What is the correct procedure for merging onto a highway?

When merging onto a highway, the most effective procedure is to accelerate to match the speed of highway traffic before merging. This approach allows the driver to blend with the flow of vehicles already on the highway, minimizing the risk of abrupt stops or collisions. By matching the speed of traffic, the merging vehicle can enter into a gap safely, making the transition smoother for both the merging vehicle and those already traveling on the highway.

Yielding to traffic is important, but if you do not also adjust your speed to align with that of the highway, it can lead to dangerous situations. Properly using mirrors is essential for assessing traffic conditions and ensuring that it is safe to merge. Stopping on the on-ramp can cause significant hazards as it disrupts the flow of traffic behind and can lead to collisions.

Overall, successfully merging onto a highway involves a combination of yielding appropriately and aligning speed, ensuring the safety of all vehicles involved.
