1.
A newly constructed office building has an accessible parking
area, but the route from the accessible spaces crosses a
vehicular drive that is also used as a loading area. Which
principle is most important when evaluating the accessible
route?
A. The route is acceptable because accessible parking itself
satisfies the requirement.
B. The route is acceptable only if it is less than 200 feet long.
C. The accessible route must connect the site arrival point to
an accessible entrance and comply with applicable accessible-
route requirements.
D. The route is acceptable if a sign identifies the crossing.
Rationale: C is correct because accessible parking spaces are
site arrival points that must be connected by an accessible route
,to the accessible entrance they serve. The ADA Standards do not
treat the mere provision of an accessible parking space as
sufficient. The route must provide an actual accessible
pedestrian connection. A sign does not substitute for an
accessible route, and the 200-foot measurement is associated
with passing spaces on certain narrow accessible routes, not
with the basic obligation to connect parking to an entrance.
2.
A ramp serving an accessible entrance has a running slope of
1:12. Which statement is most accurate under the 2010 ADA
Standards?
A. The slope is too steep for any accessible route.
B. The slope is the maximum permitted running slope for a
standard ramp run.
C. The slope is permitted only in existing facilities.
D. The slope is permitted only when handrails are omitted.
Rationale: B is correct. A ramp run generally may not have a
running slope steeper than 1:12. A 1:12 slope therefore
represents the maximum standard slope, although a less-steep
slope is generally preferable. Existing facilities have limited
exceptions permitting certain steeper slopes where space
limitations exist, but those exceptions do not change the
standard requirement for newly constructed ramps.
,3.
What is the maximum vertical rise permitted for a single ramp
run under the 2010 ADA Standards?
A. 24 inches
B. 30 inches
C. 36 inches
D. 48 inches
Rationale: B is correct. A ramp run may rise a maximum of 30
inches vertically before a landing is required. This limitation is
separate from the 1:12 maximum running slope. Thus, even
when a ramp is correctly sloped, its vertical rise cannot simply
continue indefinitely without an intermediate landing.
4.
A designer proposes an accessible route consisting of a walking
surface with a running slope of 1:20. How is this component
classified under the ADA Standards?
A. It is a walking surface and does not constitute a ramp solely
because of its slope.
B. It is automatically classified as a ramp.
C. It is prohibited because every accessible route must be level.
D. It is permitted only in residential facilities.
Rationale: A is correct. The ADA Standards distinguish walking
surfaces from ramps. A walking surface with a running slope
, not steeper than 1:20 is generally treated as a walking surface
rather than a ramp. Once the slope exceeds 1:20, the
requirements applicable to ramps may become relevant.
5.
Two accessible parking spaces are arranged side by side. What
is expressly permitted regarding their access aisles?
A. Each space must have a separate aisle.
B. Only van spaces may share an aisle.
C. The two spaces may share a common access aisle.
D. Shared aisles are permitted only in parking garages.
Rationale: C is correct. The ADA Standards expressly permit two
accessible parking spaces to share a common access aisle. The
access aisle must still comply with the applicable width and
location requirements and must adjoin an accessible route. The
sharing provision is intended to allow efficient parking layouts
without reducing the required accessible circulation space.
6.
Under the 2010 ADA Standards, what is the minimum width of
a standard accessible car parking space?
A. 84 inches
B. 96 inches
C. 108 inches
D. 132 inches
