Cyclists stay back! stickers

Actually it IS the driver's responsibility not to endanger any other road user, particularly not to kill them.

A cyclist stopped in front of this sign should be seen by the driver in the overhead mirror and probably in the wide angle mirror. The overhead mirrors to the side and front of big lorries give a view 2 metres out to the side and front of the lorry - that is the area marked out by the orange lines when the Police do 'changing places' events.
Most cyclist fatalities involving HGVs in London happen when the cyclist is hit from behind or from the side by the very front of the lorry. In almost all of these cases the cyclist has passed through an area visible to the driver, if he/she had been checking the mirrors at the appropriate time.

The myth is that blind spots cause casualties. I think that it is reasonable for a driver to be responsible for not moving his/her lorry into an area of road with restricted visibility without taking extra care to ensure there are no pedestrians or cyclists in that area.

The area more than 2 metres away from the left side of a large lorry is the most hazardous hidden area. Many drivers are unaware that this is where most victims are before a sharp turn brings the lorry across their path and runs them down. The Stay Back message is pointless for the cyclist who passes in the lane to the left of a lorry before it turns, or for the case where the lorry overtakes a cyclist then slows dramatically while cutting across their path.

far too much of 'the driver should be responsible, pedestrians and bike riders can do what ever the hell they want as the driver will make up for their lack of knowledge'.

if its so dangerous why the fuck are they going down there? perhaps because of a lack of understanding of using the road? at the end of the day you should be responsible for yourself, i dont know how thats such an odd idea. drivers more than likely are looking in their mirrors but they also shouldnt have to expect people to be in crazy places at the wrong time.

blindspots are not myths. didnt you get taught on your driving test and/or motorbike test to "check the blind spot''? im guessing you have an hgv license too, what did they say about blind spots then?
