How do most collisions occur at curves?

Most collisions at curves occur primarily due to excess speed on approach. When a driver approaches a curve at a higher speed than is safe for the conditions and the specific curve, it becomes increasingly difficult to maintain control of the vehicle. The momentum generated by the excess speed can lead to loss of traction, resulting in skidding or the inability to steer properly through the turn.

Additionally, when the speed is not adjusted appropriately, drivers may misjudged their braking distance or the sharpness of the curve. This can lead to either oversteering or understeering, which significantly increases the chances of a collision. Understanding the relationship between speed and curve navigation is crucial for safe driving practices, especially in varying weather conditions or when approaching unfamiliar roadways.

While distracted driving, poor visibility, and failure to signal can also contribute to collisions, the specific dynamics of curves make speed management the most critical factor in preventing crashes on these types of road segments.
