Since 1985, what item must dealers display on every used car or light truck for sale?

The correct answer is the Buyers Guide. Since 1985, it has been a federal requirement that dealers display a Buyers Guide on every used car or light truck offered for sale. This document serves several important purposes: it provides essential information about the vehicle’s condition, whether it is being sold "as is" or with a warranty, and it informs potential buyers about their rights. The Buyers Guide also outlines the coverage of any warranties and the terms related to them, thereby facilitating transparency in the sales process.

This requirement is enforced to ensure that consumers are adequately informed before making a purchase, helping prevent miscommunication about the vehicle's status. Displaying a Buyers Guide contributes to a fair marketplace by making sure that buyers have access to critical information that can influence their purchasing decisions.
