These signs were dropped from the Manual on Uniform Traffic Control Devices in 1961, and have not been reintroduced in any of the subsequent manual. It is important to be aware of the following information; the Town of Hamden has not used "Children at Play", or "Slow Children", etc. signs since the mid-seventies, the logic being that they have no regulatory, or enforcement value, and they lose their warning value because every street qualifies for children signs by virtue of children, grandchildren, or visitors. If every street has a "Slow Children" sign, the sign becomes meaningless, like sky overhead.
The Traffic Department has followed a policy of posting warning signs for all schools and playgrounds. 25 Mile Per Hour Speed Limit signs are used in all other areas where children are present; this gives the Police Department the authority to arrest violators, rather than a non-enforceable warning sign.
