[PRCo] Re: 42/38 on Smithfield Yellow-Green Light

[Herb Brannon]

Thanks to "our friends", the US Government, all signals everywhere in the
United States are all alike these days. It all started with the Uniform
Traffic Control Act of 1973. It took a couple decades to make the country
monotonous. Nowadays all the stupid people only have to learn one set of
rules. Heaven forbid that any certain area of the country should have
something which might give it a noteworthy difference (aka character) from
any other area. At one point I did post the newest federal manual on traffic
control devices and signs on The List. It should be somewhere in the list
archives. *Under these uniform rules traffic signals may be mounted either
horizontal or vertical. *
Not only did Canton, OH have the two-tier signals with only red and green,
but New Philadelphia, OH had three-tier signals with only three bulbs. One
street had, from top to bottom, red, yellow, and green lenses while the
cross street had, again from top to bottom, green, yellow and red (on the
bottom) lenses.
