Sure, you know what this symbol represents.  Right?  You should because we've been told this appears on the dash panel of all vehicles since the 2008 model year.  (It's been around longer, but not mandatory before 2008.)

They're called idiot lights because they're supposed  to be for idiots — that by the time you see the lamp on your dashboard, it's too late.  Idiot.  But so many consumers don't know what this lamp means — in fact 1 in 3 drivers doesn't know that when this lamp comes on, at least one of your tires has low air pressure.  Don't be an idiot, put air in your tires.
