What should you do before merging onto a highway?

Before merging onto a highway, it is essential to increase your speed to match the flow of highway traffic. This helps ensure a smooth and safe entry into the highway. Highways are designed for higher speeds, and merging at a similar speed helps prevent dangerous situations, such as collisions or abrupt stops.

Merging at a speed that is too low can cause unexpected disruptions in traffic and increase the risk of accidents, as other drivers may not anticipate a vehicle slowing down. By adjusting your speed appropriately, you can merge safely while being aware of other vehicles' movements and maintaining the overall flow of traffic.

While signaling intentions and checking for traffic are also important aspects of merging, increasing speed is the critical action that enables the merging process to occur safely and smoothly.
