What are my rights as an employee in this situation?

Short run down: I am part of a two person team (there are seventy teams total) that travel from college to college in an area of the US selling posters for anywhere from one day to two weeks at each school.

Tomorrow we have a sale in Kentucky and wednesday we have a sale in Virginia eight hours away. This week is all one day sales and theyre all very spread apart. After driving eight hours tuesday night, we are supposed to drive another five both Wednesday and Thursday night, after days of waking up at six AM and doing physical labor loading and unloading the truck, then working the actual sale for approx. Ten hours each day. Not to mention after these insane drives we have about an hour of accounting to do at the hotel before we can sleep.

The problem: 8 hours is unrealistic to begin with. To top it off, our truck is huge and 8 hours on google maps is more like 10 for our truck, especially in mountainous West Virginia, where we will be driving through (and where we drove through last night and spent a long time going up hills at twenty miles an hour…our truck is automatic and just doesnt do well) not only are the logistics of it fucked up, but its straight up dangerous. And, since we are in a big truck, we have to fill out DOT trucker log books, and we are working waaaay over the legal limit of hours and essentially have to fudge them so that if we get pulled over we dont get fined.

So….what can I do? I know there has to be something. Please help.
