What do clearance lamps indicate on a vehicle?

Clearance lamps are designed to indicate the overall width and height of a vehicle, especially in situations where the vehicle might be difficult to see from a distance or in poor visibility conditions. These lights are typically positioned at the top or corners of the vehicle to help other drivers gauge the dimensions of the vehicle, particularly for larger vehicles such as trucks and buses.

By clearly showing the extent of the vehicle, clearance lamps aid in preventing accidents and ensuring safer navigation on the road. The visibility provided by these lamps becomes crucial during nighttime or in adverse weather conditions, as they allow other road users to maintain a safe distance and make informed decisions about lane changes or overtaking maneuvers.

In contrast, options discussing speed and performance, load capacity, or oil levels pertain to different vehicle functionalities and do not relate to the specific purpose of clearance lamps.
