Truck Accident Laws in Arizona

Commercial truck accidents in Arizona are governed by a combination of federal FMCSA regulations and Arizona state law. Understanding both layers is critical to building a successful claim against a negligent trucking company.

Major Truck Corridors in Arizona

The following highways in Arizona carry the highest volumes of commercial truck traffic and are therefore the site of the most serious crashes:

• I-10 — A major commercial freight corridor through Arizona
• I-17 — A major commercial freight corridor through Arizona
• I-19 — A major commercial freight corridor through Arizona
• US-60 — A major commercial freight corridor through Arizona

Federal FMCSA Regulations That Apply

Regardless of which state an accident occurs in, all commercial trucks operating in interstate commerce are subject to Federal Motor Carrier Safety Administration (FMCSA) regulations. When a trucking company or driver violates these rules, it becomes powerful evidence of negligence:

• Hours of Service (HOS): Drivers are limited to 11 hours of driving within a 14-hour window and must take a 10-hour rest break. Violations are a leading cause of fatal truck crashes in Arizona.
• Electronic Logging Devices (ELDs): All commercial trucks must use certified ELDs to record driving time. Logbook manipulation is common and must be investigated.
• Drug & Alcohol Testing: Trucking companies must conduct pre-employment, random, and post-accident drug testing. Many accidents reveal these protocols were bypassed.
• Vehicle Maintenance: Federal law requires detailed pre-trip and post-trip inspection records. Brake and tire failures are frequently the result of deferred maintenance.
