What is a common safety feature found on work zone vehicles?

Flashing lights and reflective surfaces are essential safety features found on work zone vehicles because they enhance visibility for both the work crews and road users. These features are crucial in alerting drivers to the presence of construction or maintenance activities, especially in low-light conditions or adverse weather. The bright, flashing lights are designed to attract attention and signal caution, reducing the likelihood of accidents. Reflective surfaces further improve visibility by reflecting headlights from vehicles, ensuring that the work zone is easily seen from a distance.

In contrast, high-powered engines, large cargo beds, and low-profile tires do not primarily serve a safety function for work zones. While they may contribute to the overall utility of the vehicle, they are not specifically designed to enhance visibility or indicate the presence of workers, which are the primary concerns in a work zone setting.
