Commercial truck crashes on Arizona’s interstates often involve catastrophic injuries and multiple potentially liable parties — the driver, the carrier, and others — layered with federal trucking regulations on top of Arizona law.
What Arizona law says
A.R.S. § 12-542 — Two-year statute of limitations for injury claims.
A.R.S. § 12-2505 — Pure comparative fault governs how shared responsibility affects recovery.
A.R.S. § 28-4009 — Financial-responsibility and registration rules that bear on commercial-vehicle liability and available coverage.
⏱ Key deadline
Injury lawsuits generally must be filed within 2 years (A.R.S. § 12-542); evidence should be preserved far sooner.
How truck accident cases work in Maricopa County
Truck cases combine Arizona injury law with Federal Motor Carrier Safety Administration (FMCSA) rules on hours of service, maintenance, and driver qualification. Evidence like the truck’s electronic logs must be preserved quickly, often through a litigation hold.
Frequently asked questions
Who can be liable in a truck accident?
Potentially the driver, the trucking company, a maintenance contractor, or a cargo loader — federal regulations can expand who is responsible.
Why are truck cases different from car cases?
They involve federal safety regulations, commercial insurance policies, and electronic evidence that must be preserved promptly.
What is a litigation hold?
A formal demand that the carrier preserve logs, maintenance records, and electronic data so they are not lost or overwritten.
