It’s a little more complex depending on location and number of lanes, but in general yes even if it means going above the speed limit, you must not impede the flow of traffic.
Where I’m at it’s only illegal to go slower than the flow of traffic in the left (passing) lane. This does apply to people doing more than the speed limit. If you are going the speed limit you have to rock the farthest lane to the right so as to not impede traffic.
Surely this isn’t true, legally, if you’re traveling at or above the posted speed limit.
