Phoenix Truck Accident Lawyer

A Phoenix truck accident claim is built against the trucking company as well as the driver, because the company holds the logs, the maintenance file, and the insurance.

I-10 brings freight from the Southern California ports through downtown, and a belt of distribution centers along Loop 303 sends trucks into West Valley traffic every day.

Interstate carriers must carry at least $750,000 in liability coverage, and Arizona's constitution puts no cap on what a jury can award for an injury or a death.

Fault is often split among several companies, and Arizona lets each defendant point the jury at someone else.

The driver's hours-of-service records only have to be kept for six months, and the truck's engine data can be lost the day the tractor is repaired.

Truck crashes in the Valley follow the freight, and the freight runs on a few roads. Arizona's state freight plan ranks the twenty worst urban freight bottlenecks in the state, and the top ten are all stretches of I-10 in metro Phoenix, led by westbound I-10 between 27th and 51st avenues.^[1]

I-10 Through Downtown and the Broadway Curve

The plan describes I-10 as the corridor with direct connections to the Southern California ports, and as of 2019, California supplied 39 percent of the truck freight entering Arizona by weight. ADOT counts more than 300,000 vehicles on an average weekday through the Broadway Curve, rebuilt over 11 miles and finished in May 2025.^[2] Trailer sideswipes in the merge zones and lane changes across the widened lanes are among its typical truck cases, mapped on our page about crashes along the Broadway Curve.

I-17 and the Stack Interchange

The Stack is the downtown interchange where I-17 meets I-10, and the freight plan lists I-17 as a key commerce corridor connecting Phoenix to Flagstaff and I-40. ADOT's study of the I-10 Inner Loop between the Stack and the Split found up to 300,000 vehicles a day, trucks at 3.6 to 8.6 percent of the traffic, and a crash rate double that of other freeways in the region.^[3] North of the city, the descent between Sunset Point and Black Canyon City adds brake-heat and runaway-truck wrecks, covered on our page about I-17 crash claims north of the Stack.

Loop 303 and the West Valley Distribution Belt

The Maricopa Association of Governments reports that distribution centers and warehouses now line the southern end of Loop 303, where Amazon, REI, UPS, Chewy, and Puma have built or invested heavily in Goodyear, Litchfield Park, and Glendale.^[4] Farther north, interchanges at 43rd and 51st avenues give TSMC's Phoenix plant direct access. A crash with a truck from this corridor can involve the shipper that loaded the trailer, a logistics company that arranged the load, and a carrier hired for the run.

Loop 202 and the South Mountain Freeway

The 22-mile, $1.7 billion South Mountain Freeway opened on December 21, 2019, as an alternative to I-10 through downtown Phoenix.^[5] ADOT says it was not built as a truck bypass. Trucks use it like any Valley freeway, and long-haul through traffic is expected to stay on the posted I-8 and State Route 85 bypass.^[6] Its I-10 connections in west Phoenix and Chandler are where freeway-speed trucks meet merging commuters, covered on our page about the South Mountain Freeway's crash patterns.

Many of the serious truck wrecks we see in the Valley happen in traffic or at an intersection, where a loaded trailer still moving at highway speed meets a line of cars that had already stopped.

ADOT counts vehicles involved in crashes rather than truck-involved crashes, and its tables carry the tractor-trailer under the label truck tractor. These figures come from its most recent full report, the 2024 Crash Facts.^[7]

About 3.3 percent of the truck tractors in Arizona crashes were in a fatal crash, against roughly 0.5 percent of passenger cars, so a tractor-trailer in a crash was about six times as likely as a car to be in a deadly one. NHTSA counted 140 people killed in Arizona crashes involving large trucks that year, and 111 of them were outside the truck.^[8]

One of the country's largest fleets answers to an address in north Phoenix. Knight-Swift's 2025 annual report to the SEC describes the company as headquartered in Phoenix and operating one of North America's largest truckload fleets, an average of 21,428 truckload tractors that year.^[9] Its logistics segment also matches shippers with outside carriers, so a load with the company's name on the paperwork may have moved on someone else's truck.

That makes identification the first job. The USDOT number on the cab door shows whose federal operating authority the truck ran under, and that company, its insurer, and any broker that arranged the load go on the defendant list.

Location also decides where a carrier can be sued. Under Daimler AG v. Bauman, a corporation's principal place of business is a paradigm forum for general jurisdiction, where it can be sued on any claim.^[10] An Arizona family hurt by a Phoenix-based carrier on I-10 in California or New Mexico may be able to file at home in Maricopa County, though the crash state's law can still govern parts of the case.

Size changes the defense budget and nothing else. Big carriers keep big legal departments, and a claim against one often reaches a defense lawyer before it reaches an adjuster. At the end of the day though, a fleet with twenty thousand tractors owes the same qualified driver and the same brake inspection as a fleet with two.

Often, yes. On May 14, 2026, a unanimous U.S. Supreme Court held in Montgomery v. Caribe Transport II, LLC that a claim that one company "negligently hired another to transport goods" is not preempted by the FAAAA, the federal trucking deregulation statute, because "States retain authority to regulate safety."^[11] The Court assumed, without deciding, that the statute would otherwise reach the claim, and held that its safety exception saves it.

The claim asks what the broker checked before handing over the load: the carrier's operating authority, its insurance, and its federal safety record. The carrier in Montgomery held only a "conditional" FMCSA safety rating. A broker that should have rejected the carrier answers for that choice with its own insurance, and the theory is developed on our page about negligent carrier selection claims against brokers.

Arizona makes each defendant pay only its own percentage of fault, and the jury weighs the fault of everyone who contributed to the crash, whether or not that person or company was ever sued.^[12]

Under Arizona Rule of Civil Procedure 26(b)(5), a defendant that plans to blame a nonparty must name it in a notice served no later than 150 days after filing its answer, and a nonparty disclosed later gets no share of fault without good cause, reasonable diligence, and no unfair prejudice.^[13]

In a truck case, that notice is the carrier's list of who else it intends to blame: the broker, the shipper, the maintenance shop, a parts maker. If one of them was never sued and your two years to sue it have run, the fault a jury assigns to it is money no one pays you. We name the companies the evidence points to before the carrier does, and the mechanics are on our page about the empty-chair rule in Arizona courts.

Federal rules set which records a carrier must keep and for how long, and several periods run out before most injury claims are ready to file. Arizona applies the same driver, hours, and maintenance rules to every carrier operating in the state, intrastate haulers included.^[14] Our preservation letter names these records:

• Hours-of-service records and ELD data, kept six months, which show whether the driver broke the 11-hour driving limit or the 14-hour window.^[15]
• Driver vehicle inspection reports, the driver's end-of-day notes on brakes, tires, lights, and steering, kept three months.
• Maintenance and repair records, kept one year and six more months after the truck leaves the carrier's control.
• The driver qualification file, with the license history, medical certificate, and prior-employer checks, kept three years after the driver leaves.
• Post-crash drug and alcohol results, required after fatal crashes and certain injury and tow-away crashes, with alcohol testing cut off at eight hours and drugs at 32.
• Engine control module data, which no federal rule requires anyone to keep, and which a repair can overwrite.

The letter goes to the carrier, its insurer, and every other company in the chain, and asks that the tractor and trailer stay unrepaired until our experts inspect them. What it obliges a carrier to keep is explained on our page about what a preservation letter requires of a trucking company.

A Maricopa County truck claim is worth the full documented harm, reduced by any fault assigned to you and limited in practice by the insurance behind the truck. The Arizona Constitution forbids any law limiting damages for an injury or a death, so no statute sets the ceiling.^[16]

Shared fault comes off the top rather than ending the case. Under A.R.S. § 12-2505, a driver found 20 percent at fault keeps a claim for 80 percent of the damages.^[17] Carriers push that percentage as high as the evidence allows, so the engine data and the logs matter to value as much as to liability.

The damages include medical care through any lifetime care, lost wages and earning capacity, pain and suffering, and, for a family after a death, the losses Arizona's wrongful death statutes allow. Punitive damages require clear and convincing proof of the "evil mind" described in Linthicum v. Nationwide Life Insurance Co.^[18] Our page on Arizona's evil-mind test for punitive damages covers how it applies to a carrier.

Coverage sets the practical limit. A for-hire interstate carrier hauling general freight must carry at least $750,000 in liability coverage, $1 million for oil and certain hazardous materials, and $5 million for bulk hazardous substances.^[19] Arizona's adoption of the federal rules leaves those minimums out, so a local hauler's coverage is confirmed, never assumed. What moves a settlement inside those limits is on our page about the factors that move an Arizona truck settlement.

Two years. Under A.R.S. § 12-542, an injury lawsuit must be filed within two years after the claim accrues, usually the crash date, and a wrongful death claim within two years of the death.^[20]

A public vehicle shortens the calendar. If a city garbage truck, a county dump truck, or an ADOT maintenance vehicle was involved, a notice of claim with the facts and a specific dollar amount must reach the right public office within 180 days, and the lawsuit must follow within one year.^[21] Where each Valley notice goes is on our page about serving a notice of claim on a Maricopa County public body.

The evidence clock is shorter than either. The six-month hold on hours-of-service records runs out before a quarter of the two-year period has passed, which is why the preservation letter goes out first.
