First Blackout Test Under New Air Raid Signals Set For Tonight

March 4, 1943

An educational test blackout to acquaint the public and CD workers with the new air-raid signals will be held this (Thursday) evening between 8:30 and 9:30 o’clock.

The first Blue Signal is to come through at 8:50 p.m. and on this, homes and buildings are to black-out, but traffic may move on low beam and pedestrians may move with caution.

On the “Red” signal at 9:10 all traffic stops, people get off the streets and sidewalks, all lights out, the blackout is total.

On the second Blue at approximately 9:20, homes and buildings remain blacked out, traffic resumes on low beam, pedestrians can move.

On the white or all-clear at 9:30, the community will return to normal.

People living in Freedom and Berrett districts are requested to clip the list of new signals in the adjoining column and save it for future reference. Under the new set-up, the Army did not prescribe an audible all-clear signal but authorized local defense councils to adopt one so long as it did not conflict with the Blue or Red. In Carroll County, a very short sounding of the siren, whistle or bell, was agreed upon as the all-clear.

After the test blackout tonight, Col. Henry S. Barrett, State Director of A.P.R. Services, announced, there will be a number of unannounced blackouts, in which the army will expect street observance of regulations. As far as he is concerned, Col. Barrett said there will be no more day-time alerts unless ordered by the Army or necessitated by actual enemy raids.
