Issued in 1965, this 5¢ U.S. postage stamp promotes road safety with the message “Stop traffic accidents.” The design features a stylized red traffic light on a black and green background, symbolizing the call to halt dangerous driving behavior. The stamp underscores the importance of “enforcement, education, and engineering” as key components in traffic safety programs. It was part of a broader campaign to reduce the rising toll of road fatalities during the 1960s. A striking and modernist design makes it a memorable piece in any public service or transportation-themed collection.
