About HDS Safety Services

Drug and Alcohol Testing Programs
We operate one of the largest random drug and alcohol testing consortiums in the State of Arizona for both regulated and non-regulated drug screening.

HDS Safety Services provides federal and state audits of your company’s entire safety program.

Driver Qualification and Pre-Employment Screening
In addition to helping your company implement good hiring practices, we build, audit and maintain required driver qualification files. This includes ensuring the inclusion of background checks, motor vehicle reports, drug tests and physical exams.

Compliance and Safety Training
Our knowledgeable professionals will identify strong points, effective policies and systems and address areas that need improvement. This will be done through multiple training and refresher courses designed to benefit the drivers and the management team.


In 1969, George Prall founded the Driver Dispatch Corporation to help companies find drivers who fit their specific needs. In 1985, George’s son, Doug Prall, founded Highway Distribution Services (HDS) which took over the service of helping carriers find drivers that fit their specific needs. Today, our company consists of over 200 drivers, four truck driving schools, a DOT regulations consulting division and a truck load carrier with over 200 trucks.

I have been using HDS services since 2002.  Mostly it was the drug, then alcohol testing consortium.  They have always been knowledgeable about the testing and making sure it was done correctly and my paperwork in the office was correct.  More recently, with all the changes in DOT paperwork, and the larger driver files I have to have, HDS has always been able to answer my questions to make sure my driver files are correct.  I would recommend Ivan and Marie to anyone needing this type of service.
