The aim of this study was to investigate the effects of redundant driving information while conducting simple vs complex tasks via instructions presented simultaneously from the Head-Up Display (HUD) and Head Down Display (HDD) placements in normal driving conditions. Twenty respondents drove a fixed based high-fidelity driving simulator through 15km of light to moderate traffic in both rural and urban areas while responding to instructions. Ten respondents received ten warnings to respond to by pressing a button while the other ten respondents received ten instructions to conduct tasks in the center-stack area of the simulator. These tasks varied in difficulty from turn on CD player, to dial a given telephone number. Driving performance was measured via response time, gaze patterns, average speed, and maneuverability. Cognitive workload was assessed with the Driving Activity Load Index (DALI). The results showed that there were no significant differences between the baseline and experimental runs for the warnings due to the simple nature of the tasks while significant differences were found in the average speed and deviation from speed limit. The respondents rated the complex tasks as having a greater visual and temporal demand in relation to the simple tasks. The HUD was almost exclusively used by the respondents for driving information and stated that it was fitting for warnings and primary driver information.
