What is a potential consequence of driving over the speed limit on interstate highways?

Driving over the speed limit on interstate highways significantly increases the risk of accidents. Higher speeds reduce a driver's ability to react swiftly in emergent situations, such as when a vehicle suddenly brakes or an obstacle appears on the road. At increased speeds, the distance required to stop a vehicle also lengthens, resulting in less time to avoid collisions. Additionally, higher speeds can lead to more severe injuries or damage in the event of an accident due to the greater forces involved upon impact.

While driving over the speed limit can also affect fuel efficiency and reaction time, the most critical consequence is the higher risk of accidents, which is a primary concern for traffic safety.
