The European Agreement on Main International Road Traffic is a treaty established in 1975 to enhance road safety and facilitate international road traffic across Europe. It aims to create uniform traffic rules and regulations, making it easier for drivers to navigate different countries while ensuring safety on the roads. The agreement covers various aspects of road traffic, including vehicle requirements, driver behavior, and road signs. By promoting standardization, it helps reduce accidents and improve the efficiency of cross-border travel, benefiting both individuals and the economy in participating countries.
