What is the function of reflective gear during vehicle inspections?

Reflective gear serves a critical safety function during vehicle inspections by ensuring that the driver is visible to others, especially in low-light conditions or in areas with high traffic. Wearing reflective clothing helps increase visibility, making it easier for other drivers, pedestrians, and individuals working in the vicinity to see the inspection personnel. This visibility is vital for preventing accidents and ensuring the safety of everyone involved during the inspection process.

The other options do not accurately reflect the primary purpose of reflective gear. For instance, reflective gear is not used for decorating a vehicle or for repairing it. Additionally, while staying cool in hot weather is beneficial, reflective gear is designed mainly for visibility and safety, not for temperature regulation. This focus on visibility is why the correct answer highlights this essential safety aspect.
