Ya Iknow I know----Look in the book. I have and it gets confusing. I have a 48' flat bed 10' spread and I was planning on going through MI, OH, KY, TN, GA and FL. I measured from king pin to center of rear axle and it was 42' I was pretty concerned but could not do anything about it.

I was getting loaded and was talking to another driver and he told me that 48' and under does not have to be 41' from king pin to center of rear axle Is this true? Or can some one point me to where I can get this info. I have been using a Motor Carriers' Atlas for the info I have.

Then I was just looking at the Atlas again and noticed that I read TN's rule wrong. This is the state I was worried about. It says Trailers measuring 48' to 50' from kingpin to rear of trailer require a distance of 41' or less from kinpin to center of rear axle group.

I was all set there being my trailer is 48' front to back and my kingpin is 2'


And when they say "center of a axle group" is that just for tandem set ups or would that be the center of a spread axle too?

I made the run without any problems

Thanks Mike

 

Most states have a king pin law. Some enforce it more rigorously than others.

I find that the best thing to do is get the DOT telephone numbers from the book and call the DOT directly.

That said, I beleive you are legal in the states you mentioned. IIRC, CA requires 40' from KP to center of rear axle. MD requires 42' to center of rear axle. CT is so vague it's nuts. All others to my knowledge are 41' to center of rear AXLE GROUP as you mentioned.

Also, the rules may vary depending on whether or not you are on "qualifying highways" in the "national network".

To summarize, I think you're good to go.
