Which definition best describes Traffic in roadway safety terms?

• A. All pedestrians, ridden or herded animals, motor vehicles, street cars, and other conveyances, used either singly or together, while using any highway for travel.
• B. The portion of a roadway used solely for vehicle travel.
• C. The surface of a street that is dedicated to pedestrians.
• D. A device used to move people on a highway.

Answer: (A)

In roadway safety terms, traffic means every user moving on or using the highway to travel. The best definition is the broad one that includes pedestrians, animals, motor vehicles, streetcars, and other conveyances, whether they’re traveling alone or together. This inclusive view is essential because safety rules and design must account for all who share the road, not just motor vehicles. The other options describe narrower ideas—for example, just the part of the road used by vehicles, or the area set aside for pedestrians, or a device used to move people on the road—which don’t capture the full concept of traffic as all road users.
