A traffic office in a haulage company has all sorts of paperwork and procedures in place to record vehicle allocations, routes, days in/off - just as a bus depot has and can be fiddled or manipulated to suit employer needs, just as it can in the PSV world.
Having systems in place in the office, shouldn't exempt any a driver of say a 10t bus or a driver of a 10t truck from requiring a tachograph, just to save a few quid.
