Possible weekend job with trucking?

Actually no. But that has to do with day trading laws, not fmcsa laws.
Basically stock trading isn't compensated work as per stock trading laws, so definition 9 doesn't apply.
There was a thread about this here awhile ago with all the specific laws mentioned....

 

What's even worse, it could be interpreted as that hobby you have on the weekend as work.
Say you enjoy woodworking and make gambling tables, or even those wooden wells for the front yard. If you sell them then now you are being compensated for your work...

 

Not realy gray. The on duty definition was already posted. The guidance applies to parts 1-8 as those parts don't address compensation. They simply address "work.". Part 9 specifically states "all compensated time" for a non motor carrier.
Basically it's talking about stuff like detention pay where one is paid just to be somewhere.

 

Google Driver Leasing Companies, that's what the companies that supplied temporary drivers to my last company were called. I think one was called Driver Solutions an another was TransForce.

 

I think if you are trading for your own/family account it's not work, but if you were trading for another company it would be "compensated work" assuming you get paid or get commission on what you trade.

 

ANY work you do for compensation counts against your DOT 70 hour limit. It doesn't matter if you are working as a cashier, teacher, or MMA fighter. ANY work. There are a few trucking companies that pay salary or weekly guaranteed pay. Dillon Transportation, K&B, and some others. The guarantees I've seen are around the $1100-1300 per week. I get a guarantee but sometimes I can double the guarantee, like maybe 2-3 times a year.

IGNORE the Lease-Purchase ads which will advertise weekly revenue of 2-6K. If know how much the company driver ads lie, the lies in L-O ads will rattle your cage.
