Anything helps. No DUI OUI Felonie Misdomenors ever. 5Months Experience. One company preventable with pulled apart air lines. No DOT reportable accidents. No out of service or over scale.
the more you apply the better your chances. Don't be discouraged if they start shooting you down. I received about 5 rejection letters/calls before I got hired on.
The only thing about LTL is they all want a year experience before they'll look at you. Never hurts to apply anyway I suppose.
