Detention
The fee you charge when a shipper or receiver holds your truck past the free time to load or unload.
Detention is what you get paid when a shipper or receiver keeps your truck waiting too long. Most facilities give you a window of free time to load or unload, usually two hours. Past that, the clock starts and you can bill detention for every hour they hold you.
The catch is that detention only sticks if you can prove it. You need your arrival time and your departure time documented, and the rate con usually spells out the free time, the hourly rate, and how they want it claimed. Get your in and out times noted on the paperwork or logged the moment they happen.
Detention is real money that owner-operators leave on the table all the time because they did not track the hours or missed the claim window. Those waiting hours are hours you cannot spend driving, so charging for them is not greedy, it is the cost of the delay.
