The whole point is that it IS 100% the truck drivers job to check all mirrors and blind spots.
All well and good in theory but I regularly drive round the E&C roundabout and you need eyes everywhere, in part for the shear volume of traffic using the roundabout but also to account for a lot of poor lane discipline by other road users. To expect truck drivers to keep a 100% lookout on all 4 corners of their vehicles whilst negotiating complex junctions like this is impossible.
