Who Needs to Keep a Log Book

You need a DOT number in most states. Id bet yes.

 

I also do not know if you are doing interstate commerce? If so yes i believe.

 

9,000lbs gross? What are you doing driving around with an empty trailer?

 

Unless things have changed. Some states are 8500 pounds. Other states you probably won't have to worry about unless loaded.

 

As far as the Feds are concerned, no. A CMV is defined as greater than 10,000 lbs gross.

 

Combination of truck and trailer GVWR’s is most likely 10,001+ so I’d guess yes.

Scales…that is a state by state issue. Have to read the signage and decide if that applies to you or not. Most states probably not.

 

Are you this ‘for hire’ or hauling your own stuff? Like auction purchases for a farm, etc?

 

Another hotshotter that doesn't understand the rules. I'm shocked to my core.

Well at least your trying to get answers. Kinda scary that you have no clue what you weigh or could weigh.

Get this and get to reading. Has all the regulations governing truck transportation.
