Final answer:
The statement is true; you are generally required to have your headlights on when using windshield wipers during daylight hours on a rainy day to improve visibility and safety. However, laws may vary by jurisdiction.
Step-by-step explanation:
If your windshield wipers are on during daylight hours on a rainy day, you are required to turn your headlights on. The answer is true. This law, known as the "wipers on, headlights on" rule, is implemented in many places to enhance the visibility of vehicles during inclement weather conditions.
Turning on your headlights increases both your ability to see and other drivers' ability to see your car. This safety regulation aids in preventing accidents caused by poor visibility. However, it's essential to note that this law can vary by state or country, so it's crucial to be familiar with the local traffic laws.
