of them sit near Loop 303, I-10 and the Loop 202 South Mountain Freeway. That puts a large number of commercial vehicles on roads in fast-growing areas.
Loop 303: Goodyear to north Phoenix
Loop 303, also called the Bob Stump Memorial Parkway, is a freeway that ADOT describes (opens in a new tab) as running between I-10 in Goodyear and I-17 in north Phoenix. From I-10 it runs north through Glendale to US-60 (Grand Avenue) in Surprise. From there it heads east through Peoria, past Happy Valley Parkway, and ends at I-17.
ADOT is building an extension of Loop 303 south of I-10 in Goodyear, from Van Buren Street to MC 85. Work began in June 2026 (opens in a new tab) and is expected to take several years. Construction zones and new interchanges can change traffic patterns while work is underway.
Loop 202 South Mountain Freeway
The Loop 202 South Mountain Freeway (opens in a new tab) runs about 22 miles, connecting I-10 near 59th Avenue in the West Valley with I-10 and the Loop 202 Santan Freeway in the southeast Valley. It runs north and south near 59th Avenue, curves around South Mountain Park, and runs east and west along Pecos Road past Ahwatukee.
For trucks, it offers a path between the West Valley and the southeast Valley that avoids downtown Phoenix. That means freight moving between West Valley distribution centers and the southeast Valley may use this route instead of I-10 through the Stack.
How these routes connect
Loop 303 and the Loop 202 South Mountain Freeway both feed into I-10. A truck that leaves a Goodyear warehouse may travel Loop 303, then I-10, then Loop 202 in a single trip. Our guide to I-10 West Valley truck accidents covers the I-10 stretch through Tolleson, Avondale, Goodyear and Buckeye.
Common crash patterns near distribution centers
Every crash depends on its own facts. On these routes, crashes may involve:
Trucks entering or leaving the freeway slowly. A loaded tractor-trailer may take longer to reach freeway speed, which can lead to unsafe merges.
Wide right turns at ramp intersections. Long trailers often swing wide at signals near on-ramps and frontage roads, and a car may be caught in the gap.
Rear-end crashes in congestion. Heavy trucks need more distance to stop, especially when traffic slows suddenly at an interchange.
Blind-spot lane changes. A truck driver may not see a car alongside the trailer.
Shifting or poorly secured loads. Federal cargo securement rules appear in 49 CFR Part 393 (opens in a new tab), Subpart I.
Delivery vans under time pressure. Last-mile delivery drivers may be working tight schedules on unfamiliar roads.
Work zones. Construction on new segments and interchanges can narrow lanes and change exits.
Delivery trucks and vans on these routes
Not every crash on Loop 303 involves a semi. Box trucks, step vans and branded delivery vans also travel between West Valley hubs and neighborhoods. These cases can raise their own questions, such as whether the driver was an employee or a contractor, and which company's insurance applies.
Our guide to delivery truck and van accidents explains how those claims work.
Who may be responsible
A crash near a distribution center can involve a chain of companies. Depending on the facts, these parties may share fault:
the truck or van driver
the motor carrier or delivery contractor
the company that owns the tractor or trailer
the shipper or warehouse that loaded the cargo
a broker or logistics company, in some situations
a maintenance shop or parts maker
Arizona generally makes each defendant responsible only for its own share of fault, under A.R.S. 12-2506 (opens in a new tab), with exceptions such as when parties acted in concert or one was the other's agent or employee. Our guide on who is liable in a truck accident covers each one in more detail.
Evidence to protect
Important evidence may include the carrier's electronic logging device (ELD) data, dispatch and delivery records, route data, camera video and inspection files. Federal rules require carriers to keep driver records of duty status and supporting documents for at least 6 months, under 49 CFR 395.8(k) (opens in a new tab).
Warehouses and businesses near the crash may also have security cameras. That footage may be kept for only a short time.
What to do after a Loop 303 or Loop 202 truck crash
Call 911 and get medical care. Some injuries do not show symptoms right away.
Get the report number. Crashes on the freeway itself are generally investigated by Arizona Department of Public Safety troopers, and DPS explains how to request a copy of a report (opens in a new tab). Crashes at ramp intersections or on city streets may be handled by local police, such as Goodyear, Glendale, Surprise, Peoria or Phoenix.
Photograph the vehicle. Capture the company name, USDOT number, trailer number, any delivery branding and license plates.
Note the time and direction of travel. This helps match the crash to camera footage and delivery records.
Get witness names and phone numbers.
Keep records. Save medical bills, pay stubs and notes about missed work and daily activities.
Do not give a recorded statement to the other side's insurer without advice. You do not have to give one.
Talk to a lawyer early, before records are lost. You can request a free case review.
Insurance on commercial trucks
Under 49 CFR 387.9 (opens in a new tab), interstate for-hire carriers hauling general freight in vehicles with a gross vehicle weight rating of 10,001 pounds or more must carry at least $750,000 in liability coverage. Certain hazardous loads require $1,000,000 or $5,000,000. Carriers operating only within Arizona may be subject to different requirements. Delivery companies and contractors may carry separate policies. See our guide to truck insurance limits.
What a claim may include
No one can tell you in advance what a claim is worth. The value depends on your injuries, the evidence, the insurance available and how fault is shared. In Arizona, an injury claim may seek money for losses such as:
past and future medical bills
lost wages and reduced earning ability
pain, suffering and loss of enjoyment of life
vehicle repair or replacement and other property damage
Arizona's constitution bars laws that cap damages for injury or death, under Article 2, Section 31 (opens in a new tab). If a loved one died in the crash, a surviving spouse, child or parent, or the personal representative, may bring a wrongful death claim on behalf of the close family members listed in A.R.S. 12-612 (opens in a new tab).
Following your treatment plan and keeping bills, pay stubs and a simple journal of how the injuries affect your days can help document these losses.
Arizona law and deadlines
Time to file. Arizona generally allows 2 years from the date of injury to file a personal injury lawsuit, under A.R.S. 12-542 (opens in a new tab). Some exceptions can change that timing.
Public entities. If a city, county or the state may share fault, for example through a work zone or road design, a notice of claim is generally due within 180 days under A.R.S. 12-821.01 (opens in a new tab), and a lawsuit within 1 year under A.R.S. 12-821 (opens in a new tab).
Shared fault. Under A.R.S. 12-2505 (opens in a new tab), if you were partly at fault, your damages may generally be reduced by your share rather than barred.
Warehouse and delivery workers. If you were hurt while working, you may have a workers' comp claim and a separate claim against an outside company. Under A.R.S. 23-1023 (opens in a new tab), that third-party claim is deemed assigned to the comp insurer or self-insured employer if you do not file it within 1 year after the cause of action accrues.

Frequently asked questions
Where does Loop 303 run?
Loop 303 runs from I-10 in Goodyear north through Glendale and Surprise, then east through Peoria to I-17 in north Phoenix. ADOT began construction in 2026 on an extension south of I-10 in Goodyear toward MC 85.
Who may be responsible when a truck leaving a warehouse causes a crash?
Depending on the facts, the driver, the motor carrier, the company that owns the trailer, the shipper or warehouse that loaded it, or a delivery contractor may share fault.
Was the delivery van driver an employee or a contractor, and does it matter?
It can matter. Whether a driver is an employee or an independent contractor can affect which company and which insurance policy may be responsible. The contracts and records usually need to be reviewed.
What if the crash happened at a ramp intersection or frontage road, not on the freeway itself?
The same basic rules apply. The Arizona Department of Public Safety generally handles crashes on interstates and state highways, while crashes on city or county roads, including some ramp intersections and frontage roads, usually go to the local police or sheriff. So it helps to note exactly where the crash happened.
Can road design or construction be part of the cause?
Sometimes. If a public entity's road design, signals or work zone may have contributed, a notice of claim is generally due within 180 days under A.R.S. 12-821.01, and a lawsuit within 1 year under A.R.S. 12-821. Public entities may also have special defenses to some road design claims (A.R.S. 12-820.03), so these claims depend heavily on the facts.
How much insurance does a semi-truck on Loop 303 have to carry?
Interstate for-hire carriers hauling general freight in vehicles of 10,001 pounds or more must carry at least $750,000 under 49 CFR 387.9, with higher minimums for certain hazardous loads. Local or intrastate carriers may be subject to different rules.
