When merging onto a highway, you should ________.

Maintaining the same speed as highway traffic when merging is crucial for safety and efficiency. This strategy allows for a smoother integration into the flow of vehicles already on the highway. When you align your speed with that of the vehicles on the highway, you minimize the risk of creating sudden obstacles or disruptions, which can lead to accidents. It also facilitates a more predictable driving environment, allowing other drivers to anticipate your movements.

In contrast, slowing down to let someone pass, stopping before entering, or waiting for a traffic light are not appropriate actions when merging onto a highway. Such actions could lead to confusion and increased risk, as they can disrupt the flow of traffic and create hazardous situations for both the merging vehicle and those already on the highway. When merging, the goal is to blend seamlessly into the existing flow, which is best achieved by matching speeds.
