When is it acceptable to drive using only your parking lights?

Answer: C — Under no circumstances

Using only parking lights while driving is not permitted under any circumstances. Parking lights are designed to make a vehicle visible when parked and are not adequate for providing the necessary illumination for driving or being seen by other road users. Driving without proper headlights reduces visibility, can confuse other drivers regarding your intentions, and significantly increases the risk of accidents. Headlights are essential at night and during poor weather conditions to ensure adequate visibility and safety for both the driver and others on the road. Therefore, the correct response emphasizes the importance of using headlights while driving, which is a critical aspect of safe driving practices.
