Log book required?

390.5 Commercial motor vehicle means any self-propelled or towed motor vehicle used on a highway in interstate commerce to transport passengers or property when the vehicle—

(1) Has a gross vehicle weight rating or gross combination weight rating, or gross vehicle weight or gross combination weight, of 4,536 kg (10,001 pounds) or more, whichever is greater; or

(2) Is designed or used to transport more than 8 passengers (including the driver) for compensation; or

(3) Is designed or used to transport more than 15 passengers, including the driver, and is not used to transport passengers for compensation; or

(4) Is used in transporting material found by the Secretary of Transportation to be hazardous under 49 U.S.C. 5103 and transported in a quantity requiring placarding under regulations prescribed by the Secretary under 49 CFR, subtitle B, chapter I, subchapter C.

 

Actually weight does matter, not just if you exceed the weight rating. Say you have a trailer rated and registered at 10,000 pounds, but hauling a load that is 10,500 pounds. Not only can you get an overweight ticket, you can be ticketed and put out of service for not having the proper CDL. (If, in fact you do not have a class A)

This is from Drivers
I bolded the parts that say that.

Class A: Any combination of vehicles which has a gross combination weight rating or gross combination weight of 11,794 kilograms or more (26,001 pounds or more) whichever is greater, inclusive of a towed unit(s) with a gross vehicle weight rating or gross vehicle weight of more than 4,536 kilograms (10,000 pounds) whichever is greater.

Class B: Any single vehicle which has a gross vehicle weight rating or gross vehicle weight of 11,794 or more kilograms (26,001 pounds or more), or any such vehicle towing a vehicle with a gross vehicle weight rating or gross vehicle weight that does not exceed 4,536 kilograms (10,000 pounds).

 

And the part of my post I highlighted proves that statement wrong.

Most of the time you are correct, but when a truck is over the registered weight it might kick in the need for a CDL, regardless of the actual registered weight. All I was pointing out is that sometime it does matter what the weight is. Not talking about the op of course, just in general.

As for the op, keep it under the true weight under the rating and it does not matter, that is correct.

 

Someone brought up the CDL thing, but not the OP. That wasn’t one of his questions.

 

You missed this part. Log book, medical card, license classification, etc... requirements are all based upon "whichever is greater" between the registered weight and gvwr. Overweight tickets, on the other hand, are based upon the lesser of the registered weight and the gvwr.
