What are these terms...

Live Load/Unload is the only one I can help you with. xD

"Live" means that you're backed in a dock and they're either loading or unloading you while you wait.

Hot load... my mind went straight to the gutter... sorry.

 

T Call is a term used for the Qualcomm.
It's a macro you use to check call to send in loaded info or some such thing that a company wants to know. But it's on the satellite communications system that a lot of companies use to keep tabs on you. call it Big Brother

 

JT or JIT - just in time

Similar to a hot load, but under no circumstance can a driver be late on a delivery deadline. The truck company can be fined for late JT loads. Drivers can be terminated.

 

HV - High Value Load

These are loads that are valued at significant amounts of money. Very expensive loads. Think furniture or electronics. When I worked at Knight, I hauled a trailer full of Red Bull that had a security bolt on a trailer instead of a regular seal. The value exceeded 80,000 dollars....for mere energy drinks! High value? Very.

 

T-call, "T" means transfer. You are assigned a load but don't deliver it to its destination, you are dropping it in a terminal/drop yard and it's transferred to another driver.

 

Drop and Hook - drop an empty or loaded trailer at a shipper/receiver and pick up another trailer, depending on where you are, that will either be empty or loaded.

Example, drop and hook at a receiver with a loaded trailer, you will be picking up an empty trailer. Do this at a shipper and you'll likely be dropping an empty to pick up a loaded trailer.

 

hot load usually means no way to make it on time legally

 

T-call can mean temperature check too if you are hauling reefer. They want you to call in your temps twice a day.
