In a personal injury case, you must establish and prove a standard of care and prove that the at-fault party breached that duty of care. You must also prove that your injuries were a direct result of that breach of care. “Standard of care” or “duty of care” will vary depending on the type of case that you have. For example, an automobile driver’s standard of care would be to follow appropriate traffic laws and other rules that keep pedestrians, cyclists, and other drivers safe on the road.
