Extract from an article below about complaints re Traction engines causing delays on roads - was published in 1912 - nice to see somethings don't change.
Tractor or Traction Engine?
There continues to be no small measure of confusion in the public mind as to the differences between tractors and traction engines. The whole series of these road engines are classed together, and the smaller and more modern steam-horse is anathematized undeservedly.
The tractor is a light machine, constructed in accordance with the Motor Car Acts and the Heavy Motor Car Order, which -must weigh not more than five tons unladen, and which must. haul not more than a single truck behind it, whilst a traction engine may weight anything between 3 and 14 tons unlad-n, and may haul three ponderous trucks with an additional watercart. Thus, the tractor is never responsible for those undue delays on the road for which marey a traction engine and its train of wagons are to be blamed at times.
