States with partial bansWhile some states ban car dealerships outright from operating on Sundays, others take a slightly different approach. In Texas and Utah, the law stipulates that you cannot be open on both Saturday and Sunday and must close for business on one of those days. Some states have partial restrictions on selling cars on Sundays. Maryland allows Sunday car sales in four of its counties, Charles, Prince George's, Montgomery, and Howard.Michigan restricts Sunday sales to only those counties with a population of less than 130,000. In 1953, when the law was passed, there were only eight counties with a population of more than 130,000. Now, there are more than twice that many. In Clark County, Nevada (the home of Las Vegas), you can buy and sell second-hand cars on a Sunday, but not new ones (provided the second-hand vehicles aren't being sold at the same location as new ones). Rhode Island is okay with car dealerships opening on Sundays, but they are limited to opening hours of between 12 p.m. and 6 p.m.
