Gary Lauder designed this sign that is supposed to function in between a stop sign and a yield sign (Bill – thanks for posting this on the listserv). I'm with Mr. Lauder in spirit – I am a proponent of using more yield signs and less stop signs. There's no reason to come to a complete stop if there's no one else at an intersection.
The yield sign has the same meaning as Mr. Lauder's sign, so I don't see a need for this new sign. The idea behind a sign is that we can see the symbol and quickly determine how we are supposed to react. There is a lot of information to absorb with the proposed sign. Plus the placard below the sign is ambiguous at best. Again the rules for stop signs and yield signs are crystal clear (first come, first serve – the vehicle on the right goes first if two vehicles arrived at the same time). I like creativity, but I don't see a place for the proposed sign.
