About Us

About Us

In 1969, George Prall founded the Driver Dispatch Corporation to help companies find drivers that fit their specific needs. In 1985, George’s son, Doug Prall, founded Highway Distribution Services (HDS) which took over the process of helping carriers locate drivers. Today, our company consists of over 160 drivers, five truck driving schools, a DOT regulations consulting division and a truck load carrier with over 130 trucks.

HDS Safety Services has worked tirelessly since our founding to ensure that all transportation companies have access to the services they need to ensure DOT compliance and safety. We are committed to ensuring that you have all the tools you need.

These are just a few of the services we offer:

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. Once this is completed, we will address areas that need improvement. This will be done through multiple trainings and refresher courses designed to benefit the drivers and the management team.

It is essential for your company to stay on top of the many compliance regulations DOT has for the transportation industry. When you work with HDS Safety Services, you know that your drivers are as safe as possible and that your company is protected.

Client Testimonials

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.

Dealing with HDS has been nothing but a pleasant experience from day one. Wouldn’t think of ever going anywhere else.

Keeping our company drug and alcohol free and safe is paramount in importance to us. Without the services we receive from your Clean Fleet Consortium, we could not have achieved that. With the excellent program HDS offers, reaching and maintaining that goal has been easy and affordable.

Ivan, Mike, and many others at HDS have helped me in many ways. One of the most important was assistance when I started my own business. Everyone there has always been very friendly, helpful and professional. I have always been made to feel that I can rely on everyone there for anything I need relating to my business.

We are a small seasonal operation. It is easy to forget all the CDL requirements. HDS keeps us in line.

HDS was integral in the setup of our CDL program and continues to provide great value to me and our fleet manager. The start-up of a CDL program can be quite intimidating and Ivan and his team assisted us with an audit, file set-up and continued education and communication. HDS is an essential management tool that is both cost effective and knowledgeable.

Director of Human Resources

We have valued, and continue to value, HDS’ commitment to keeping us up-to-date with the ever changing DOT rules and regulations. Thanks HDS for being a great partner in our business, saving us time and headaches in our quest of working within the legal parameters of the trucking world!
