12 News reported that a semi was involved in a crash along Interstate 10 near Eloy. According to the outlet, two people were treated at the scene for non-life-threatening injuries. No findings about cause or responsibility have been reported, and no one has been charged with or convicted of anything.
When a tractor-trailer is involved in a highway collision in Arizona, the injury claim is rarely limited to the person behind the wheel. Interstate motor carriers carry federally mandated liability coverage far larger than a typical private auto policy, and the company that employs the driver can be responsible for the driver's conduct on the job, for negligent hiring or supervision, and for the condition of the equipment. Arizona applies pure comparative fault under A.R.S. § 12-2505, so an injured person's recovery is reduced by their own percentage of responsibility but is never eliminated by it. Most injury claims must be filed within two years under A.R.S. § 12-542. The practical problem is evidence: electronic logging data, engine control module downloads, dashcam footage, and dispatch records sit in the carrier's hands and are routinely overwritten on short retention schedules, so a written preservation demand sent early often decides what can be proven later.
The Arizona Deadlines That Govern a Truck Crash Claim
Two deadlines matter most. The first is A.R.S. § 12-542, which gives an injured person two years from the date of injury to file a personal injury lawsuit. Miss it and the claim is gone regardless of how strong the evidence is.
The second applies only if a government entity may share responsibility, for example a public agency responsible for a roadway condition or a vehicle operated by a public employee. In that situation A.R.S. § 12-821.01 requires a written notice of claim served within 180 days of when the claim accrues, and that notice must state a specific sum the claimant will accept. The 180-day clock runs much faster than most people expect, and failing to serve the notice bars the claim against that entity even if the two-year window is still open.
If anyone dies as a result of a collision, Arizona handles the claim through two separate tracks: a wrongful death action brought by the statutory beneficiaries under A.R.S. § 12-611 through A.R.S. § 12-613, and a survival action under A.R.S. § 14-3110 for losses the person suffered before death.
Being "Treated at the Scene" Is Not a Medical Clearance
Roadside treatment confirms that a person was not in immediate danger. It does not rule out a concussion, a disc injury, internal bleeding, or soft tissue damage that announces itself two or three days later. Adrenaline suppresses pain, and commercial vehicle collisions transfer a great deal of force even at moderate speeds.
Get evaluated at an urgent care or emergency department the same day or the next, and describe every area that hurts, not just the worst one. Symptoms you never mention do not exist in the medical record, and insurers read gaps in treatment as proof that an injury was minor or unrelated. Follow the treatment plan you are given; unexplained stretches with no care are the most common reason otherwise solid claims get discounted.
Practical Steps in the First Two Weeks
Request the crash report as soon as it is available and read it for errors in the diagram, the direction of travel, and the listed insurance information. Photograph your vehicle before any repair and before a total-loss vehicle is released from storage, because the damage pattern is often the clearest evidence of how a collision happened. Write down what you remember while it is fresh, including road and traffic conditions.
Do not give a recorded statement to the trucking company's insurer or its adjuster before you understand your own injuries. Under A.R.S. § 12-2505, every percentage point of fault assigned to you reduces your recovery, and early statements are routinely used to build that percentage. Keep your own records: mileage to appointments, out-of-pocket costs, and days of work missed.
Finally, ask that a written evidence preservation letter go out to the motor carrier quickly. Logs, telematics, inspection and maintenance files, and driver qualification records are the heart of a commercial vehicle case, and they are far harder to obtain once routine retention periods expire.
