What should you do if your windshield wipers are in use, according to Virginia law?

In Virginia, if your windshield wipers are in use, the law mandates that you must use your headlights. This requirement ensures that not only are you able to see better in conditions where visibility might be compromised, such as rain or snow, but it also allows other drivers to see your vehicle more clearly. Using headlights adds to overall road safety by enhancing visibility for all road users, especially during adverse weather conditions where the effectiveness of windshield wipers is utilized.

While the other options—reducing speed, driving with caution, and keeping windows clear—are all important driving practices, they are not specifically mandated by law in conjunction with using windshield wipers. Using headlights is a specific legal requirement that directly ties to ensuring safe driving in poor visibility conditions.
