What does there is no lien on a vehicle means?

When there is no lien on a vehicle, it means that the vehicle is owned outright by the owner and is not being used as collateral for a loan or debt. This indicates that there are no legal claims or financial obligations attached to the vehicle, making it free to sell or transfer without any encumbrances. Essentially, the owner has full rights to the vehicle without any creditors having a stake in it.
