40 foot rule on a 48 foot spread axle.

I thought the 51’s were a Canadian thing. 53’ trailers you’re restricted to a 244” tractor. Saw 2’ off ahead of the pin and it’s not a 53’ anymore it’s 51’ and you can pull it with whatever you can make 75’6” with.

 

As far as I know down here guys we’re building 50 or 51 to be able to load a loaded 40’ container on the bottom deck without the banned overhang. I am sure the western Canadian guys did it for the reason you state. Those trailers do fall under the CA KP restriction.

 

Kingpin rules only apply to trailers longer then 48.

IIRC. The number was 13 states that have kpra.

 

To write more tickets and generate revenue!!

That is all

 

It was a bone the feds threw states when the increased the length to 53'. They allowed them to effectively ban them with the kpra rule. Some states took advantage.

 

This ^^^^

NY on their infinite stupidity once cited me for KPRA on a fixed axle tridem stepdeck. Wrap your mind around that for a moment.

 

Our fixed tridem lowboy is the same way. Have to buy a annual over-length permit to pull it empty.

 

I am from California and have called and spoken to a Commercial Vehicle Enforcement officer from the CHP. Are 48 foot trailers with spread axles applicable to the 40' kingpin rule ?

Answer is no and yes. On the interstate, up to 48' trailers can have greater than 40' kingpin to center of last axle. This is because federal highways falls under federal rules due to federal funding for the interstate highway. However, on state highway, local roads, the 40' kingpin rules applies. It is at the discretion of the officer to cite the driver or not for going over 40' setting on local and state highways with a 48' trailer.

I have never gotten a ticket on my 48' flatbed trailer with spread axles over the 40' kingpin to center of last axle even though i was inspected many times on CA-99 which is a state highway.

I do have to worry that if I ever get into an accident on local roads, with the 48' flatbed trailer, a canny lawyer will use the California laws to say that my trailer was illegal on local roads due to exceeding 40' kingpin rules on local roads.

 

CA 99 is an STAA route. Those are the ones highlighted orange in your MCRA. If you go off on other roads you are subject to 65' OA and 40' KPRA.

Some municipalities used to be famous for ticketing overlength trucks as soon as they got off route. I think Tracy was one of them.
