What type of lamps must be used to indicate the clearance of a vehicle?

Clearance lamps are specifically designed to indicate the height and width of a vehicle, helping to ensure that other road users are aware of its dimensions. They are typically positioned at the front and rear of the vehicle, and their primary function is to enhance visibility, especially for larger vehicles like trucks and trailers that might otherwise be difficult to see in certain situations.

The use of clearance lamps is crucial for safety, as they help prevent accidents by clearly signaling the vehicle's extremities to other drivers, especially in low-visibility conditions or nighttime driving. This compliance with safety regulations is essential for transporting goods and ensuring road safety.

Other types of lamps, such as reflective lamps, marker lamps, and signal lamps, serve different purposes. Reflective lamps generally enhance the visibility of a vehicle through reflection rather than illumination. Marker lamps are often used to indicate the presence of a vehicle but do not provide the same specific indication of clearance as clearance lamps do. Signal lamps, on the other hand, are utilized primarily for signaling intentions, such as turning or stopping, rather than for indicating the physical dimensions of the vehicle. Therefore, clearance lamps are the necessary choice for conveying vehicle clearance effectively.
