Abstract

The No Passing Zone sign (Wl0-4) was designed in 1958 for the purpose of informing the driver contemplating a passing maneuver of hazardous sight conditions ahead. This warning sign, of pennent shape design, was placed on the left side of the road so as to be more conspicuous to the intended driver. During the two year period 1959-1960, the Wl0-4 signs were erected throughout the Iowa Primary Road System.
