What is the test for determining whether a motor vehicle accident is caused by accident?

Either test must be informed by the ratio of Snell v. Farrell.[11] Causation does not need to be proven with scientific precision. It is a determination that is made with a good dose of common sense and not philosophical speculation on the nature of causation.[12] Also, the negligence of the defendants need not be the sole or most important cause of injury. It will be sufficient if the negligence is only one of several causes.[13]
