A traffic question: is it legal for an eastbound vehicle on O Street to perform a u-turn at Cotner Boulevard?
Signage at the intersection indicates that left turns are prohibited. As far as I can tell Lincoln's rules of the road (PDF) treat left turns and u-turns separately; thus, a prohibition against one does not seem to affect the other. In addition, a sign (PDF) is available (R3-18) that would clearly prohibit both u-turns and left turns. Since that sign isn't posted, one assumes u-turns are allowed.
But the performance of a u-turn at that intersection is surely unsafe, isn't it? It's not the oncoming traffic that concerns me, but the trailing traffic that likely won't understand why some bozo has stopped and turned on his left turn signal when left turns are clearly forbidden.
What say you, Lincolnites? Is a u-turn at Cotner and O prohibited? Should it be?
Update: I probably ought to clarify that Tom Casady is the reason I started thinking about this.
