When merging onto a highway, vehicles already present on the highway have the right-of-way. This means that drivers attempting to enter the highway must yield to the traffic that is already flowing. The rationale behind this is to maintain a safe and smooth flow of traffic, as highway speeds are generally higher and merging without yielding can lead to dangerous situations.

Merging drivers are expected to adjust their speed to fit into the existing traffic, whether that means speeding up to merge safely or finding a gap in traffic. This practice enhances road safety and prevents collisions that might occur due to vehicles forcing their way onto the highway without yielding.

While emergency vehicles have specific protocols regarding right-of-way, in the context of general merging scenarios, it's the vehicles already traveling on the highway that take precedence. Understanding this rule is crucial for all drivers to navigate highways safely and effectively.
