How fast should you be going when you merge onto an interstate?
The rule
Before you pull onto the highway, speed up in the acceleration lane until you match the traffic, then merge into a gap.
Speed up in the lane beside the road until you match other vehicles, then merge into a gap in the traffic flow.
From the SCDMV Driver's License Manual, page 7-14. This question is our own wording of that rule. The handbook and the DMV have the final word.
