Truck Accident Lawyers
Law Firm Represents People Injured in Truck Accidents in Phoenix, Glendale, Mesa/Gilbert, Tucson, Kingman, Prescott, Flagstaff, Payson and Throughout Arizona
Truck accident cases are considerably more complex and demanding than car accident cases. Trucking cases involve volumes of federal and state safety and insurance regulations as well as industry standards that govern the trucking industry. No fewer than three federal agencies and generally two state agencies are involved in regulating trucking. In addition, local governments enact an array of traffic ordinances, rules and regulations that impact large trucks and their drivers.
This comprehensive system of laws and standards—some of which are overlapping—requires that lawyers who handle truck accident cases have the specialized knowledge and skill necessary to undertake this highly technical work. Most car accident lawyers have never litigated a case involving a large truck.
Our law firm has more than 50 years experience handling truck accident cases. We have the resources to stand toe-to-toe with the largest trucking businesses, insurance companies and governments. We are qualified and committed to the task of obtaining justice and maximum financial compensation for all our clients who are injured in accidents with trucks or otherwise.
If you or a loved one has been injured in an accident caused by a truck, we can help you. It is critical that you get the expert advice you need at the earliest possible time following an accident involving a semi-truck or other large truck. Preservation of evidence is essential to success in truck accident cases. There is no substitute for prompt and thorough investigation.
We will take care of everything for you, leaving you to heal from your injuries while we help get your life back to normal in other respects.
