What must a customer carry if they are not accompanied by a salesperson during a test drive?

When a customer is not accompanied by a salesperson during a test drive, they must carry a completed form that typically includes information regarding the vehicle being test-driven, the customer's identification details, and any necessary insurance information. This form serves as a protective measure for both parties. It confirms that the customer is authorized to operate the vehicle and that the dealership has taken proper documentation to safeguard against potential liabilities during the test drive. Having this completed form helps ensure that the customer understands their obligations and the terms of the test drive, thereby facilitating a more secure and responsible experience.
