What Is a Jackknife Truck Accident?

A jackknife accident occurs when a tractor-trailer folds at the hitch point, causing the trailer to swing perpendicular to the cab — forming an angle resembling a folding jackknife blade. These accidents typically unfold in seconds and are nearly impossible to correct once initiated, often sweeping across multiple lanes.

Common Causes

→Sudden or hard braking on wet, icy, or slick pavement
→Excessive speed on curves or downgrades
→Improper load distribution or overloaded trailer
→Brake system failure or malfunction (FMCSA maintenance violation)
→Driver overcorrection or abrupt steering input
→Rear axle lockup before front axle during emergency braking

Common Injuries

→Traumatic brain injury (TBI)
→Spinal cord injury and paralysis
→Crush injuries from multi-vehicle involvement
→Burns from fuel leaks and fire
→Broken bones and internal organ damage
→Wrongful death

Key Evidence & Liability Factors

▸ECM / black box data (speed, brake application, throttle)
▸Brake inspection and maintenance records
▸Driver hours-of-service (HOS) logs for fatigue
▸Load weight manifests and cargo inspection records
▸Carrier's FMCSA BASIC safety scores — Vehicle Maintenance and Driver Fitness

FMCSA note: FMCSA regulations 49 CFR Part 393 govern brake performance standards. A jackknife caused by brake failure may indicate a violation of § 393.40 or § 393.48, opening the carrier to enhanced liability.

Arizona Fault Laws and How They Affect Your Settlement

Arizona follows pure comparative fault — you can recover even if you are mostly at fault. This is governed by Arizona Revised Statutes § 12-2505 (pure comparative fault).

Arizona Fault Rule: Pure Comparative Fault

Under A.R.S. § 12-2505, you can recover damages even if you were 99% at fault — your award is simply reduced by your percentage of fault.

Example: Your damages total $1,000,000. You are found 40% at fault. Your net recovery: $1,000,000 × (1 − 0.40) = $600,000.

Major Arizona freight corridors: I-10, I-17, I-40, US-60, SR-303 — these interstates carry the highest commercial truck traffic volume in the state and account for a disproportionate share of large truck crashes.
