Truck Accident Lawyer in Arizona

Arizona's statute of limitations for truck accident personal injury claims is two years from the date of the crash under A.R.S. § 12-542. Pure comparative fault under A.R.S. § 12-2505 means no percentage of fault bars the injured party's recovery. But the two-year clock is misleading in truck cases because the critical evidence — the carrier's electronic logging device data, driver qualification files, post-trip inspection reports, and dispatch records — is subject to federal retention periods that are shorter than two years. Under 49 CFR Part 395, ELD records must be retained for only six months. Under 49 CFR Part 391, driver qualification files must be maintained while the driver is employed but can be purged after departure. A spoliation letter sent within the first weeks after the crash — before the carrier's routine document destruction cycle runs — is what preserves this evidence. Waiting even six months can mean the ELD data showing the driver exceeded hours-of-service limits no longer exists.

Arizona's commercial vehicle weight and length regime under A.R.S. § 28-1100 sets a 20,000-pound single-axle limit, a 34,000-pound tandem-axle limit, and an 80,000-pound gross vehicle weight ceiling for combinations of five or more axles. The statute carves out two narrow exceptions: vehicles with idle-reduction technology may exceed the baseline by up to 550 pounds under A.R.S. § 28-1100(H), and vehicles fueled primarily by natural gas, battery electric, or hydrogen may exceed the baseline up to 82,000 pounds under A.R.S. § 28-1100(I). Overweight trucks have longer stopping distances, higher rollover risk, and cause more severe damage on impact. A carrier operating above the statutory limits on I-10 through the Phoenix metro or on I-40 through Flagstaff is in per se violation of Arizona law — a fact that shifts the negligence analysis significantly in the injured party's favor under A.R.S. § 12-2505.

Federal motor carrier safety regulations apply to all interstate carriers operating through Arizona and to intrastate carriers under 17 A.A.C. 5, which incorporates 49 CFR Parts 350 through 399 for Arizona-licensed carriers. ADOT's Enforcement and Compliance Services Division and the Arizona Department of Public Safety's Commercial Vehicle Enforcement Bureau conduct inspections at fixed weigh stations and through roving enforcement on the I-10, I-17, and I-40 corridors. The Nogales port of entry on the US-Mexico border generates additional heavy truck traffic that must clear both federal customs inspection and state weight/safety compliance. A serious truck accident case requires pulling the carrier's FMCSA safety profile (SMS scores, inspection history, crash history), the driver's CDL record and medical certificate, and the post-crash drug and alcohol test results mandated by 49 CFR Part 382. The carrier's insurance — a minimum of $750,000 under 49 CFR § 387.9 for general freight, higher for hazmat — provides a substantially larger policy than the at-fault driver's personal auto insurance.

The most dangerous aspect of Arizona truck cases is the government-entity crossover. ADOT operates maintenance vehicles, construction zone equipment, and highway patrol support vehicles on every major corridor. If an ADOT vehicle or a government-contracted truck contributed to the crash — a poorly marked construction zone, a maintenance truck without adequate warning signals, a government vehicle merging unsafely — the 180-day Notice of Claim requirement under A.R.S. § 12-821.01 applies. The lawsuit must then be filed within one year under A.R.S. § 12-821, not the standard two years. Arizona courts strictly enforce both deadlines. An attorney evaluating a truck crash on an Arizona highway must immediately determine whether any government entity or government-contracted vehicle was involved, because missing the 180-day notice window permanently extinguishes the claim against that entity.
