Final answer:
When entering an interstate highway from the acceleration lane, you must accelerate, check your blind spots, signal, and merge gradually into the traffic lane.
Step-by-step explanation:
When entering an interstate highway from the acceleration lane, you must accelerate to match the speed of the traffic on the highway. This ensures a smooth merge and minimizes the risk of accidents. You should also check your blind spots and use your mirrors to ensure it is safe to merge. Finally, you should signal your intention to merge and gradually move into the traffic lane.
