ADAAG Manual

Wheelchair Turning Space [4.2.3]

Circular Turns

The most efficient way of making a half or full turn in a manual wheelchair is by turning the wheels in opposing directions. Repeated maneuvering is often necessary for people unable to turn this way, including those who use motorized wheelchairs and scooters. Recommendation: Larger space in the shape of an oval, as recommended in the ADAAG appendix, can allow easier maneuvering for turns.

T-Shaped Turns

Space for 3-point turns can be provided in the space of a T. This space can be configured for approach on any segment of the T. Recommendation: Additional space that allows 60 inches (1525 mm) on each leg of both turns will ease maneuvering.

Overlapping Fixed Elements

Fixed elements can overlap turning space if required knee and toe clearances are provided. Since maneuvering for turns varies, the overlap of fixed elements should be minimized. Recommendation: Where space for turns is confined to the minimum, consider limiting the overlap so that wheelchair space (30 by 48 inches minimum) remains clear.

Generally, the depth of usable floor space below fixed elements with knee and toe clearance is limited to 19 inches. The overlap of turning space must be limited to one segment of the T so that back-up maneuvering is not restricted. On the short segment of the T, the overlap must be limited to 12 inches; on the long segment of the T, an overlap up to 19 inches is permitted.
