North Carolina (NC) Permit Practice Test

Traveling considerably below the posted speed limit can significantly increase the chance of a car being involved in an accident on an interstate highway. This is primarily due to the potential for creating unexpected hazards for other drivers. When a vehicle is moving substantially slower than the flow of traffic, it can disrupt the normal speed dynamics, leading to situations where other drivers may have to change lanes abruptly or brake suddenly to avoid a collision. In addition to that, highways are designed for higher speeds, and vehicles traveling below the limit may not be able to integrate seamlessly with the traffic patterns, increasing the risk of rear-end collisions and other types of accidents. It is essential for drivers to match their speed to the flow of traffic, which helps maintain consistent spacing between vehicles and enhances overall safety on the road.
