It really does not matter if a company uses DAC or not. Every time you apply for a DOT sensitive job like as a truck driver companies are required by law to do a complete background check on you which amounts to the same thing as ordering a complete DAC report. Most companies also pull your MVR every year to make sure you have not had something show up since you were hired that you are not telling about since you the driver is required to report all accidents and traffic violations to your company in a timely manner.
Finding the right trucking company is like finding the right person to marry. I really comes down to finding one whose BS you can put up with and who can put up wih yours.
