It's that suspension - I make a bet your DAC looks great, but once a recruiter sees "suspended license" on your application they go; "....hhmmmmmmm..." and you're right it isn't fair. What did Truckers Legal say? Did they say anything about an appeal? I've heard of them, but I don't know their policy or procedures...
On the other side the suspension will drop off, how old is it from the conviction date? What was your MVR like before this? I'd say don't give up, but you're going to have to play the systems game a bit harder.
Go through the companies on
www.everytruckjob.com and look at the companies policies on suspensions, call these companies up and ask, talk to people and learn more about the companies that interest you and then network like a #$@$@$@#@$.... the only reason that suspension or speeding ticket would hurt you if you have a great background is if the insurance program the company say it will, but policies differ company to company --- your problem is so many people are applying for jobs these days that you get lost in the pile and then when they do pick it up they see "suspended license" and automatically put it back down.
Start calling the one that have insurance policies that could accept you, and call so much you know everyone in that office by name and the number of kids they have... put your name to a character they want to hire, and that's determined and qualified to do the job.
Also see if you could meet with a recruiter in person, since you currently are driving a little, see if any of those runs might put you near a terminal you could stop by and talk with ( though don't drive up in your rig, take a taxi or something, but don't show up as the competition.. )
You can do this... we can help..
