Under what circumstances are clearance lights generally turned on?

[VanAnthony]

Clearance lights are generally turned on under the following circumstances: 1. When driving in foggy weather, as visibility decreases and vision becomes blurred, clearance lights should be turned on along with fog lights to provide a good warning effect for other traffic participants on the road; 2. During rainy weather, they serve as a warning for both preceding and following vehicles to minimize potential harm; 3. Nighttime driving requires the use of clearance lights as per traffic regulations, which mandate the activation of rear tail lights and clearance lights to alert following vehicles; 4. When driving at dusk, visibility is challenging due to the absence of streetlights and insufficient brightness of vehicle lights, hence turning on clearance lights enhances visibility for other vehicles and ensures safety.
