From The Indianapolis News, Monday, September 19, 1921: This week’s “Walk Right, Drive Right” campaign for the elimination of street mishaps began today. Finding that many accidents are caused by faulty brakes and signals, the board of public safety has detailed ten police officers at sites around Indianapolis to test the brakes and signals on cars, and the drivers’ knowledge of traffic rules. A sticker will be placed on the windshield of all automobiles passing the tests.
