The turn signal was first introduced to the public in 1938 in a Buick and described as a "
Flash-way directional signal." A few years later Buick added a self canceling feature to the signal stalk and by the 1950s most US states required functioning turn signals on all new cars. It is ironic that Buick introduced the turn signal as most often the offenders of DWS (Driving While Signaling...for miles in a straight line) are Buick drivers...typically those who were...
ahem...alive when the first signals were introduced. Drive really slow in the fast lane with your turn signal on with this
