What must a dealer do before repossessing a vehicle?

Before repossessing a vehicle, it is important for a dealer to notify law enforcement if possible. This step is crucial because involving law enforcement helps to ensure that the repossession process is conducted legally and safely. By notifying law enforcement, the dealer can take measures to avoid potential conflicts or misunderstandings that may arise during the repossession. Law enforcement can provide assistance and also documentation that may be necessary if disputes occur regarding the repossession.

The other options, while they may seem relevant to the broader context of vehicle repossession, do not fulfill the legal or procedural necessities in the same way. For example, contacting the dealer association is not a required step in the repossession process, as the association generally provides support rather than direct involvement. Notifying the buyer is also not a prerequisite for repossession under many circumstances, although it's often considered a best practice to maintain goodwill. Providing a receipt for payment does not pertain to the repossession process itself, as it relates more to the documentation of sales transactions rather than the actions taken during repossession.
