THE DETECTABILITY OF TWO SLOW VEHICLE WARNING DEVICES

THIS STUDY COMPARED THE DETECTABILITY OF THE SMV (SLOW MOVING VEHICLE) EMBLEM AND THE RED FLAG. THE MEASURED DETECTION TIMES WERE EXPRESSED IN MEAN NUMBERS OF SECONDS FROM THE REAR OF A FARM WAGON. DETECTABILITY OF THE SMV EMBLEM AND RED FLAG WERE COMPARED FOR SELECTED DEMOGRAPHIC VARIABLES. SUBJECTS DETECTED THE SMV EMBLEM AT A SIGNIFICANTLY GREATER DISTANCE THAN THE RED FLAG REGARDLESS OF SEX, AGE, OR PLACE OF RESIDENCE. THE DIFFERENCE IN MEAN DETECTION TIMES OF THE SMV EMBLEM AND RED FLAG WOULD ALLOW MOTORISTS TRAVELING AT 50 MPH APPROXIMATELY 270 FEET OF ADDITIONAL WARNING WHEN APPROACHING THE REAR OF A FARM VEHICLE DISPLAYING THE SMV EMBLEM. /HSL/
