Which of the following is classified as a dual offence?

A dual offence is typically one that can be prosecuted as either a summary offence or an indictable offence, depending on the severity of the circumstances and the discretion of the prosecution. Common Assault fits this classification well because it can be handled in both ways. Depending on the severity of the assault and the context in which it occurred, it could lead to either a summary conviction (which carries lighter penalties) or an indictable conviction (which is more serious and can involve harsher penalties).

In contrast, the other options generally do not have the flexibility in their classification as dual offences. Threatening Behavior, for example, is typically addressed as a summary offence, while Driving without due care may also be treated primarily as a regulatory issue. Public Intoxication is usually managed similarly, often being classified under local bylaws or minor offences without the option for dual prosecution. Therefore, Common Assault stands out due to its dual nature in the legal framework.
