A blue stop sign
Stop signs have always been red, as far as we know. As most everyone knows, stop signs instruct drivers to stop and wait. As with red lights, red is a color associated with making people stop and take notice or something that sets a limit.
But this blue stop sign is something we’ve never seen. It’s confusing; people don’t know whether to keep going or to stop. It’s hard to know what the intentions of this sign are. Maybe it’s a simple joke. Actually, Hawaii has a policy that signs cannot be red if they are on private property.
