Answer :
Final answer:
It is best to A) accelerate relative to the traffic flow when entering a controlled access highway via an on-ramp and merging with traffic.
Explanation:
When entering a controlled access highway via an on-ramp and merging with traffic, it is best to accelerate relative to the traffic flow. This means that you should match your speed to the speed of the vehicles already on the highway. By doing so, you can smoothly merge with the traffic without disrupting the flow. Merging too slowly can create a hazard for other drivers, while merging too quickly can be unsafe.
For example, if the traffic flow is around 60 miles per hour, you should accelerate to a similar speed before merging.
By accelerating to match the traffic flow, you can merge safely and efficiently onto the highway.
