Ramadan fasting leads to significant alterations in daily routines, notably disrupting sleep schedules. Such changes can impair cognitive functioning and driving performance, thereby increasing the risk of accidents. This study investigated the relationship between sleep quality and driving performance among Indonesian drivers during Ramadan. A total of 273 Indonesian drivers who observed Ramadan fasting participated in an electronic survey. The survey assessed sleep behaviors, subjective sleepiness across different times of day, and self-reported driving performance. Data were analyzed using descriptive statistics, Analysis of Variance (ANOVA), and Pearson correlation tests. Participants reported increased daytime sleepiness during Ramadan, with the highest fatigue levels observed around noon. Poorer night-time sleep quality and suboptimal nap quality were significantly associated with elevated aggressive driving behaviors and reduced driving performance. Although increases in accidents and traffic violations were modest, they highlight the public health importance of sleep management during fasting periods. Ramadan fasting negatively affects sleep patterns and driving behavior among Indonesian drivers. Interventions promoting sleep hygiene and strategic napping could substantially enhance driving safety during Ramadan. Future research should incorporate objective performance assessments to strengthen and validate these findings.
