How to get a JOB driving a CMV.

You left out the fact that just about everything you said is wrong. Which is the problem with absolutes.
For example we don't even have a DMV in Michigan, it's Secretary of State's office.

Compared to a total number of companies, only a small portion actually use DAC, it's not the boogieman some make it out to be. It's a private comapny selling a private service. Also, it's called Hirerite, hasn't been called DAC for over a decade.

ISSS is a made up term, at least I've never heard it before and not finding any thing in relation to trucking in a google search.
Companies can check a drivers PSP report, but it's by no means required.

 

One also needs a medical card to get their CDL. I guess that falls under what you already said though.

 

He may mean CDLIS (Commercial Drivers License Information System), although this is normally not a necessary check until the CDL is issued.

 

Would help if you used the correct term. In either case doesn't apply to the driver so it's pointless to bring it up in relation to hiring a driver.

 

Which has ZERO information that anyone would check when hiring a driver.
