They can't ask about anything but they can ask about criminal history. I've seen forms that ask about arrests, whether those led to a conviction or not. Some seem so broad that they would include traffic citations. In the US a fairly big industry exists to do background checks and pre-employment screening. Having worked in enterprise logistics for a long time, with warehouse staff and drivers coming and going all the time and mandatory background tests and drug screens, I know that employers have to carefully screen so they aren't endangering their other employees, but also that employers can show compassion and understanding and not just toss a candidate for an old conviction.
