Not all car dealers are closed on Sundays, but many are not open due to local laws that restrict the sale of automobiles on certain days. As of 2015, 18 states have at least some restriction on the sale of cars on Sundays. These restrictions are often related to restrictions placed on alcohol sales on Sundays, which are often referred to as "blue laws." The primary goal of these laws is to prevent people from working on the Christian Sabbath.
In several states, such as New Jersey, Illinois, and Ohio, the sale of automobiles is completely banned on Sundays. In Utah and Texas, car dealers must be closed on either Saturday or Sunday, but do not have to close for both days. North Dakota allows car dealers to be open on Sundays, but no car sales are allowed. Other states place restrictions on the times that car dealers can be open on Sundays, while others leave the determination as to whether car dealers can be open on Sundays up to each county.
Many view these laws as antiquated holdovers from previous generations. Many car dealers located in jurisdictions that prohibit or limit Sunday car sales believe that their business is being hurt by these types of laws. In support of their argument, car dealers often cite the fact that many workers throughout the United States are only off on Sundays and are forced to use time off from work in order to test drive and purchase a vehicle.
