If you are traveling in the right lane of an interstate highway, what adjustment must you make when other vehicles are entering the highway?

When you are traveling in the right lane of an interstate highway and other vehicles are entering the highway, the most appropriate adjustment is to merge into the left lane when it is safe to do so. This action helps to create a smoother flow of traffic and allows merging vehicles enough space to enter the highway without having to immediately adjust their speed significantly.

By moving to the left lane, you provide the entering vehicles the opportunity to accelerate and merge effectively, reducing the risk of traffic congestion or abrupt stops. Maintaining a safe distance and ensuring that you do not cut off merging vehicles contributes to overall highway safety and traffic management.

While speeding up to merge might seem like a way to create space, it often leads to dangerous situations as it could cause sudden changes in speed. Remaining in the right lane without making any adjustments could impede merging vehicles, possibly resulting in awkward or unsafe merging maneuvers. Honking your horn is not a recommended safety measure for this scenario; it may be perceived as aggressive and does not address the issue of creating space for merging traffic.
