What must all Motor Vehicle dealers post if they are open less than 40 hours per week?

All Motor Vehicle dealers who operate for less than 40 hours a week are required to post a clear, legible sign indicating their hours of operation. This requirement ensures that potential customers are informed about when they can visit the dealership, which is particularly important for those who may be driving a distance or arranging their schedules to coincide with the dealer's hours. A clear sign helps manage customer expectations and enhances transparency in the dealer's operations, thereby fostering trust and accessibility in the business.

In contrast, an advertisement might promote the dealership or specific offers but does not serve the essential function of informing customers about when they can actually visit. Posting a license number is standard practice for dealers, but it does not provide information about operating hours. Therefore, while other options may serve different purposes, the necessity for a clear sign about operational hours directly supports customer service and accessibility, which is why this option is mandated for dealers with limited operating hours.
