Currently there are a dozen truck manufacturers whose vehicles you will commonly see on British roads. Starting with the 18-tonne class at which an HGV (now LGV) licence becomes necessary, Patrick shows examples from each producer. He goes up to the full 38/44-tonne articulated models. This is a book for novice enthusiasts of all ages in which they will find basic information about the tractor units, the wide variety of truck bodies and the wheel conformations. The liveries of a range of carriers are also shown, though some of the vehicles are demonstrators' models. Cut-away pictures make the engineering of the trucks crystal-clear. Opposite each full-page photograph, Patrick supplies basic information about the power and performance of the vehicles. He also gives details about the companies - their nationalities and group memberships.
