Also known as a turn signal on an automobile
, which, although is a useful tool in alert
ing the public to your turn
ing actions while driving, especially in cases where your turn affects the flow of traffic
, seems (by most drive
rs) optional and almost unnecessary in driving today. I would need several more hands to count on them the number of times someone does not use his/her blinker when it should be used, during a single drive home from work.
