ADA Door Clearance - NCARB Practice Test Question
One of the case studies in the NCARB practice exam is as follows:
I'm confused by the highlighted sections. For context, the ADA clearances are provided below (they were also provided in the exam):
My assumption was that the door in the question would be either front approach (pull side) or latch approach (pull side). If it were front approach, which seemed most likely to me, then the clearance would be 18", whereas if it were latch approach it would be 24". 24" was not a possible answer, but 18 was (highlighted in yellow in the first image). I had assumed that by process of elimination, 18" is the correct answer. I was a bit thrown off by the fact that the minimum maneuvering clearance perpendicular to doorway given in the question was 54", while the ADA door clearance say that for front approach pull side it must be 60", but again 24" was not a possible answer.
The correct response explanation confirms that the clearance should be based on a latched approach pull side, which again would mean a 24" which isn't an option. Instead the correct response was supposed to be 42", which is the clearance for a hinge approach. I think this may just be an error, and it was supposed to be latch approach with a 24" clearance, but I'm not sure and even so to me the position of the door made me think it was most likely a front approach, which led me to answer incorrectly.
My question is how is it determined if a door is latch approach, hinge approach, or latch approach?

PDD Practice Exam Question - Door Swings
Also please note that the response to this item was posted off topic of the thread. The question regarding the door swing and approach is towards the bottom of the link in that thread.
Thank you for bringing this question and your comments here.
This is already second question that I saw today on this forum which had incorrect answer options in this PA test exam.
Plus I also have one more to write about in a separate topic. The answer I provided was correct, but it resulted as "incorrect" due to some graphic imperfections of the computer program, which is really frustrating.
