What are lines painted on escalator steps to make the edge more visible?

• A. Step Lines
• B. Edge Lines
• C. Safety Lines
• D. Tread Lines

Answer: (A)

Visual cues on escalator steps are used to reveal the edge so riders can clearly see where each step ends and the next begins. The lines are painted across the tread near the front edge, creating a high-contrast boundary that the eye can quickly pick up as the steps move. This helps prevent missteps and keeps shoes from catching on the edge, especially for people who might have limited depth perception or are in a hurry. Safety standards often specify bright, contrasting colors for these markings to maximize visibility, reinforcing the practice across public escalators. This specific term—step lines—describes those markings on the step surfaces themselves, making them the most precise and descriptive choice.
