Question on lane violation

[bgtg19]

I recall a clarification that officials are only to penalize the first violation where one violation causes another. I do not recall any rule change that says that there can be no double violations (that aren't simultaneous, I presume would be the argument)... and if I missed it, that is a BAD job by me! Could you (or someone) provide me with a reference; I certainly want to get it right.
