Signs Good vs. Bad Many towns throughout Maine are somewhere in the E-911 process. Eventually, every town and city will be erecting new street name signs.
Tourists rely on signs for guidance to hotels, homes, etc.
The signs should also be reflectorized for maximum visibility to emergency vehicles in the worst rain, snow, or fog conditions. However, for local roads with speed limits of 25 mph or less, the letters should be at least 4 inches high and the ST or AVE supplementary lettering should be at least 2 inches high. OR whenever an existing sign is replaced within the next 15 years. Each community must decide if and when it adopts the new recommended standards for letter size. Height of the bottom of the sign at the side of a road in rural areas shall be at least 5 feet.
