Wherever you're getting your information from, drop them. You cannot get a hazmat endorsement with a federal felony on your record. If you were convicted of something which was only a felony under state law, but is not defined as a felony under federal law, then it is possible to apply for relief of disability, which would enable one to get their hazmat endorsement, and also to get their firearms rights back.
NOPE. A felony conviction makes you ineligible to obtain a hazmat endorsement - that's federal law. On top of that, your prospects of finding employment as a CDL driver with a felony on your record... they're less than hopeful, let's just say. You should consider a different career path.
