What is the primary purpose of reflective tape on trucks?

The primary purpose of reflective tape on trucks is to enhance visibility in low-light conditions. Reflective tape is designed to reflect light back to its source, making the vehicle more noticeable to other drivers, especially at night or in poor weather conditions. This increased visibility is crucial for safety, as it helps to alert other road users to the presence of the truck, reducing the risk of accidents.

In contrast, options related to corrosion prevention, decorative appearance, or aerodynamics do not accurately reflect the function of reflective tape. While these elements may be important in other contexts, they do not pertain to the main objective of using reflective tape, which is to ensure safety by improving visibility and making the truck more recognizable in various driving conditions.
