SUMMARY:?Our safety standard on theft protection specifies vehicle performance requirements intended to reduce the incidence of crashes resulting from theft and accidental rollaway of motor vehicles. As a result of technological advances in the area of theft protection@ the terminology used in the regulatory text of the Standard has become outdated and confusing with respect to key-locking systems that employ electronic codes to lock and unlock the vehicle@ and to enable engine activation. This final rule amends and reorganizes the regulatory text of the Standard so that it better correlates to modern theft protection technology and reflects the agency??s interpretation of the existing requirements. The new language does not impose any new substantive requirements on vehicle manufacturers.?
