It is unlawful to drive a car without windshield wipers, even if there is no windshield.

The Law Explained

This bizarre loophole stems from the rigid wording of the state's vehicle safety inspection code. The law mandates that every motor vehicle must be equipped with functional wipers, but forgot to explicitly state that a windshield is required first. As a result, even dune buggies and stripped-down hot rods must legally have a wiper motor attached.
