True

In Little Rock, Arkansas, a 1920s-era law still on the books says that after 9pm, you can’t honk your horn “at any place where cold drinks and/or sandwiches are served.”

Back then, drive-in restaurants with curbside service were such the rage that motorists would honk to get a carhop’s attention. One can imagine how annoying this would get. So, not only did the law stay on the books, but it was amended in 1961 to add the 9pm ordinance—revised from 11pm.
