Tag for drop off area along road

Is there an established tag for a drop off area alongside a road?

These are often seen next to bus stops an look similar to passing places but exist to allow buses or other vehicles to pull out of the flow of traffic while passengers get on and off.

These are distinct from laybys and accesses to larger bus stations in that they are widened areas of an existing road rather than separate ways.

I'm sure I saw something for this once somewhere in the wiki but I'm getting nowhere in maze of public transport pages.
