Name something you learned embarrassingly late in life.

Yeah I knew that much.  I thought there might be some quirk I didn't know about.  

 

Speaking of Interstates, one thing I learned in adulthood is that on Interstate exit signs, the positioning of the small rectangular sign at the top of the bigger sign tells you if your upcoming exit is to the left or to the right.  

 

 

We know the lane for Exit 11 is to the right because the small sign is atop the right side of the larger sign.

 

And here, Exit 13 is to the left.

 

 

 

 
The arrows peeling off to the right and left are big clues, too

The signs further from the exits often don’t have the arrows.  I looked for examples without the arrows but didn’t see any on  Google.

Did you know that 2 digit highway numbers signify a highway that spans several towns and cities and 3 digit highways are the local connectors to those highways. 

It's why you see interstate 290 connects to interstate 90 or 291 connects to interstate 91 or 495 to 95 etc.

 

haha, no idea. thanks!
