What must a driver do before entering a highway from a private road or driveway?

Before entering a highway from a private road or driveway, it is crucial for a driver to yield the right-of-way to all vehicles that are approaching on the highway. This rule ensures that the driver does not interfere with the flow of traffic, maintaining safety for both the entering vehicle and the vehicles already traveling on the highway. Yielding allows the driver to assess the speed and distance of oncoming vehicles, enabling a safe entry onto the highway.

It's important to recognize that simply stopping or checking mirrors and blind spots does not account for the active conditions of the highway. A complete stop may not be necessary in all situations, but yielding ensures that drivers act responsibly and avoid potential collisions. Additionally, while signaling is essential, it is not sufficient on its own without yielding the right-of-way to ensure a safe merge into traffic.
