This study explores the public acceptance of reduced speed limits on Greek motorways, investigating a decrease from 130 km/h to 120 km/h and 110 km/h. The inquiry is grounded on the urgent need to enhance road safety and achieve sustainable mobility, as high speeds significantly contribute to road ac-cidents, air pollution, and fuel consumption, imposing economic burdens up to €8 billion annually on Greek society. Using a meticulously designed question-naire, respondents were presented with scenarios involving different speed limits, evaluating their choices based on travel time, fuel consumption, and road acci-dent risks. The resulting data was analyzed using binary and multinomial logistic regression models. Key findings indicate that involvement in property damage crashes, past traffic code violations, gender, and income are significant predictors in accepting speed limit reductions. Notably, individuals acknowledging the cru-cial role of speed in road accidents were more amenable to speed limit reductions. The study offers invaluable insights for policymakers and stakeholders, provid-ing a nuanced understanding of public perception and acceptance of reduced speed limits, crucial for devising effective and widely accepted road safety inter-ventions in Greece.
