[QUOTE 3099115, member: 30090"]Are there any blind spots on a truck?
People go on about them and you have the infamous (although factually incorrect)Tfl vid. I recall my driving days and properly set up mirrors along with the front class IV mirror meant they were not any. Certainly not when I drove. Having said this one does need to check them when pulling away from a junction.[/QUOTE]
The trouble with blind spots is that, self-evidently, you can't see them. (Or should that be self-unevidently?) We have a physiological blind spot in what we regard as our field of vision. It takes an
exercise to be able to see/not see it. Without the exercise we remain unconscious of what we can't see. There's enough visual information coming to not notice the invisible.
Beyond the physiological blind spots - sides, back of the head, high above and below, in addition to the optical nerve blind spot - there are the physical blind spots that come from having further restrictions placed on what we can see. I have the misfortune to have to do a lot of driving in a small car. I've had to make a special effort to see round what turns out to be a large pair of blind spots in the particular vehicle I'm driving, namely the pillar between windscreen and side windows. Beyond that, of course, there is the rear, the road below, the sky above, what's in front beneath the bonnet, etc, etc. Because we don't have eyes in the back of our head, we need mirrors, which can only partly compensate for the enormity of our blind spots. Sure, you can see more, but the views we get all have blind spots.
In an HGV, the blind spot problem is even more marked. Height can leave a substantial part of the road below unseen, and solid doors obscure information coming from alongside and a lower height, mirrors in artics may be adjusted for optimum vision but all this goes out of the window when turning. And as for what's behind, totally blind, if the ''If you can't see me, I can't see you'' stickers stuck on the rear of many trucks (just alongside the ''Cyclists stay back!'' stickers) are to be believed. You can't do much more than optimise mirrors to reduce blind spots but you'll still have blind spots aplenty.
