In Arizona, a truck accident claim must generally be filed within 2 years of the crash, and the state follows pure comparative negligence. Federal FMCSA regulations govern the carrier's conduct, while Arizona law governs the injury claim itself — which is why the state your crash happened in changes what your case is worth and how long you have.
How fault works in Arizona
Arizona is a pure comparative state — recovery is reduced by your share of fault but is not barred at any threshold.
This matters more than most people expect. The trucking company's insurer is not only arguing about how much you were hurt — it is arguing about what share of the crash was your responsibility, because every percentage point shifted onto you reduces what it pays. In Arizona, that pressure is constant throughout the claim. See who can be held liable.
Where truck crashes happen in Arizona
I-10 across Arizona is one of the busiest long-haul freight routes in the western United States, and I-19 carries produce and manufacturing freight north from the Nogales port of entry. Extreme summer heat contributes to tire failures on these corridors, and dust storms on I-10 between Phoenix and Tucson have produced repeated multi-vehicle truck pileups.
The corridors that carry the most commercial truck traffic:
- I-10 (Phoenix–Tucson and the California–Texas through route)
- I-17 (Phoenix–Flagstaff)
- I-40 across northern Arizona
- I-8 in the southwest
- I-19 (Tucson–Nogales)
Crashes on these routes tend to involve interstate carriers, which means the federal safety regulations — hours-of-service limits, maintenance duties, drug and alcohol testing — apply alongside Arizona negligence law.
Arizona-specific issues worth knowing
Before you talk to an adjuster
- The Arizona Constitution prohibits statutory caps on damages for death or personal injury, making Arizona one of the few states where compensatory damages cannot be legislatively limited.
- Claims against Arizona public entities require a notice of claim within 180 days and suit within one year.
- Heat-related tire failure is a recurring issue on Arizona interstates and points toward maintenance and inspection records under 49 CFR Part 396.
Federal rules do not change at the state line
Whatever state you were injured in, a carrier operating in interstate commerce answers to the same federal standard: at least $750,000 in liability coverage, hours-of-service limits under 49 CFR Part 395, and a six-month retention floor on driver duty records. What changes from state to state is the deadline, the fault rule, and any damages limits.
That combination is why the same crash can be worth substantially different amounts in two neighboring states — and why preserving the truck's data matters equally everywhere.
