December 15, 1954, is S-D Day. On this day, every American is asked to do what he should do every day— try his utmost to prevent all traffic accidents. This all-out one day effort is planned in the hope of dramatically highlighting the problem of our frightening traffic accident toll and to enlist continued public cooperation for traffic safety. S-D Day, the culmination of a 30-day traffic safety campaign, was planned by the President's Action Committee for Traffic Safety, in line with President Eisenhower's firm conviction that concerted public effort can result in a drastic decrease in deaths and injuries on the highway. The traffic safety group has asked the cooperation of physicians because of their long interest in the problem. Pedestrians and drivers will be asked to follow these safety procedures: 1. Observe the letter and spirit of all traffic regulations. 2. Be courteous to every driver and pedestrian.
