谢谢大家的讨论. 可以肯定这里不能 U TURN.  QC的解答是对的.

结论是: 如果有POSTED SIGN (本例子中那个只许直行和左转的牌子), 即使没有禁止U TURN的牌子, 也不可U TURN.

"U" Turns at intersections and between intersections

The  "U"- turn can be considered a violation as described in article 310 of  the Highway Safety Code, which stipulates that all drivers must obey  posted signs. A driver cannot do a U-turn at an intersection where a  sign prohibits it or on a road marked with a solid line since it is  prohibited to cross such a line. On the other hand, the "U"- turn is  authorized at intersections where there is no sign prohibiting it.

那么禁止U TURN的牌子用在何处呢? 一个只有红绿灯的十字路口可以直行,左右转,和U TURN. 如果只允许直行和左右转的话就加上一个禁止U TURN牌.

在只允许直行or/and左or右转的路口，排除了准许掉头的可能，为什么还要多此一举立一个禁止掉头的牌呢？——楼主朋友可以想下这个逻辑
