Why the is the visibility minima at lower altitude lower?
I would assume at lower altitude you need better visibility since you'd expect more traffic at lower altitudes, but it looks like it's the other way around.
So my question is, why is the visibility minima at lower altitude lesser than at higher altitudes?
Generally below 10,000 feet you are restricted to 250kts.
Therefore above 10,000 feet traffic can be moving faster so one would need better visibility to "see and avoid" other traffic.
