Tourism business plays crucial part in the economies across the globe. In addition to providing a range of chances for generating income, tourism also creates a number of problems for society as a whole. The development of sustainable tourism destinations may be hampered by a number of careless tourist behaviors, such as littering, using unhygienic facilities, smoking in public places, fighting over seats, chatting loudly, capturing pictures without consent, plucking flowers, etc. Understanding the factors that contribute to ethical tourism practices and the causes of irresponsible tourism behavior is equally important. Therefore, for nations hoping to boost tourism's competitiveness, promoting responsible travel may be a top priority. It is believed that government policies can have a significant impact on how tourists behave responsibly. This study aims to explore the factors that influence tourists' responsible travel behaviors. The purpose of this study is to examine how attitude, subjective norm, and perceived behavioral control relate to responsible tourism behavior. A theoretical framework utilizing TPB is presented in this paper. The study uses government policy as the moderating variable to assess the relationship between attitude, subjective norm, and perceived behavioral control. A questionnaire was used to collect data from 421 respondents using convenient sampling, and PLS-SEM software was used to analyze the results. The data reveal that government policy as a moderator doesn’t have any meaningful effect in the relationship between attitude, subjective norms and perceived behavioral control. The results of this study will help academics and practitioners create more effective plans to enhance tourist behavior in the locations.
