How can you prevent an expressway emergency during merging?

Merging without stopping is critical for preventing an expressway emergency because it maintains the flow of traffic and minimizes the risk of collisions. When you approach a merging area on an expressway, it's essential to adjust your speed to match that of the vehicles already on the highway. This helps create a smoother transition and reduces the chance of an abrupt stop or slowdown, which can lead to rear-end collisions.

Stopping before merging can create dangerous situations as it disrupts the normal flow of traffic, increasing the likelihood of being hit by faster-moving vehicles. Merging slowly might not be effective either, as it can cause delays and confusion for drivers behind you. Signaling your intentions to merge is important, but it alone won’t prevent emergencies if the actual merging process is not executed properly by aligning your speed with the ongoing traffic. Hence, merging without stopping while ensuring proper signaling is the safest and most effective way to prevent emergencies during the merging process.
