Tips on changing lanes

I know this is gonna get flamed but here goes. I owned and operated an eighteen wheeler for over ten years. Not long for most drivers. Most posts here put the responsibility for lane change on the lane changer but nothing about the spaced out driver cruising in the blind spot oblivious to the danger he is causing.. My right turn signal was my "merging light". I would turn it on in plenty of time for following drivers to know my intentions. Lights were displayed the full length of the rig. Sometimes I would see brake nose dives and sometimes horn blasts but I would merge and hopefully wake up zombie drivers that they need to pay attention.. What the truck drivers of today have to put up with is unbelievable. I couldn't do it. They are Saints...As you may imagine, I cut the road warriors every break I can... :). Yes, I still have the same attitude..
