As with any traffic control device, overuse of stop signs will cause many drivers to ignore them, creating a more hazardous situation, especially in low volume areas, such as residential neighborhoods.
Because a stop sign causes a substantial inconvenience to motorists, it should be used only where needed. Studies have shown that, sometimes, after installing a stop sign there is an increase in rear-end collisions. Also, the stop sign may cause such an inconvenience that traffic detours through residential streets, parking lots, etc.
A little known fact is that the stop and go traffic resulting from the placement of stop signs will increase carbon dioxide emissions, thereby further impacting the air quality in your area.
