Which of the following best describes the purpose of speed limits?

The purpose of speed limits is fundamentally about enhancing road safety and managing traffic flow. Speed limits are established with the intent to protect all road users, including pedestrians, cyclists, and other vehicles, by reducing the risk of accidents. When drivers adhere to speed limits, it helps maintain a safer environment by decreasing the chances of collisions and allowing for more predictable traffic patterns.

Additionally, speed limits contribute to managing traffic flow, as they help prevent congestion and ensure that vehicles can move efficiently on the roadway. By enforcing specific speed restrictions, authorities can facilitate smoother transitions in heavier traffic situations and reduce the likelihood of sudden stops or rapid accelerations that can lead to accidents. This balance between safety and efficiency forms the core rationale behind setting speed limits on roads.
