U-turns are not legal everywhere.  Before you make a U-turn, check for No U-Turn or No Left Turn signs.  In business districts, cities and towns, U-turns are allowed only at intersections.  Never make a U-turn on a highway.  When making a U-turn, turn on your left-turn signal, stop, and yield for approaching traffic.  When the way is clear, proceed into the outside or right-hand lane traveling in the opposite direction.
