What is the primary action to take when merging onto a highway?

The primary action to take when merging onto a highway is to accelerate to the speed of traffic. This is crucial because it helps ensure that you can safely insert your vehicle into the flow of traffic without causing disruptions or accidents. Highways are designed for faster speeds, and merging at a speed that is consistent with the surrounding vehicles minimizes the risk of collisions and enhances overall traffic safety.

When merging, maintaining a similar speed to that of the vehicles on the highway allows for smoother transitions and reduces the likelihood of forcing other drivers to brake or change lanes abruptly. It is important to utilize the acceleration lane effectively to reach the desired speed before merging onto the main highway.
