Newbie Trucker with questions.

You will need to suck it up, pay your dues and put in a min of 6months to a year.
After that, as long as you stay clean - you will have tons of options.
Your speeding ticket within 3 years might limit you with some companies but I dont think its a show stopper.

By the way - for comparison...
My son went to IRAQ for 8 months. He has a newborn and is a newlywed.
He can't just pull over and call home each day or night like we can out here...
They didn't see each other for over 8 full months....it was tough.

So with all things considered, if you REALLY want to be a trucker - this is the life style your family has to support you in.
