Don't Hang Out In The Left Lane

Roads have multiple lanes so that slower traffic can keep right, and faster traffic can pass them in the left lanes.  It's a very simple concept, however, a day doesn't pass when I don't get stuck behind some idiot who decides to go for a Sunday drive in the left lane.

GTF out of the left lane if you're going to drive slow!  Move into the lane that has been designed for you - the RIGHT lane.  The Florida Outdoor Advertising Association has got it right:  don't hang out in the left lane!
