"The British Army Lorries Prior To the First World War" This 40 hp Wolseley 6 ton lorry underwent some very severe road trials in October 1905. The rout taken was from Leeds to Aldershot, a distance of 232 miles. It was pointed out that the vehicle was capable of travelling at 8 miles per hour, whereas the maximum legal speed was 5 miles an hour. It was suggested that measures be taken by which it would not be possible to put the speed lever into the fourth notch.
