When a driver from Illinois suddenly veers into your lane for no reason, with no turn signal whatsoever. Usually performed at high speed, and when no other cars are in the vicinity.

The idea to teach the concept of "turn signals" has been floated through years in Illinois driver's ed schools, but nothing serious has come of it.

Outside of Illinois, it is most often seen by Wisconsin and Indiana residents due to the prevalence of FIBs.

A Taos Turn Signal occurs when someone turns on their turn signal either during or after the turn for which it regards. Although this action is common everywhere, it happens a lot in northern New Mexico, and has become somewhat of an inside joke among residents around New Mexico to call a late Turn Signal a Taos Turn Signal.
