If you aren't crossing on an autobahn, you won't really notice the border. If you are on the autobahn, there is a border truck stop/station.
Austria requires two things to drive on their autobahns. First they sell a sticker for your car that is the equivalent of a road tax in lieu of toll booths. If you stay off the "freeways", you don't need the sticker.
You also need an orange vest in case you have a breakdown.
Since the Germanic people are such sticklers for regulations, I wouldn't even try to avoid compliance. I can't recall the exact prices. The sticker was about what I expected (maybe 25-35 euros) and the vest was cheap considering they had you over a barrel (about 5 euros).
There will be a border gas/restaurant/station where you can get gas, food (if you want trucker food), and the sticker and vest.
I left the sticker on the car when I turned it in and kept the vest as a souvenir for my car at home.
