Hazmat parking

make sure the truck is secure and pullem off over night if you are that worried. i wouldnt say anything to them about it. they probably dont know what they are looking at anyhow

 

You're fine. Make sure everything's locked up and that your hazmat docs are visible, usually face up on the driver's seat or dashboard will work.

 

You're very welcome!

 

You are not suppose to leave a hazmat load unattended.

 

Just don't shut down within 5' of a roadway without being within 100' of the truck (sleeper does not count!)

You still can't let the load out of your sight. The right thing to do is sleep in the truck.

 

The section you quoted talks about when the vehicle is located on a public street or highway, or the shoulder of same. The OP said the truck would be in a hotel parking lot, i.e. not on public street/highway.

And according to this, even if he sleeps in the truck then he's not "attending" it -- he would have to be awake.

 

Yep, and to add on to his response, a truck stop or motel parking lot is considered a safe haven. I ran cryo in a day cab, sleeping at motels often. As long as the rig is off the road and parked in a designated area like a parking lot or such, it is OK.
