Will it make it onto this list as “LST related” rather than the usual “Not LST related”?

What’s an LST?
Longer Semi-Trailer.
“Since 2012, a trial of longer semi-trailers (LSTs) of up to 15.65 metres has taken place on roads in Great Britain (GB), enabling 30 standard UK pallets to be transported in a trailer as opposed to 26, offering more efficiency and fewer lorry journeys for commodities limited by bulk as opposed to weight. This efficiency is further enhanced by a number of operators utilising double deck trailers.
The maximum length of a longer semi-trailer plus tractor unit is 18.55 metres, marginally shorter than road train combinations allowed in general circulation in the UK and mainland Europe. Until agreement is given that LSTs can be used on international operations, they will be limited to use in the UK”
