When can you legally drive with your parking lights on?

Answer: B — Only when parked

Driving with only parking lights activated is permissible only when a vehicle is parked. Parking lights are designed to increase visibility and alert other drivers to the presence of a vehicle that is stationary, especially in low-light conditions. While there are specific situations, like being in inclement weather, where reduced visibility may require the use of headlights or other lights, parking lights alone do not provide adequate illumination necessary for safe driving. Therefore, they should never be used as a substitute for your regular headlights during actual driving situations. Additionally, using parking lights while driving can confuse other drivers because these lights are not intended to convey that a vehicle is in motion. It’s important to use the right lights according to the driving situation to enhance safety and comply with traffic regulations.
