Thank you. I had hoped to find an international sign that showed a figure almost like a question mark, with an arrow head at the end pointing back at you. This would be perfect for right hand traffic. Perhaps a mirror image for left hand traffic.
Of course I guess we could make one up. I wonder what the process is to get a sign recognized by the international community.
Preferrably the sign would be in a blue diamond field with a white directional arrow. Or would it be a yellow warning sign because of the potentially tight turn around? (Of course, no tandum trucks.)
I did not see a U-turn sign, although I think there are such animals. Maybe that would work.
Preferrably the sign would be self explanatory with no lettering (cul-de-sac is so long at 10 characters).
