I understand that five axle articulated vehicle combinations were never permitted to operate at a 46 tonne maximum regulatory weight laden limit on Irish roads.
To encourage the uptake of more road friendly six axle articulated vehicle combinations, comprising of a three axle tractor unit towing an appropriate three axle semi-trailer, in April 2013 the then Minister for Transport, Tourism and Sport introduced Regulations allowing an increase from 44 tonnes to a maximum regulatory weight laden limit of 46 tonnes for such vehicle combinations. This weight limit remains in place and I have no proposals to amend it.
