Which of the following scenarios best exemplifies a breach of duty of care?

A breach of duty of care occurs when an individual or entity fails to take reasonable care to avoid causing harm to others, which results in injury or damage. In the context of this question, the scenario that best illustrates a breach of duty of care is the negligent causing of a car accident.

In this scenario, a driver has a legal obligation to operate their vehicle safely. When they act negligently—such as by being distracted, speeding, or ignoring traffic signals—they fail to uphold this duty. As a result, they may cause an accident, leading to injuries or damage to others. This direct link between the negligent action and the resulting harm demonstrates a clear example of failing to meet the standard of care expected in that situation.

The other scenarios do not as directly represent a breach of duty of care. Failing to fulfill contractual obligations or misunderstanding a legal document may involve legal issues but do not necessarily relate to causing physical harm or damage that would illustrate negligence. Similarly, not abiding by business regulations may involve non-compliance but lacks the immediate connection to harm that characterizes a breach of duty of care. Hence, the example of negligence leading to a car accident stands out as the clearest breach of this legal concept.
