A ramp has a rise of 7 inches and a length of 80 inches. How many handrails are required?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

The key idea is that many accessibility rules require handrails on ramps that are both tall and long enough to need two supports. Specifically, if a ramp rises more than 6 inches and its length exceeds 72 inches, handrails must be provided on both sides.

This ramp rises 7 inches and runs 80 inches, so it meets both thresholds. That means handrails are needed on each side of the ramp, totaling two handrails. A single handrail wouldn’t meet the requirement here because the ramp is tall enough and long enough to justify support on both sides. Having more than two handrails isn’t necessary for this scenario, so options proposing three or four handrails aren’t correct.
