Final answer:
When entering an interstate highway, a driver must increase vehicle speed to match the flow of traffic and merge safely into a gap using turn signals, without coming to a stop on the acceleration lane unless necessary for safety.
Step-by-step explanation:
When entering an interstate highway from the acceleration lane, a driver must ensure a safe and smooth integration into traffic. This process generally involves increasing vehicle speed to match that of the highway traffic, using mirrors and checking blind spots to gauge the flow of traffic, and then merging safely into a gap in the traffic. It's vital to use turn signals to alert other drivers of the intention to merge. Additionally, drivers should not come to a complete stop in the acceleration lane unless traffic conditions require it for safety reasons. The goal is to accelerate to a safe speed that allows for merging without disrupting the flow of traffic on the interstate highway.
