What is MOTd
I’m guessing this: en.wikipedia.org/wiki/MOT_test
MOT test - Wikipedia

Oh yep, in Australia we colloquially call it “the pits” as in “Gotta take the car to the pits” but I’d say the more universal term would be checking the vehicle’s roadworthiness, or taking it for a roadworthy.
We call it getting it “smogged” in Los Angeles as the concern is cutting emissions to reduce smog; though many of the requirements are naturally related to road worthiness too.
Bunch of states have the same as MOT, called “inspection”.
Yep of course! I’m just not familiar with other states’ terminology.
