The determination of which vehicle proceeds first when joining a high-speed, limited-access highway is a common point of confusion. The general principle dictates that vehicles already traveling on the freeway possess the priority. Merging vehicles, entering from an on-ramp, are expected to yield to existing traffic flow. For instance, a driver on an on-ramp should adjust their speed to safely integrate into gaps in the freeway traffic, rather than forcing their way into a lane.
Adherence to yielding protocols during freeway merges is paramount for maintaining smooth traffic flow and preventing accidents. Prioritizing existing freeway traffic ensures consistent speed and reduces the likelihood of sudden braking or lane changes, both of which can lead to congestion and collisions. Historically, inconsistent merging practices have been a significant contributor to freeway accidents, highlighting the importance of clear yielding behavior.
