Travel regulations are rules set by governments to ensure the safety and security of travelers. These regulations can include requirements for passports, visas, and health documents, such as vaccination records. They help manage the flow of people across borders and protect public health. Additionally, travel regulations may involve restrictions on what items can be brought into a country, such as food, plants, or weapons. Travelers must be aware of these rules to avoid fines or denial of entry. Staying informed about the latest regulations is essential for a smooth travel experience.
