What do you need to do before merging onto a highway?

Answer: B — Accelerate to match the speed of highway traffic

Before merging onto a highway, it is essential to accelerate to match the speed of highway traffic. This is vital for ensuring a smooth and safe entry into the flow of traffic. Highways are designed for vehicles traveling at higher speeds, and entering at a significantly slower speed can create dangerous situations, including the risk of collisions with vehicles already on the highway. Matching the speed of traffic allows for a more seamless integration into the lane without forcing other drivers to brake or swerve. This process typically involves using the acceleration lane, which provides the necessary distance and time to build up speed and merge safely. By aligning your speed with that of the other vehicles, you enhance your safety and the safety of others on the road.
