Inevitable-accident doctrine is a principle of Tort law that says that a person cannot be liable for an accident that was not foreseeable and that could not have been prevented by the exercise of reasonable care. Highest degree of caution is not required. It is enough that it is reasonable under the circumstances. However, the courts rarely use this doctrine at present and rely instead on the basic concepts of duty, negligence, and proximate cause.
Inevitable-accident doctrine is also called unavoidable-accident doctrine.
