Abstract
A vehicle turn signal mechanism includes a lockout device in the form of an electric timer. The flashing signal is normally cancelled by a steering wheel sensor that is arranged to generate a triggering signal for an electromagnetic detent associated with a signal selector lever. The lockout device prevents the triggering signal from being generated except after the steering wheel has been retained in its straight-ahead position for a predetermined time period.
