The acceleration lane should be used to:

Answer: B — Increase your speed to match expressway traffic

The acceleration lane is specifically designed to help drivers increase their speed to match the flow of expressway traffic. When entering an expressway, it's crucial for vehicles to accelerate in this designated lane, allowing them to safely merge into the faster-moving traffic. This helps maintain a smooth traffic flow and minimizes the risk of accidents that could occur if drivers were to enter the expressway at a significantly lower speed. Utilizing the acceleration lane effectively is essential for ensuring that drivers can merge safely without disrupting the speed of existing expressway vehicles. This is why increasing speed to match the flow of traffic is the appropriate use of the acceleration lane, as it facilitates a safer and smoother transition onto the expressway.
