What is the term used to indicate that there is no traffic?

The term used to indicate that there is no traffic is "1019." This numerical designation is part of the law enforcement and dispatch communication codes, where "10-19" is commonly understood to mean "return to the station" or "proceed to less congested area," signaling that the area is clear or devoid of significant traffic issues. Utilizing such codes streamlines communication within dispatch systems, ensuring quick and effective information relay among personnel in the field.

When it comes to the other options, "TL" typically refers to "Truck Load," defined in the context of logistics and transportation, and "AL" might refer to various terms not related to traffic conditions, such as "All Clear" in different contexts. "PS" commonly denotes "Position Status," which does not specifically convey the state of traffic. Understanding these distinctions is crucial for effective communication in dispatch operations.
