I often change lanes beneath lifted pick up trucks for fun
Seriously, though, I just try to make sure they see me. I'll speed up or slow down to avoid their blind spot as well as ensure that I don't change lanes into it.
Otherwise, its no different that any other driver on the road. Sedan drivers on their phone are much worse than the avg truck driver. You must have faith that the other drivers are not going to run you off the road, and you have to be prepared for when they try it
