A **collision between a vehicle and a pedestrian** is commonly known as a **hit-and-run**. This term is specifically used to describe situations where a vehicle strikes a person who is walking, whether on the sidewalk or on the road.

- **Pedestrians** are people who travel on foot and may include those pushing baby strollers, wheelchairs, or carrying a two-wheeled cycle or moped.
- **Hit-and-runs** often result in very serious injuries for pedestrians, especially on roads outside the city where vehicles travel at higher speeds.
- To prevent hit-and-runs, both pedestrians and drivers must take precautions. Pedestrians should cross at pedestrian crossings and wait on the sidewalk before crossing. Drivers should drive at moderate speeds and pay special attention in areas with a high presence of pedestrians.

In summary, the term **hit-and-run** specifically refers to the impact of a vehicle with a pedestrian, distinguishing it from more general terms like "accident" or "collision with injuries".
