However, there are several synonyms one may use depending on the region. For example, in the United States, a traffic officer is often referred to as a traffic cop, while in the United Kingdom, the term is traffic warden. In Australia, they are known as traffic controllers. Other synonyms include traffic marshal, highway patrol officer, crossing guard, and municipal police officer. Regardless of the title, all these individuals play a crucial role in keeping roads safe and minimizing traffic accidents.
