The maximum height of wheelchair lifts can be stated as which of the following numbers in feet?

• A. 24 feet
• B. 34 feet
• C. 44 feet
• D. 14 feet

Answer: (D)

The main idea here is that wheelchair lifts used inside buildings have a practical upper limit on how far they can travel in one motion. For vertical platform lifts, the common, safe, and manufactured maximum travel is about fourteen feet. This distance is enough to reach another level in many two-story interiors and fits within typical safety, control, and mechanical design constraints of a single lift shaft.

Longer travels—like twenty-four, thirty-four, or forty-four feet—enter territory where a single lift becomes impractical or unsafe and would usually require a different solution, such as a full elevator or a staged system with multiple components. So fourteen feet is the best answer because it reflects the standard maximum travel for a standard in-building wheelchair lift.
