In Castries, St. Lucia, in Jan. 2010, I saw this odd construction vehicle which rejoiced in a ‘Q’ suffix to its ‘T’ (Transport/Truck) code – though their T issue is nowhere near reaching Q in series, having only then reached TG.
Might the ‘Q’ indicate Special Purpose Vehicles?
I often wonder if Q in plate parlance abbreviates ‘Queer’ in its proper sense of ‘out of the ordinary/not part of the standard run’. GB has used it for international imports and exports in unusual circumstances. EAT used it as a suffix for temporary imports, (eg TAQ). Malaysia gave it to Sarawak when it struggled to split out the overlapping codes of Sabah, Sarawak, Peninsular Malaya and Singapore. Just a thought…..
