Portable changeable message signs (PCMSs) have been employed in highway work zones for decades. Results of previous research indicated that the traditional textbased PCMSs had several limitations. The advanced sign technology has now allowed the use of graphics on PCMSs, and many researchers have studied drivers' responses to graphics on PCMSs using driving simulators. This study employed driver surveys in the real-world traffic conditions to determine drivers' acceptance of using graphics on PCMSs in highway work zones. The results of driver surveys revealed that more than 87% of drivers correctly understood the work zone and flagger graphics, and over 72% of drivers believed the graphics drew their attention more to the traffic conditions. The results also showed that the majority of drivers preferred to see graphics displayed on PCMSs. This study provided valuable knowledge to government agencies and the transportation industry on how to regulate and use graphics on PCMSs in highway work zones.
