When selecting doorway thresholds, which design is recommended to preserve accessibility?

• A. Beveled thresholds that do not impede passage and minimize trip hazards
• B. Thick solid thresholds that raise floor level
• C. Thin metal strips with sharp edges
• D. No threshold at all is ever allowed

Answer: (A)

The main idea is creating doorway transitions that stay smooth for everyone, including wheelchairs and walkers, while reducing the risk of trips and maintaining a weather seal. A beveled threshold does this best: it provides a gentle slope at the doorway edge so a wheelchair or mobility aid can roll over without catching, and it minimizes trip hazards for pedestrians. This keeps the surface continuous and accessible without creating a new barrier at the threshold. Thick solid thresholds that raise the floor level present a real obstacle for mobility devices, making it harder to cross and increasing the chance of tipping or getting stuck. Thin metal strips with sharp edges can catch wheels or skin, causing safety issues. The statement that no threshold at all is ever allowed is not accurate—some entries require a threshold or a flush, weather-sealing transition, but ruling out any threshold entirely isn’t practical or necessary for accessibility.
