Final answer:
Use the acceleration lane to match the speed of interstate traffic before merging. It isn't solely about reaching 60 mph, but about safely fitting into the flow of traffic without significant disruption.
Step-by-step explanation:
When accessing an interstate, use the acceleration lane until your vehicle's speed matches the speed of traffic on the interstate and then merge safely.
In general, this means you should use the acceleration lane to increase your speed to the point where it is safe to integrate into the traffic flow without causing other drivers to slow down or adjust their speed significantly. It's not just about reaching a specific speed, but rather about adjusting smoothly with the ongoing traffic.
Some specific examples provided, such as harder on the accelerator pedal until the velocity reaches the speed 60 mph and drive the car at exactly 50 mph then accelerate to 60 mph, involve practicing acceleration and recording distances or times. However, in real-world driving, the goal is to reach a speed appropriate for safely merging rather than hitting a specific target like 60 mph.
