When approaching an expressway entrance ramp on your right, how can you assist vehicles entering the expressway?

Moving one lane to your left is the correct response when assisting vehicles entering the expressway. This action provides a clearer pathway for merging traffic and reduces the chance of collisions. By changing lanes, you create additional space and time for the entering vehicles to merge safely, as they may need to accelerate to match the speed of traffic on the expressway.

It's important to be aware that the behavior of drivers entering the expressway can be unpredictable, and giving them room enhances their ability to maneuver safely. This strategy also shows cooperation among drivers, promoting a smoother traffic flow for everyone involved.

In contrast, speeding up to merge with traffic can create a hazardous situation, as it may not give entering drivers an appropriate opportunity to match the speed and merge safely. Remaining in your lane may not help integrating new vehicles into traffic and could potentially lead to dangerous interactions if other drivers are also trying to accommodate merging vehicles. Using your horn could startle drivers or escalate tensions, rather than provide support or safety.
