What is the rationale for the Bridge Laws?

That is the reason. So people refer to the distances as there "bridge length". The bridge isn't a "physical" part of the equipment. It's just nomenclature.

 

California’s rule is mostly about maneuverability. Although causing more tailswing the trailer will get around right corners better with the tandems up at the 40 foot mark. If you notice in CA there are also a lot of sets of doubles. They’re popular simply because they get around better.

The only state with a KPRA rule that I can’t figure out is Florida because if you have a fixed spread axle trailer then you can buy a permit and not have to worry about the KPRA. But your standard trailer with sliding tandems has to.

 

I gotcha.

 

It helps you dodge homeless people easier.

 

I’m not sure when they made the law. But it wasn’t long ago, maybe 2010-ish, when any trailer in CA had to be 40ft from kingpin to rear axle. Then they changed it to only trailers over 48 foot. So it’s probably just something that’s been on the books long before roads and streets are the way they are now. And they probably keep it on the books because it’s an easy ticket to write and get some money.

 

We're a very inclusive bunch down here.! Plus we gotta get that whole extra $20 bucks a year from ya..

When you used to pull pots here, did you happen to notice a few intrastate guys drag'n closed tandem skateboards.? FLA allows 40k lbs with a 10% tolerance on a tandem. Spreads are pointless for the locals..
