From the cab - a HGV drivers view

I think this is on here somewhere, but this, also from a working lorry driver who is a cyclist as well, is worth spreading around the web.

Diagrams of HGV/LGV/lorry blind-spots

This is VERY useful but terminology has been confusing me:

What exactly does "undertake" and "overtake" and "nearside" mean? I think to undertake is to pass on the left, and thus overtake must mean to pass on the right?

I've only ever been a driver in the States, so things are strange enough here as it is, but to add to it, I was only ever taught the phrases "pass on the left" and "pass on the right", with it obviously being swapped over here.

Thanks for the diagram repost, Bill, I knew already not to pass on the left when I don't know how long the light has been red, and to never pass on the left if there is a chance they could be turning left, and to always watch to see if they look like they're going to turn at all, but now I will be more careful even when I know the light has just turned red, to make sure I get in front and to make sure the driver has seen me.

I know it sounds dorky, but seriously folks, Arrive Alive. I think we can steal that phrase and put it into practice for us, as well.
