What contributing factor should be shown on a crash report for a vehicle that strikes another vehicle or pedestrian legally on a highway?

In the context of a crash report for a vehicle that strikes another vehicle or pedestrian legally on a highway, identifying the contributing factor of "Failed to Control Speed" is critical. This choice suggests that the driver was unable to maintain a safe speed necessary for the conditions or the situation at hand, which can lead to collisions. Properly controlling speed is a fundamental aspect of safe driving, and when a vehicle impacts another party, it often indicates that the driver did not manage their speed appropriately.

While other factors such as driving under the influence, weather conditions, and distracted driving can contribute to accidents, in this specific scenario where the collision was classified as "legal," it implies that the striking vehicle had the right of way or was not violating any rules prior to the incident. Thus, the most relevant contributing factor in this case would be related to speed control. This highlights the importance of assessing speed in relation to traffic laws and safety protocols during incidents on the highway.
