If you or someone you love was seriously hurt in a collision with an 18-wheeler, tractor-trailer, or commercial truck, finding an experienced semi truck accident lawyer in Arizona should be your very next step. These crashes are not like ordinary fender-benders. The forces involved are catastrophic, the legal landscape is far more complex, and the companies you are up against have teams of attorneys and insurers working to limit what they pay you from the moment the crash occurs. At Sher Law Group PLLC, we level that playing field for injured Arizonans — and we do it on a contingency basis, meaning no fee unless we win.

How Arizona Truck Accidents Differ from Regular Car Crashes

A fully loaded semi truck can weigh up to 80,000 pounds under federal law — compared to roughly 4,000 pounds for a typical passenger car. When something that size collides with a vehicle at highway speed, the results are often devastating: traumatic brain injuries, spinal cord damage, multiple fractures, internal organ trauma, and wrongful death. Understanding why these cases are legally distinct matters to your claim.

• Multiple liable parties: The truck driver, the trucking company, the cargo loader, the vehicle manufacturer, and even a maintenance contractor could all share fault in a single crash.
• Federal regulations: Commercial trucks operating in Arizona must comply with Federal Motor Carrier Safety Administration (FMCSA) rules — including hours-of-service limits, drug and alcohol testing requirements, and weight restrictions. Violations of these rules can establish negligence.
• Evidence that disappears fast: Electronic logging device (ELD) data, black-box event data recorders, and driver qualification files can be overwritten or destroyed. Trucking companies know this. An attorney who acts quickly can send a preservation letter — a legal hold notice — to prevent that evidence from vanishing.
• Higher insurance minimums: Under federal regulations, most interstate commercial trucks must carry at least $750,000 in liability coverage, and carriers hauling hazardous materials may be required to carry $5 million or more. Larger policies mean larger fights — and more aggressive defense teams.

Arizona Laws That Apply to Semi Truck Accident Claims

Arizona follows a pure comparative fault system under A.R.S. § 12-2505. This means that even if you are found partially at fault for the accident, you can still recover damages — your award is simply reduced by your percentage of fault. For example, if a jury determines you were 20% responsible and awards $500,000, you would receive $400,000. This makes it critically important to work with attorneys who know how to counter trucking companies' common tactic of shifting blame onto injured drivers.

Arizona's statute of limitations for personal injury claims is two years from the date of the accident under A.R.S. § 12-542. While two years may sound like plenty of time, truck accident cases require extensive investigation — accident reconstruction, subpoenaing maintenance records, deposing witnesses, and often working with industry experts. Starting that process early protects your rights. Our car accident attorneys at Sher Law Group understand how quickly critical evidence can become unavailable, and we move fast on your behalf.

Common Causes of Semi Truck Accidents in Arizona

Arizona's highways — including I-10, I-17, I-40, and US-60 — carry some of the heaviest commercial truck traffic in the southwestern United States. The most frequent causes of serious truck crashes we see include:

• Driver fatigue — a persistent problem despite FMCSA hours-of-service rules
• Distracted driving, including mobile device use
• Speeding, especially on long desert stretches where drivers underestimate their stopping distance
• Improperly secured or overloaded cargo shifting mid-transit
• Brake failure or other mechanical defects caused by poor maintenance
• Blind-spot accidents — large trucks have significant "no zones" on all four sides
• Wide-turn accidents in urban areas like Phoenix and Scottsdale
• Driving under the influence of stimulants or prescription drugs

Identifying the true cause — and the responsible party — often requires a thorough investigation that goes well beyond a police report. We also recommend reading our post on Arizona Comparative Negligence Law Explained to understand how shared fault could affect your specific case.

What Compensation Can You Pursue After a Truck Accident in Arizona?

Victims of serious truck accidents in Arizona may be entitled to recover both economic and non-economic damages. These can include:

• Past and future medical expenses — surgeries, hospitalizations, rehabilitation, and ongoing care
• Lost wages and diminished earning capacity if injuries affect your ability to work
• Pain and suffering, emotional distress, and loss of enjoyment of life
• Property damage to your vehicle
• Wrongful death damages if you lost a family member in the crash, including funeral expenses and loss of companionship

Arizona does not cap compensatory damages in most personal injury cases, which means the full scope of your losses can be presented to a jury. Punitive damages may also be available in cases where a trucking company's conduct was especially reckless — such as knowingly allowing a driver with a suspended CDL to operate a vehicle.
