While a successful personal injury case involves many aspects, the overall goal is to show that the person who injured you was negligent, and that his or her negligence caused your injury.

Negligence, in a legal sense, means that someone, whether by his or her actions or omissions, failed to behave with a level of care that a reasonably prudent person would have exercised under the same circumstances. For example, a person who runs a red light at an intersection is probably negligent, because a reasonably cautious person would stop for a red light, knowing that failure to do so could harm somebody else.
