“Negligence is the failure to use reasonable care to prevent harm to oneself or to others. A person can be negligent by acting or by failing to act. A person is negligent if that person does something that a reasonably careful person would not do in the same situation or fails to do something that a reasonably careful person would do in the same situation. You must decide how a reasonably careful person would have acted in [name of plaintiff/defendant]’s situation.”
