My daughter just posted this on my Facebook page thought it might be of interest to new and old alike 
I suspect all the trainers here have pics like this
Which are supposed to be blind spots? If ones with people in then some yes others a blind person can see them let alone the guide dog! ■■
I am not going to disagree with you there, there is one aspect of this photo I don’t agree with, but I was waiting for a few more comments, if the pic is saying mirror visibility, I get it (now bear in mind this is europe) so driver is sitting on the left of the lorry in a hi-viz jacket, those to the left of him are perhaps blind to his mirrors, but he would have to be blind in his left eye to not see them??
Come on nice trainer peeps help me here or have I turned French
