Term clarification

1. paperwork gets sent in. usually big yellow box near the truck stop entrance. it's there paperwork to bill the reciever.
2. box on your windshield that lets you bypass scales. only if a green light comes on. if the red light comes on you have to stop.
3. that one is new to me. might be a different phrasing from something else. thats probably gonna be something like, they give you a work schedule and you have to do it since they have no one to cover it but you and would highly look down on you calling in "sick". now that is just a guess but recruiting at said company will tell you what this means for sure. just ask them.
4. usually work days before scheduled time off. but usually runs anywhere from 5-14 days depending on who you work for with 34 hrs to 4 days off.
