What must be done if any exterior light is covered?

Clearing the obstruction is crucial because exterior lights are designed to enhance visibility and safety on the road. If a light is covered, it may not function effectively, which can reduce visibility for the driver and other road users, increasing the risk of accidents. Ensuring that these lights are unobstructed allows for proper illumination, signaling, and compliance with safety regulations. This is especially important for turn signals, brake lights, and headlights, as they communicate vital information to other drivers. By removing any coverings, you help to maintain the effectiveness and reliability of the vehicle's lighting system, contributing to overall road safety.
