At the posted speed limit.

At a speed higher than the posted speed limit.

Explanation
Most Interstate highways have entrance ramps that allow drivers to accelerate and match the speed of traffic before merging. Entering at a slower speed can disrupt the flow and increase the risk of rear-end collisions. Always look for a safe gap in traffic before merging, and remember that vehicles already on the Interstate have the right of way. Never assume other drivers will move over or make space for you.
