I'm sure we all know what a "u-turn" is. However, people seem to go from the top of the U. Wouldn't an "n-turn" make more sense, because driving logistics force you to go in more the shape of a lowercase "n", from your perspective.

    It's in the shape of a "U" from your perspective AFTER you finish the turn. Sep 8, 2014 at 19:41

The shape of an "N" is ambiguous (upper or lower) but the shape of a "U" is not.


Most critical traffic instruction signs are written in capital letters, such as

  • STOP
  • MERGE RIGHT etc.

This is so that it can be clearly seen from a distance.

As mentioned by Chris Sunami upper case "u" is still "U" making it unambiguous, whereas n becomes N which is ambiguous, irrespective of the sign looking like a "n" however in written form it is U.
