The process of merging onto a controlled-access freeway requires careful execution for safe and efficient integration into the existing traffic flow. Proper technique involves assessing the speed and volume of vehicles already on the highway, accelerating to match that speed, and smoothly merging into an available gap. For instance, if highway traffic is moving at 65 mph, the entering vehicle should aim to reach a similar speed before initiating the merge.
Successfully integrating into the flow of interstate traffic mitigates potential hazards such as sudden braking, erratic lane changes, and collisions. Historically, inadequate merging techniques have been a significant factor in highway accidents. The implementation of well-designed entrance ramps and driver education programs seek to reduce these incidents. Adhering to established merging protocols contributes to overall highway safety and traffic efficiency.
