What does the term REFL signify in a vehicle inspection?

The term REFL in a vehicle inspection context refers to "Reflector." Reflectors are critical components on vehicles, especially commercial ones, as they enhance visibility and safety during nighttime or low-light conditions. They are designed to reflect light from other sources, such as headlights from vehicles, thereby making the vehicle more visible to other drivers. This is crucial for preventing accidents and ensuring compliance with safety regulations. Proper functioning and positioning of reflectors are part of the inspection process to ensure that all safety features of the vehicle meet regulatory standards.
