Why do collisions occur on the road?

Collisions often happen due to disruptions in the flow of traffic. This can include sudden stops, lane changes, or obstructions on the road that cause unexpected changes in speed or direction for drivers. When the flow of traffic is interrupted, it can lead to confusion and unpredictability among drivers, increasing the likelihood of collisions. For instance, if a vehicle suddenly brakes due to a traffic jam or if a lane is blocked by roadwork, following vehicles may not be prepared for the abrupt change, resulting in rear-end collisions or other types of accidents. Understanding the dynamics of traffic flow is essential for safe driving, as maintaining a smooth and predictable traffic pattern can significantly reduce the chances of collisions.
