I've had a CDL in my pocket for 13 years and ran coast to coast for most of that time. I can tell you that there is an information corporation called DAC Services. Not sure what the initials stand for. And what they do is collect information about your driving career. If you fail a company preemployment, or random test. This information is put into your file in the data base. Then companies can look up your past employment history. If you fail a test it will show up. I failed a pre employment test once and it stayed on my record for 5 years i believe. So I could not get work with the better trucking companies. I had to hire on with small dangerous outlaw companies. So my strong sugestion is dont even try. Dac Services is bad doo doo.
Hypomaniac Reviewed by Hypomaniac on . MMJ and Comercial Drivers License (CDL) ? Hi all, First post, been lurking a bit though. Great forum. :) I am a legal consumer of MMJ in Colorado. I also have a Commercial Driver's License (CDL). I drove a bus at a ski area for one season, but don't currently work as a driver. There was a drug test given at the time of my initial physical, when I first qualified for my license. At the time I hadn't smoked for about 2 months, so no problem with that one. At the 2 year point I will need to take another physical. That one's Rating: 5
