Which of the following is a requirement for obtaining a hardship license?

A hardship license in Massachusetts is issued under specific circumstances to individuals who have had their regular license suspended but need to drive for essential reasons, such as work, school, or medical appointments. One of the critical requirements for obtaining this type of license is having two or more operating under the influence (OUI) offenses. This requirement acknowledges that drivers with a history of OUI are more likely to need special provisions to help them regain driving privileges under controlled and supervised conditions.

The focus on multiple OUI offenses emphasizes the potential severity of their previous driving behavior, and therefore, stringent measures are put in place to ensure that such individuals can drive safely under certain guidelines. Other options like completing a driving course, passing a written exam, or being under 21 may be relevant in different contexts or for different types of licenses but do not directly pertain to the specific requirements for a hardship license in the case of OUI offenses. Thus, the correct answer highlights an essential requirement tied directly to the circumstances under which many hardship licenses are granted.
