When my wife and I took our tests, the instructor made a point during the classroom session to say "All weapons that have safeties must have them engaged when they aren't being fired." He also pointed out that people with most revolvers, and Glocks were exempt since they don't have external safeties. During the shooting portion, after each round, once we cleared our weapons and set them down, he would come by and check, definitely for clear, presumably for safeties engaged(My wife and I tested on Glocks, so I can't speak the accuracy of his checks.). Hope that helps.
