What must occur if a person charged gives a written promise to appear in court?

When a person charged provides a written promise to appear in court, this signifies that they are acknowledging their obligation to attend the designated court session without the need for detention. The process usually allows for the individual to be released based on their signature on the citation, which serves as a temporary commitment to respond to the charges. This is a common practice known as "release on recognizance," where the individual is trusted to return for their court date without requiring bail or further conditions of release.

This mechanism helps ensure that the legal system can function efficiently by not holding individuals in custody unnecessarily while also encouraging them to meet their court obligations. Thus, the correct response highlights the effectiveness and efficiency embodied in the legal process regarding appearances in court after being charged.
