For example, drunk drivers might contend that they drove their car to get away from being kidnapped (cf. North by Northwest). Most common law and civil law jurisdictions recognize this defense, but only under limited circumstances. Generally, the defendant must affirmatively show (i.e., introduce some evidence) that (a) the harm they sought to avoid outweighs the danger of the prohibited conduct they are charged with; (b) they had no reasonable alternative; (c) they ceased to engage in the prohibited conduct as soon as the danger passed; and (d) they themselves did not create the danger they sought to avoid. Thus, with the "drunk driver" example cited above, the necessity defense will not be recognized if the defendant drove further than was reasonably necessary to get away from the kidnapper, or if some other reasonable alternative was available to them.
