There's an active proposal for articulated lorries to be allowed a 2 metre increase in length, and the DfT and ministers are said to be inclined to agree.
The argument for is that the truck and trailer combinations on the road can already be this length, but this is an invalid argument which illustrates why technical decisions should be subject to proper technical scrutiny.
The geometry of a truck towing point compensates for the towed trailer, enabling it to follow the same path around a bend as the towing truck. The semi-trailer of an articulated truck does not do that, it cuts a corner, and a longer wheelbase increases the amount by which a corner is cut, and therefore the danger to cyclists.
Since the purpose of the longer truck application is to increase the space for light load content, the extra length may also be added by a two metre increase in tail overhang. This is an equally frightening prospect on our narrow roads, also for all other road users, since the tail swing out will be extreme at times and capable of blocking opposite lanes.
I think this 2 metre addition (nearly 7 feet) is a step too far, made worse by a haulage industry spokesman refusing to rule out a further application for greater tonnage and length in future. Of course with every step in this direction, road haulage makes it ever more difficult for rail to compete and relieve our roads of bulk freight, which is surely a desirable objective that we should not be obstructing.
