A DUI/DWI conviction will appear on a criminal background check requested by a prospective employer and may adversely affect employment opportunities in some professions, industries, and occupations—especially jobs (1) for which a commercial driver’s license (CDL) is required, (2) for which a person must operate heavy equipment or machinery, or (3) in which a person is entrusted with ensuring the safety of others (air traffic controller, police officer) or safeguarding sensitive information or data. Generally, the only way to remove a DUI/DWI conviction from appearing in some or all of such background checks is to have it expunged or sealed—which is only possible in limited circumstances.

In states in which employment is at-will an employer may terminate an employee for a DUI/DWI arrest or conviction. If the employee has a written employment contract there may be limitations on the grounds on which the employee may be terminated, and a DUI/DWI arrest or conviction may fall within those grounds of termination for cause—in other words, termination for an identified reason, and not for no reason, which is permissible under employment at will.

In Arizona, a DUI/DWI conviction is a criminal offense that will appear on a criminal background check, which can negatively impact employment opportunities, particularly in fields that require driving, operating heavy machinery, or ensuring public safety. Arizona is an at-will employment state, meaning employers can terminate employees for any legal reason, including a DUI/DWI arrest or conviction. However, if an employee has a written contract, the terms of the contract may limit the reasons for termination. Expungement or sealing of a DUI/DWI record in Arizona is not generally available, as Arizona law does not provide for expungement of adult criminal records. Instead, Arizona offers a 'set aside' remedy, which does not remove the conviction from the record but may show that the person has completed their sentence and the court has set aside the judgment. Employers may still see the conviction, but they will also see that the conviction was set aside.
