In the United States, white-on-blue highway logo signs are typically used to notify drivers of food, gas, and lodging at an upcoming interchange, whereas green guide signs are used to notify drivers of the distance to upcoming cities and roadways. This study assessed driver performance and attention allocation during simulated interstate freeway driving when drivers were exposed to six-panel logo signs, nine-panel logo signs, and green guide signs. The results revealed that glance durations and fixation frequencies to green guide signs were significantly lower than they were for six-panel and nine-panel logo signs; however, no differences were found between six-panel and nine-panel logo signs. There were statistical differences between the independent variables for speed deviation and lane deviation, but the magnitudes of difference were not considered practically significant for driving safety. Overall, minor differences in sign processing time between logo signs and green guide signs did not translate into degradations in vehicle control.
