Here in CA it is legal if,
You have a CDL with doubles endorsement
The first trailer is a 5th wheel
No trailer over 28'
Combination of set not over 65'
This is all I can remember now.
Back to your original question, yes I've been pulled over once. Well my SIL got pulled over, we were both pulling two trailers. By the time I got my rig stopped and walked up to the officer that was talking to my SIL, my SIL had the officer pi$$ed off by saying he know all the rules and was legal. The one thing my SIL didn't realize was that his 5th trailer was 30' long. After I told the officer he should give him a ticket because he (SIL) is a know it all, he loosened up a bit and sent us on or way with a warning.
