I am a little confused. I see the 53' with the rear slider they say are CA legal with the slide closed to tandem. i get that. but it seems to be a 53' spread with 5' overhand off the back is about the same as a 48 fixed spread. So are the 48 fixed spread also not CA legal unless they have a rear slide which most dont?
CA Legal

To run a 53' fix spread in the Commie you'd need like a 36" pin setting & 10' of tail sticking past the last trailer axle..
You might be able to buy a kingpin permit.? Not sure, but you can get one in FL..cke, Deere hunter, truckdriver31 and 1 other person Thank this. -
got it 48s exempt ok
truckdriver31 and singlescrewshaker Thank this. -
53 foot trailer is subject to the KPRA rules, makes no difference if flat, step or van. This is why you see 53ft flatbeds with lots of rear overhang.
A 48ft trailer with a spread is exempts from KPRA. Tandems are not. -

My fleet utilizes 53' flats (and some 53' steps) with the rear most axle set back about two foot from the rear. (I'm still trying to ascertain the necessity for a 53' spread to have axles set that far back vs the placement of a normal 48' spread--Jordan Carriers' newer trailers are set up that way, too.) Anyway, we have one simple rule:
"Cali and Canada...close 'em up."
That way we'll have nothing to worry about. -
They also have a minimum of 38ft KPRA.
Single axle trailer is max of 38ft KPRA.
Pups are excluded due to trailer length restrictions.

Granted, it shows a 48' spread in the diagram, it does not specifically say spread or tandem. I only read 48' semi trailers are unlimited kingpin to rear axle.. -
The key is, 48 foot or less AND 10’1” spread.
Once you go to a tandem, then the 40’ KPRA regulation takes over.
When you go to a 53, flat, step or box, the 40’ KPRA regulation applies. That is even if you have a 10’ spread.
They make it a bit convoluted. No doubt.singlescrewshaker Thanks this. -
Scroll down and look at exceptions for STAA vehicles. 48 feet, no mention of tandems vs spread.kylefitzy and singlescrewshaker Thank this.
