City of Solon and Ohio Department of Transportation conducted a study to determine the effectiveness of a MUTCD non-compliant HIGH CRASH LOCATION-FOLLOWING TOO CLOSE yellow warning traffic sign. Within the context of the study limitations, the study concluded that the traffic sign made no positive impact on the number of traffic crashes. It was as if the traffic sign was invisible to the motorists.
