USAREUR Practice Exam

When can drivers legally use only parking lights while driving?

1. During snowstorms

2. During dusk or dawn

3. They cannot use only parking lights while driving

4. In well-lit urban areas

The correct answer is: They cannot use only parking lights while driving

Drivers should not use only parking lights while driving under any conditions. Parking lights are designed to make a vehicle visible when it is parked, especially in low-light situations or when on the side of the road. They are not intended for use as driving lights because they do not provide adequate illumination for the road ahead. Using only parking lights while driving could compromise safety by reducing visibility to the driver and to others on the road. In more specific scenarios like snowstorms, dusk or dawn, or in well-lit urban areas, relying solely on parking lights fails to meet the requirements for safe driving. At dusk or dawn, or during adverse weather, full headlights are necessary to ensure the driver can see clearly and be seen by other motorists. Therefore, the correct understanding is that parking lights should not be used in place of headlamps for driving.
