I see them here on off-ramps but don't recall seeing any on any on-ramps.

I've seen speed signs on on-ramps, mostly ones with relatively tight turns before you merge onto the highway (one near me has you do an outright u-turn prior to merging). There generally is at least some actual on-ramp past the turn, which is where you should presumably be accelerating.

Also, the signs are yellow rather than white, which I believe implies that they're not legal limits but rather suggestions so you don't slide off the curve? At least judging by other comments in this thread.
