Which of the following represents a morale hazard?

A morale hazard refers to a situation where an individual exhibits a lack of concern for the potential loss or risk associated with their actions. This attitude can lead to reckless behavior or negligence because the individual believes that they are not personally affected by the consequences of a loss. In this context, a lack of concern for loss can manifest in various ways, such as failing to take necessary precautions to protect oneself or property or disregarding safety measures.

The other scenarios presented in the choices reflect different types of hazards. Careless handling of property and unsafe driving behavior are examples of behavior that directly increase risk due to negligence or recklessness. Not reporting a claim could indicate a lack of awareness or perhaps even a misunderstanding of the claims process, but it does not necessarily signify a moral disengagement regarding loss.

Thus, a lack of concern for loss directly captures the essence of a morale hazard, making it the correct choice in this context.
