What right-of-way rules apply when entering a highway from a ramp?

When entering a highway from a ramp, it is essential to yield to vehicles already on the highway. This is because those vehicles are traveling at higher speeds and have the right-of-way. Failing to yield can lead to dangerous situations such as collisions, as the merging vehicle may disrupt the flow of traffic or cause other drivers to react abruptly.

The design of entry ramps typically allows drivers to accelerate to match the speed of highway traffic, but yielding to established vehicles is crucial for a safe and effective merge. This process ensures that the entry is smooth and maintains the flow of traffic on the highway, contributing to overall road safety.
