Ch. 1 · Common Conduct

A "No U-Turn" sign prohibits making a U-turn at that location, but left and right turns are permitted.

[True / False · Medium]

Answer: ✓ True

Explanation

The Rules of the Road define "No U-Turn" as a sign that prohibits only U-turns (turning 180 degrees). Normal left and right turns to proceed are not prohibited. Remember to distinguish between U-turns and direction changes.

Hikari

If U-turns are banned, doesn't that mean all turns are banned too?

Yui

Nope, that's actually true—only U-turns are prohibited! A U-turn is a full 180-degree flip, but normal left and right turns are totally fine.

Hikari

So it's only blocking that full turnaround move?

Yui

Right! Just remember: U-turn = reversing direction. Regular turns to move forward are always okay.
