Brokers often post loads available that do not require you to have a trailer, and they already have one ready. They need your power unit (semi-truck). Those are called “Power Only.” Different load boards may list them differently, but the meaning is the same. Make sure you verify with the broker if you are not sure.
Example: Booking a load that only Requires you to have a Semi truck while pulling someone else’s trailer.
Used in a sentence: John was Booking Power Only loads that require the use of just your semi-truck.
