Three legally configured goods-vehicle combinations are being checked: a B-train, an A-train, and a heavy rigid truck towing two other trailers. For the third combination, the rear trailer has a GVM of no more than 3.5 tonnes and the whole combination has an actual gross mass below 20 tonnes. All other applicable requirements are met. All operate within the standard dimension limits in Schedule 2, with no approved dimension variation or exemption (including under a 50MAX proforma), and no load projects beyond the vehicles. What is the maximum overall length for each combination, including its load but excluding collapsible mirrors?
O loo siaki ni tuufaatasiga faaletulafono se 3 o taavale mo oloa: o se B-train, o se A-train, ma se loli mamafa mautu e toso isi taavale toso se 2. Mo le tuufaatasiga lona tolu, e lē sili atu i le 3.5 tone le GVM o le taavale toso pito i tua, ma e i lalo ifo o le 20 tone le mamafa moni atoa o le tuufaatasiga. Ua ausia isi manaʻoga talafeagai uma. E faaaogā uma i totonu o tapulaa masani o fua i le Schedule 2, e leai se suiga po o se tuusaunoaga o fua ua faamaonia, e aofia ai se 50MAX proforma, ma e leai se uta e sosolo i fafo atu o taavale. O le ā le umi atoa aupito tele o tuufaatasiga taʻitasi, e aofia ai lona uta ae lē aofia ai faata e gaugau?
20 metres for each of the three combinations under the stated conditions, not only for the B-train.
E 20 mita mo tuufaatasiga taʻitasi uma e 3 i lalo o tuutuuga ua taʻua, ae lē na o le B-train.
Taʻiala e fesootaʻi i ai
A B-train has two semi-trailers, with the second coupled to a fifth wheel at the rear of the first. An A-train has a semi-trailer towing a full trailer. The other two-trailer arrangement in this question requires a heavy rigid goods vehicle, a rear trailer with GVM no greater than 3.5 tonnes, and actual gross mass of the whole combination below 20 tonnes. These conditions do not replace other coupling, axle, mass, stability or licensing requirements. The 20-metre answer is for the stated operation: certain reduced-width loads projecting behind a rear full trailer can have a different overall-length limit, and overdimension or special-permit operation must be checked separately.
E 2 semi-trailer o le B-train, ma e soʻo le lona lua i le soʻoga fifth wheel i tua o le muamua. O le A-train o se semi-trailer e toso se taavale toso atoa. O le isi faatulagaga e 2 taavale toso i lenei fesili e manaʻomia se taavale mamafa mautu mo oloa, se taavale toso pito i tua e lē sili atu i le 3.5 tone lona GVM, ma se mamafa moni atoa o le tuufaatasiga e i lalo ifo o le 20 tone. E lē suitulaga nei tuutuuga i isi manaʻoga o soʻoga, au, mamafa, mautu po o laisene. O le tali e 20 mita e mo le galuega ua taʻua: o nisi uta e faaitiitia lo latou lautele ae sosolo i tua o se taavale toso atoa pito i tua e mafai ona iai se isi tapulaa o le umi atoa, ma e tatau ona siaki ese galuega e sili atu ona fua nai lo tapulaa po o pemita faapitoa.
