What is the correct procedure for merging onto a highway?

Answer: B — Signal your intention and increase your speed to match the flow of traffic

Merging onto a highway involves a specific procedure to ensure safety and flow of traffic. The correct approach is to signal your intention and increase your speed to match the flow of traffic. This is crucial because highways are designed for higher speeds, and matching the speed of other vehicles helps maintain a smooth transition, reducing the risk of accidents. By signaling, you also communicate your intentions to other drivers, which is vital for their awareness and allows them to adjust their positions accordingly. The importance of increasing your speed while merging cannot be overstated; if you slow down significantly, it could disrupt the flow and create hazards for yourself and other drivers. Similarly, focusing only on gaps in traffic after merging could lead to dangerous situations, as it ignores the need for awareness while entering the highway. Merging without signaling is risky, as it does not alert other road users to your actions, potentially leading to collisions. Hence, signaling and adjusting your speed appropriately are essential components of safely merging onto a highway.
