The street signs in Portland, Oregon are not very well designed. Most signs at intersections have the street name on a very small sign with printing on only one side. My aunt Shelley once managed to broadside a large Tri-met bus, distracted by the poor signage, desperately trying to figure out what street she was on.

Further confusing are the various large signs in Portland that read like this:

NEXT SIGNAL
Hawthorne

The major problem with such signs is that they are located about one to three blocks behind the actual intersection. Notice that little "next signal" bit? A lot of people, especially those new to the area, don't. They thusly turn prematurely, getting them hopelessly lost.
