Can you name one?
IMO opinion the rules are not that confusing if they have been read and accepted. It seems to me that they are most confusing to people that have not read them and/or are trying to bend them so that they are not included by them.
That is true for the most part except for the "once you break 26K in combination, you need a CDL" part. Breaking the 26k threshold is only half the equation. 20k trailer + 7k truck = CDL. 20k truck + 7k trailer = No CDL.
Duffster, your right on the above counts, I stand corrected. However, I know people who have been ticketed for having a trailer over 10K, right or wrong, it happens.
