A line of credit can be used as an alternative to a traditional loan and provides flexibility in that it allows borrowers to draw on their funds as needed, as long as they stay within the total credit limit. Using a line of credit offers convenient access to funds at relatively low interest rates. A trucking business line of credit works in much the same way as a traditional credit card or loan. It is a line of credit available to businesses, in which a bank provides a certain amount of funds that the business can draw on whenever needed. As the company draws funds from the line of credit, it must repay the borrowed amount in full, plus any accrued interest.
