Pininfarina - here's a straight answer.
If you are a Trinidadian national (with a Trinidadian licence), you join the line unless you know someone.
If you are a Caricom national (with a Trini or Caricom licence), you join the line behind the Trinidadians.
If you are neither of the above, they won't even let you into the line.
Hope that clears things up.
