If you work for a good place I would assume that they do check they have to otherwise you could have alot of legal issue with bad drivers and companies do not want to hire new drivers that would cause alot of problems. I haven't worked in that field, but common sense says that IF it is a good company that values their employee then they wouldnt hire just anyone they would check to make sure you dont have a bad driving history. I assume as long as you dont have a BAD history just a ticket here and there things should be fine.
