Which vehicle action is recommended to help keep traffic flowing smoothly?

Yielding when it helps prevent crashes is essential for maintaining smooth traffic flow. This action not only enhances safety but also contributes to the overall efficiency of the roadway system. When drivers yield appropriately—such as allowing merging vehicles into a lane or giving way at intersections—they help reduce potential conflicts and bottlenecks, ensuring that vehicles can continue moving without unnecessary stops or delays.

In contrast, actions like driving faster than the speed limit can actually disrupt traffic flow and create dangerous situations. Yielding only to pedestrians overlooks the need for cooperation among all road users, including other motorists and cyclists. Always using the left lane for passing can lead to traffic blockages, especially if slower vehicles occupy that lane unnecessarily. Therefore, the practice of yielding when it aids in crash prevention stands out as a key strategy for promoting not just safety but also the smooth functioning of traffic as a whole.
