Stop signs can cause traffic back-ups.
Speed bumps delay fire trucks and ambulances.
And there are only so many traffic cops to go around. Residents could post the signs in their yards to remind drivers to slow down. Blough said there are about 500 traffic collisions in Encinitas each year. The city has tried other measures to slow traffic, but each has consequences. Engineers say they don't like to use stop signs to control speeding because drivers are less respectful of signs used that way, leading to rolling stops that can cause collisions.
