Final answer:
A formal sanction example is a court fining someone for a traffic violation, serving as a deterrent to uphold social order and ensure public safety.
Step-by-step explanation:
An example of a formal sanction would be a court imposing a fine on someone for a traffic violation. This type of sanction is used when an individual violates legally established norms, such as speeding or running a red light. Formal sanctions serve as an official response by social institutions to enforce rules and regulations. In this case, the traffic fine acts as a deterrent, discouraging the violator and other members of society from committing similar offenses in the future. The enforcement of traffic laws through such sanctions is important to maintain social order and ensure public safety on the roads.
