Truck accident victims can experience life-changing injuries, medical expenses, pain and suffering, and challenging recovery periods. If you were involved in a truck accident because of the negligence of a truck driver, a skilled Arizona personal injury lawyer can help you take legal action. 

According to Arizona personal injury laws, you have the right to seek legal ramifications after a truck accident. However, you have to prove that the other party had a duty of care to you and that they breached that duty. That’s why attorneys investigate the events leading up to, during, and after the collision. 

Our truck accident legal specialists will analyze all the contributing factors and help you determine who’s liable for your accident and which benefits you are entitled to. Contact Wattel & York today for qualified legal assistance for Arizona truck accidents. Read on for more info on Arizona truck accident investigations. 

Arizona Truck Accident Investigations

Truck accident plaintiffs have to prove the defendant was negligent and that their injuries directly resulted from that negligence if they want to secure compensation in their accident claim.  Since multiple parties may be at fault, truck accident claims can be complicated. 

That’s why most claims begin with accident attorneys investigating the circumstances contributing to your injuries. Truck accident investigators will get to work immediately after the crash to preserve crucial evidence necessary to support their claims. Our accident investigators can help you find the accident’s cause, liable parties, and if drugs or alcohol were involved. 

Arizona Trucking Accident Investigations

The Federal Motor Carrier Safety Administration (FMCSA) statute 49 §390.15 stipulates that trucking companies must cooperate with accident investigations. Usually, the investigation process involves:

  • Collecting evidence
  • Consulting with experts to help strengthen claims
  • Examining the truck driver and the trucking company’s records
  • Identifying and interviewing witnesses
  • Locating and analyzing the truck’s data recorder
  • Truck inspections to determine if there is an equipment defect or failure

Commercial truck accident investigations can help determine who’s liable in a truck accident. 

Truck Accident Causes

Immediately following a trucking accident, law enforcement officials will take statements from witnesses and investigate the truck at the scene. These law enforcement officials will also check the driver. These investigations can produce evidence that determines who’s responsible for the accident. 

Investigating the trucking accident could uncover the following causes of accidents:

  • Design defects
  • Failed truck parts
  • Inadequate driver training
  • Negligent hiring processes
  • Negligent oversights
  • Negligent truck drivers
  • Overlooking safety regulations
  • Poor truck maintenance
  • Unrealistic deadlines
  • Unsafe delivery requirements

The following are some of the key factors involved in an accident investigation:

  • Accident scene investigations
  • Examining the Event Data Recorder (EDR), also known as “the black box”
  • Reviewing trucking company logs and records
  • Truck inspections
  • Witness interviews and depositions

Common Causes of Truck Driver Negligence

When a truck driver behaves negligently, the consequences can be dire. Conducting an 80,000-pound vehicle requires the highest amount of safety and caution. That’s why driving one of these vehicles impaired or irresponsibly is deemed negligent by law. 

Here are some of the most common causes of truck accidents in Arizona:


The NHTSA reported that truck driver fatigue causes up to 40% of all heavy truck crashes. That’s why big rig drivers have strict guidelines regulating hours of service and the amount of rest necessary when driving. However, the company’s pressure to meet deadlines can cause drivers to drive longer than what may be considered safe.

Drugs and Alcohol

Operating a truck under the influence of alcohol or drugs can lead to ruinous results. One study evaluated trucking fatalities from eight states over one year and found that 67% of fatally injured truckers had one or more drugs in their system. Also, 33% had detectable concentrations of drugs or alcohol in their blood. 


In 2019, nearly one-fifth of large truck drivers involved in fatal accidents had at least one speeding conviction. Trucks can be hard to maneuver and control, especially at high speeds. That’s why many states consider speeding in a tractor-trailer a negligent act.

Changing Lanes

A truck’s sheer size can make changing lanes difficult. Trucks require a much longer stopping distance than cars, and this can lead to collisions when not managed effectively. Trucks also have larger blind spots that can make changing lanes in traffic more dangerous. 

An Arizona truck accident investigation specialist can help you determine whether the driver or the truck company acted negligently in your accident. Drivers found guilty of negligence can be held liable for the resulting damages. Speak with Wattel & York about your truck accident investigation.

“Amazing people, they had my claim for about a week before they were able to get my truck totaled out. Otherwise I would have been stuck with a truck that had heavy front end damage if they hadn’t stepped in to help me. I tried to deal with my insurance company myself for over a month and that got me nowhere, all I got was a massive headache and a messed up truck. They are very professional and act quickly on your claim. I highly recommend them to anyone who is looking for help.”

“I was in an accident and decided to call Wattel and York. After months of going to a Chiropractor, I finally felt better. When it came time for settlement, the insurance company was making an offer I wanted to accept, Mr. Wattel advised against it and felt the insurance company was shortchanging me. He recommended I file a lawsuit and that will get them to cave. Well, Dave filed suit, and sure enough, the insurance company increased their offer by $4,000! I am very satisfied with how my case was handled.”

Nardeasha S.


“Wattel & York were flat out outstanding with my personal injury case. They made the process painless and kept in constant communication throughout the entire time. Any questions I might’ve had were promptly answered and detail oriented. They gave me crucial advice that I would’ve otherwise not been aware of. I couldn’t have asked for more from them. Put your trust in these guys, you won’t be disappointed. Thanks Wattel & York.”

Mattew P.


“Thank you so much for all your hard work on our behalf! Thinking I could handle it on my own, I was originally reluctant to take my accident claim to an attorney. But I am SO glad I called you instead. Your people were always helpful, pleasant and responsive at every step along the way. You represented us with honesty and integrity and made a traumatic experience as painless as it could be. And best of all, you helped us get a settlement that was fair and far more than I could ever have negotiated on my own! I highly recommend Wattel &York to anyone who has suffered a personal injury.”

“I was the passenger in a vehicle that was 'T- Boned' at an intersection in 2014. The issues of responsibility and recovery became a difficult and convoluted confusion. I really needed help. This Team at Wattel and York walked me patiently and encouragingly through difficult months, sorting through issues and finally arriving at a satisfactory conclusion. I especially want to name two great and encouraging "warriors" of Wattel and York who directed me along the way..Brian Torba and Melissa Patterson..to them and the whole team I say "Thank You" with heart felt gratitude. Sincerely, God Bless You.”

Robert G.

“Honesty. Integrity. Transparency. Partnership. Wattel & York brought all of these qualities and more to my accident case. I'd love to thank all of the team members who helped me with the process: David Guzman, who conducted the initial interview in my home, Aly Shomar-Esparza, who seamlessly guided me through paperwork and filings, Debbie Harrach, who conducted final review, paperwork revisions and scheduling, and Thomas Grisoni, who counseled me before and attended my deposition. I never felt alone during the arduous process and always knew there was a professional team looking out for my best interest. I highly recommend Wattel & York if you are unfortunately involved in an accident that was not your fault.”

Russ W.

“I was a passenger in a car that got t-boned a few years ago and got a huge gash. I didn't know a lot about lawyers, so I basically just picked one on the flip of a coin. I called Wattel and York and they explained everything, I went into the office and filled out paperwork. Got treatment on my gash over the time I worked with them, glad I did as it opened back up a couple times and bled. They did really good, got me the maximum amount of money, and made sure I was well taken care of. I was updated from time to time so that was good. The only thing I might change is I never got to thank or talk to my lawyer. I think it was because I was already used to dealing with the lady at their Glendale office so they just kept her as my point of contact. So it's okay, I'll thank them with a good review. The last thing I could say about them is months after I thought my case was over they called me and said they had another check for me for a few hundred dollars. Apparently, they negotiated with the hospital I went to after the accident. It was a nice surprise and shows they really had my interests in mind.”

Trent B.

“Wattel & York has been great for me in the past few years. I was involved in a really bad accident while I was on Active Duty in Yuma, Arizona and they have been patient with me every step of the way through a very long process. I would recommend them to anyone thank you for all your help.”

Levy G.

“Appreciate David taking the time to speak with me. He was most kind. From the front line with the receptionist, to him, the firm was a class act all the way around.”

Claire B.

“Dave Wattel represented me and my son on a Personal Injury case from a motor vehicle accident back in 2009. Jake P. handled my deposition and Dave did the Quarterbacking. The insurance company hired NFL referee Ed Hochuli's firm to try and deny our claim. But Wattel & York made it look as easy as Tom Brady on the football field. The result was more than acceptable and my son and I were compensated for our injuries and rehabilitation. Dave Wattel cares about his clients. If I ever find myself in a situation like this again, Wattel & York will be on speed dial!!”
