Wasn't where I took it. Was a written test, then (though I sorta' remember the written test might have happened some number of days before or somethin'?) a fairly short drive down the road, a left turn, shorter drive down dirt road, three point turn, then returning to the DMV office. Demonstration of ability to park and basic "Don't be stupid" stuff like putting on your seatbelt, using blinkers, etc. Practical part didn't even take twenty minutes, near as I can recall. Don't believe there was anything about maintenance at all... maybe a check to see if you knew how to check the oil? If there was, it wasn't much and wasn't particularly comprehensive.
I guess to be fair, it would have taken more than a 45 minute drive to reach traffic worth mention from there, and the only particular driving conditions in between are light traffic (which the drive to the dirt road covered), dirt road with little to no traffic (covered), and offroad, which they mostly don't give two shits if you kill yourself doing. Could have maybe made it to the interstate (though just getting there would probably have added a half hour or so, total, nevermind actually driving on it), but about all that would check in th'region the test was taken was if you can keep the car going straight when you're going 65.
Pretty sure the driving lessons (provided by the schools, among other options) in the area actually do do something like that more thorough test as part of their programs, though. It's just, as stated, they're not mandatory, and I never ended up taking them.
