The concern for mental overload from warnings has been considered over a longer period of time, even though; warnings continue to be added in vehicles. Both warnings and icons are being tested for understandability but perceptions of the importance of each specific warning and its placement in the driving compartment seems to have had lesser importance in research. Such as, too much visual information presented to the driver or confusing warnings has showed to cause overload and, hence, reduce the driver’s ability to perform safely. A dilemma the automobile industry is facing today is how to expand the ways visual information via warnings can be presented to the driver without increasing the cognitive workload, which, in turn, increases the risk for distraction. The aim of this study was to investigate the effects of warnings placement on the drivers’ ability to respond to them while maintaining safe driving in normal driving conditions. Twenty respondents drove a fixed based high fidelity driving simulator though 15km of light to moderate traffic in both rural and urban areas while responding to warnings. Ten respondents received warnings in both the head-up display (HUD) and head-down display (HDD) simultaneously while the other respondents received the same ten warnings in one of the four displays: HUD, HDD, infotainment display (IF), and center-stack display (CS) in the same traffic situations but in only one of the four placements at a time. The respondents’ response times to the warnings (via focal vision), their gaze patterns, average speed, maneuverability, and their own subjective responses were measured. The results showed that there were no significant differences between the baseline and experimental runs due to the simple nature of the tasks while significant differences were found in the response times regarding the four placement design. Warnings for serious failures and those pertaining to the vehicles mechanical operation were preferred to be placed in the HUD while warnings for maintenance and service along with reminders were chosen to be placed in the HDD. Response times and driving was perceived to be better when using the HUD while the CS was considered too far away to be looked at for warnings.
