This manuscript is dedicated to investigating the crucial connection between driver vision and road crashes, with the primary objective of identifying factors that influence visual performance and proposing effective strategies to enhance road safety. To achieve this, the study begins with an extensive literature review, delving into the significance of visual perception in driving safety. The review explores the essential visual components necessary for safe driving, such as visual acuity, field of view, depth perception, and visual attention. To gain deeper insights, the research conducts an analysis of accident data and case studies. The focus is on understanding how impaired vision, including refractive errors, visual impairments, and age-related changes, impacts road crashes. Additionally, the study examines external factors like adverse weather conditions, nighttime driving, glare, and distractions, as well as the influence of modern technologies like in-vehicle displays on visual attention and driving performance. The study particularly concentrates on heavy truck drivers, considering the potential implications of their visual issues on situational awareness and traffic safety. The findings highlight a notable prevalence of visual issues among heavy vehicle drivers, significantly affecting their driving efficiency, situational awareness, and overall traffic safety. As a crucial recommendation, the study suggests a review of the current Driving Licensing System in India. It proposes the implementation of mandatory eye testing for all applicants to obtain or renew a driving license. This measure aims to identify and eliminate drivers with vision problems, ultimately leading to improved road safety. Furthermore, the manuscript emphasizes the importance of regular vision screening and access to corrective measures for heavy vehicle drivers. Such measures can play a significant role in improving their visual function and overall driving performance, consequently enhancing road safety. In conclusion, the manuscript underscores the urgent need for effective policies and interventions to address vision-related challenges among heavy vehicle drivers. By doing so, road safety can be substantially improved, reducing the number of accidents caused by impaired vision.
