Background: Driver drowsiness is one of the most significant causes of traffic accidents worldwide. As accident rates increase, scientific studies in this field have grown. Objectives: This study examines trends in research related to risk factors and outcomes of driver drowsiness, providing comprehensive insights into the current state of science and existing gaps through performance, network, and content analyses in a bibliometric review.Methods: Articles with relevant keywords were searched and extracted from the Web of Science database. After initial screening, the bibliometric R software was used for performance analysis, and VOS viewer was employed to analyze and visualize key terms and create scientific maps.Results: The analysis included 369 articles from 1971 to 2023, with a growth rate of 4.44%, written by 1,363 authors from 55 countries and 548 institutions. Most articles were published in English (363), with single articles in Turkish, Spanish, Russian, Portuguese, German, and French. Based on document count, citations, and normalized citations, the USA, Australia, and Sweden ranked first, second, and third, respectively. There were 108 scientific collaborations between countries, with the USA having the highest total link strength (102). France and the Netherlands ranked second and third with total link strengths of 21 and 19, respectively. New Zealand and Fiji had the highest collaboration (six joint articles), followed by Sweden and France with five joint articles. Conclusion: This study highlights the growing research trend in driver fatigue and related accidents. Since fatigue seriously impacts road safety, further research is essential on fatigue prevention and utilizing modern technologies for the simulation and detection of driver fatigue risks.
