To put it another way, flight levels don't exist below the transition
altitude
(18,000 Feet MSL In the US). If FL180 would be at 16950, it's not
available.

Is there a similar regulation in countries with lower transition altitudes?
On a really high pressure day, could you be cleared from 2,000ft to FL000?
