In developing countries where comprehensive policies addressing the environmental impact of ELV have been implemented, this mixed-methods study examines the complex relationship between knowledge and social acceptance of ELV policies in developing countries. The study integrates a quantitative survey with 150 participants and a qualitative phase featuring indepth interviews with 15 individuals. The quantitative survey explores participants' understanding and acceptance of various aspects of ELV policies, revealing diverse knowledge levels on environmental, economic, public health, safety, and technological dimensions. Notably, there is a solid willingness to comply with these policies, highlighting their perceived importance in safeguarding environmental and public health. The qualitative phase delves deeper, uncovering factors influencing social acceptance, such as limited awareness, positive attitudes, and considerations related to economic, safety, and health concerns. This study emphasizes the critical role of knowledge in shaping the social acceptance of ELV policies, demonstrating that an informed public is more inclined to have favorable attitudes and greater acceptance. By blending quantitative and qualitative insights, we obtain a holistic understanding of the interplay between knowledge and social acceptance concerning ELV policies. This comprehensive perspective is invaluable for policymakers and stakeholders, underscoring the necessity of well-informed strategies to boost public comprehension and acceptance of ELV policies. The findings indicate that effective communication and education initiatives could significantly enhance the implementation and effectiveness of ELV policies in developed nations, suggesting a pivotal role for targeted educational and awareness campaigns in achieving policy goals.
